Controller Area NetworkController Area Network

• Primary purpose is to network vehicle control module using a Standard protocol– Reduces redundant sensors and or wiring

(multiplexing)• reducing weight and increasing reliability

– Using serial data bus to transfer data• Allowing for reliable multiple processor instead of one

unreliable large one

Modes Of Communication

5

OBD II Modes

• MODE 1– Request For Current Power train

Diagnostic Data• MODE 2

– Request for Freeze Frame Data• MODE 3

– Request for the Emission Related Trouble Codes

6

OBD II Modes

• MODE 4– Request to Clear/Reset Diagnostic

Trouble Codes

• MODE 5– Request Oxygen Sensor Monitoring

Test Results

7

OBD II Mode 6 and 7

• MODE 6– Request for the latest on-board

monitoring test results for non-continuous test results

• MODE 7– Request for the latest on-board

monitoring test results for continuous monitoring systems

8

Mode 8 and 9• Mode 8

– Request control of a On-Board System, Test, or Component

• Mode 9– Request for Vehicle Identification

Number and Calibration IDs

Mode 6

Mode 6 Example EGR Monitor

• The PCM will compare test from a Hexadecimal chart

Test ID Description Test Value Test Limit1 2 3 4Min 5Max 6Min 7Max

• Before the monitor test begins the following must be completed– Engine at operating temperature– 3 minutes since start up– RPM at specified spec– MAP voltage at specified spec– TPS at specified spec– Vehicle speed at specified spec– STFT at a given minimum level

EGR Monitor

12

EGR Monitor

• PCM monitors by change in Short Term Fuel Trim– During operation of the EGR system the PCM will

momentarily shut down the EGR solenoid– As a result EGR flow stops and a lean condition

occurs– HO2S voltage will drop– STFT sees HO2S voltage drop and increases IPW

– The PCM monitors STFT and EGR monitor is complete & Ready

13

Diagnostics With Mode 6 & 7

• Emission Test Failure or Readiness Monitor– Readiness Status– First checking for pending codes– Next review Datastream for errors– Perform Bi-directional test where applicable– Make repairs– Perform drive cycle to verify

14

Diagnostics With Mode 6 & 7

• MIL on – Check Diagnostic Trouble Code– Next review Datastream for errors– Perform Bi-directional test where

applicable– Make repairs– Perform drive cycle to verify– Verify Readiness Status

SCAN • Is the scan tool giving good information?• Does the sensor data match what the

voltmeter or lab scope displays?• Will the bi-directional confirm a

problem?• Does the command that the computer

uses make sense?• Always check grounds with a DVOM

because of sensor data allocation data.• Always check Voltage reference supply

to sensors.• Do sensors move in reaction to others?
