1049-07 rev B 02/10/03 /33 ______________________________________________________________________________________ 4. OPERATION

4.1. Display Odometer

The odometer value will be displayed with the ignition off when the vehicle lights are turned on as long as the panel dimmer level is greater than approximately 10%.

4.2. Turn signal/Hazard warning lights

The right and left turn icons are operational with the ignition off when their respective binary input becomes high. Hazard lights normally turn both the right and left turn binary inputs high.

4.3. Start-Up Mode

The Master enters start-up mode when the ignition is turned on. The ignition binary input is used to sense if the key switch is on or off.

The start up self-test is an option enabled through the setup menu. The factory setting for this option is enabled.

4.3.1. GAUGES

Gauge pointers will drive to zero position. The pointers will then drive up scale, pausing at ½ scale, before completing the sweep to full scale. The pointers will then return to zero position before moving to the commanded position.

4.3.2. LCD

During the up scale sweep of the pointers, the LCD will turn all its segments on for one second, off for one second and then display the opening message. The opening message is the Freightliner logo followed by the software ID, complete with revision level.

4.3.3. WARNING LIGHTS

Starting at the up scale pointer sweep, all warning lights will turn on for 5 seconds and then go out. Active warning lights will turn on when the gauges go to their commanded position.

4.3.4. COMMUNICATION

The speedometer will determine which data buses are connected and which devices are present. Error messages will display if a data bus is missing or a device that had been previously found is now missing.

4.3.5. AUDIBLE ALARM

The audible alarm will sound its three different tones for one second each during the up scale swing of the pointers.


1049-07 rev B 02/10/03 /33 ______________________________________________________________________________________ 4.4. Turn-off

When the ignition line goes low all gauges will zero, except the fuel gauge, and the odometer value will be stored to the EEPROM before the IP turns itself off. This will take up to 4 seconds. While off, the instrument panel will consume less than 1mA from the hot battery power input.

4.5. Self-Diagnostic Mode

The self-diagnostic mode is entered through a menu selection using the LCD. Diagnostics is only available when the Park Brake is set.

Detail specifications are found in the Message Display Center section.

The self-diagnostic includes the following tests: �� Gauges �� LCD �� Warning Lights �� Binary Inputs �� Analog Inputs �� Communications

1049-07 rev B 02/10/03 /33 ______________________________________________________________________________________ 6. COMMUNICATION

There are two communication channels for data transfer between the vehicle and the speedometer. One channel for SAE J1708/J1587 and a second channel for CAN 2.0B/SAE J1939 (Controller Area Network).

All frames transmitted by the speedometer on J1939 are continuously sent at the standard broadcast rate for the frame using source address (SA) 23dec (17h).

The speedometer communicates via the LIN bus to slave devices. The slave gauges are updated every 400mSec except for the tachometer which is updated every 80mSec.

6.1. Communication Errors

If a parameter is not received by J1939 for 5 seconds it will be flagged as missing. Missing LCD information will display a “-“ and missing gauge information will be signaled by wagging the pointer from dial end to dial end. A missing J1939 data bus will be announced in the LCD. If a LIN parameter is missing for 5 seconds the gauge will wag the pointer from dial end to dial end and flash the warning LED.

6.2. Messages Sent

6.2.1. CRUISE ON/OFF – PTO ON/OFF

The Cruise On/Off message is sent to the engine via J1939 ( PGN65265ON_OFF) when the cruise On/Off maintained switch is switched low. The PTO On/Off message will also be sent via J1939 (PGN65264ON_OFF)

6.2.9. AUTOMATIC HIGH IDLE LOW VOLTAGE

If battery voltage reported on J1939 is <12.2V the gauge will command the engine to increase idle speed using Power Takeoff Information PGN 65,264 under the following conditions:

PTO is not currently ON per (PGN65265PTO) Park brake is set Transmission is in Neutral or Park Service brake pedal is not pressed

The master sends PTO enable (PGN65264ON_OFF) and PTO set (PGN65264Set) The LCD displays “Auto Hi Idle Lo V” on the second line, flashing the message in normal and reverse video. The engine speed will increase to minimum PTO speed

The master will wait 5 seconds If Battery voltage is <13.4V

The master will send PTO resume/increment) one time (PGN65264Resume) The engine idle speed will increase one step

This loop will repeat every 5 seconds If Battery voltage � 13.4V the present PTO speed will be maintained The master sends disable PTO (PGN65264ON_OFF) to turn off High Idle Low Voltage if:

The park brake is released The transmission is shifted from neutral or park The service brake pedal is pressed

Anytime automatic high idle low voltage is disabled, the LCD second line will revert back to displaying the selected default information.

Should the PTO enable switch, set switch, or resume switch change states during automatic low voltage/high idle operation, the user will be given manual control of the PTO functions and automatic low voltage/high idle will be disabled until the park brake is released and reset, the transmission is shifted out of neutral/park and back in, or the key is cycled.

The Low Voltage High Idle function can be enabled and disabled through PC gauge diagnostic software and the function’s status (enable/disable) can be viewed through the setup menu.

1049-07 rev B 02/10/03 /33 ______________________________________________________________________________________ 7.3. Odometer

The odometer function is in the speedometer. The season odometer displays 0.0 - 9,999,999.9 and the trip odometer, when offered, will display 0.0 - 9999.9. Both have a resolution of 0.1 mi/km. Leading zeros are only displayed in the 1’s position. The vehicle distance is calculated every 80 msec. from the vehicle speed transmitted on the J1939 data bus by the engine ECM and stored within the speedometer in kilometers. It can be displayed on the LCD in miles or kilometers. The odometer reading will be displayed when the ignition switch is off by activating the gauge backlight.

7.3.1. ACCURACY

Accuracy of the odometer value is dependant on two (2) main variables. 1) The algorithm in the speedometer for calculating distance, and 2) the speed value transmitted by the ECM. The algorithm has been designed and written to calculate the distance with the accuracy and resolution necessary to exceed SAE recommendations. The distance is calculated every 80 msec. to reduce error during any rapid speed change the vehicle might make. The speed data is dependant on the calibration parameters for tire size and axle ratio being properly entered into the ECM. These are the same parameters necessary to have the ECM properly calculate the vehicle speed and distance value. Testing has indicated that the algorithm will calculate mileage within �0.07% of actual based on the speed received. This far exceeds the SAE recommended �0.3% found in SAE J1226.

7.3.2. ENGINE/ODOMETER DIFFERENCE

At ignition on, if the engine’s Total Vehicle Distance (TVD) does not equal the stored odometer value, and is not within the range 0-2km, then the gauge will determine an “odometer difference” between the engine’s TVD and the stored odometer value. The “odometer difference” will be saved in EEPROM and used to determine odometer match. This scenario will occur when the speedometer is replaced in the field, which will cause a positive “odometer difference” because the new odometer starts at zero. It will also occur when an engine control module is replace in the field, which will cause a negative “odometer difference”.

The “odometer difference” is the engine’s TVD value minus the stored odometer value. The odometer will use this “difference” value to keep a constant delta between the engine’s TVD and the stored odometer value. After the “odometer difference” has been saved, the odometer will again match the engine’s TVD if the odometer stored value is within the “difference” range of 0-2km.

7.3.3. ENGINE/ODOMETER MATCH

The odometer will match the engine’s broadcast TVD parameter value if the odometer is within 0-2km. This comparison will occur at every ignition on power cycle. At ignition on, if the (stored odometer value + odometer difference) equals engine’s TVD the stored odometer value will be used and the odometer will increment from there. At ignition on, if the (stored odometer value + odometer difference) does not equal the engine’s TVD, but is in the range of 0-2km, then the stored odometer value will correct so the (stored odometer value + odometer difference) will match the TVD and the odometer will increment from there. The odometer can gain up to 2.0km to match the engine, but is not allowed to lose distance


1049-07 rev B 02/10/03 /33 ______________________________________________________________________________________

7.3.4. NORMAL SHUTDOWN

The odometer value is stored to the EEPROM at each 1-kilometer increment (0.62 mi) and when the ignition switch is turned off. The value is stored to 1/100 of a kilometer resolution (33 ft) using a 4-byte memory location within an array. Each store is made sequentially to one (1) of eight (8) locations in the array so at any point in time the last eight (8) values are maintained. Each value stored is verified at the time it is saved. Multiple store attempts to a location will be made if necessary, and if not successful, the memory location will be tagged as bad. The "precount" that is used to increment the odometer every 1/100th km is also saved. The "precount value is 115200. Therefore, our internal resolution is 1/11520000th of a km or 0.003385827 inches. This value is stored on power down and recovered on power up.

7.3.5. ABNORMAL SHUTDOWN

If there is battery power loss at the speedometer prior to turning the ignition off, an abnormal shut down will occur. The odometer value, when power is restored, will return to the last kilometer increment value saved; i.e. the last XXX.0 kilometer rollover. Therefore, the maximum distance lost by an abnormal shutdown will be 0.9 km (0.56 mi). Battery loss that occurs >4 seconds after turning the ignition off will NOT result in an abnormal shutdown. The occurrence of an abnormal shutdown during the life of a vehicle should be rare.

7.3.6. DURABILITY

The EEPROM store routine will allow for a minimum of 4 million store cycles. The design will accommodate 200 key-offs per day, 260 days per year, for 20 years plus 1.609344 million kilometers (1,000,000 mi) which could be seen if the vehicle is used on a delivery route, with a 51% safety factor (200*260*20+1,609,334) = 2,649,334+51% = 4,000,494 store cycles. An error recovery scheme is implemented that will allow the odometer value to be recovered should a hardware failure in one of the EEPROM memory cells occur.

7.3.7. ERROR RECOVERY

The error recovery algorithm will check each stored value to determine if the values are in sequence (low to high) and 1 km or less apart. If this condition is found no errors are present and no further action is required. If a value is found to be out of order or greater than 1 km from the others, the software will identify the largest value in the group with the proper sequence and use that value. In the unlikely event the speedometer fails in such a way that the odometer value cannot be displayed, the factory, in most instances, will be able to recover the stored value.


1049-07 rev B 02/10/03 /33 ______________________________________________________________________________________

7.3.8. MAXIMUM READING

The odometer will stop incrementing when the maximum display count is reached. Therefore, the value will not rollover to zero and continue incrementing but will freeze at 9,999,999.9.

7.3.9. SERVICE PROGRAMMING

If replacement of the speedometer becomes necessary, the actual vehicle mileage may be programmed into the odometer using Actia proprietary software. The mileage may be incremented, but not decremented, using this software. If desired, replacement speedometers will be shipped in a mode that allows the installer to preset actual vehicle distance, thus eliminating the need to “tag” the vehicle.

7.4. Priority Messages

Priority messages are displayed in the LCD due to various inputs or data messages. Unless noted otherwise, the priority message will take over the whole screen allowing multiple messages to be displayed and can be acknowledged by pressing the m button at which time they will leave the display.
