NOTE: The following instructions assume that the

vehicle already has a Fleece Performance Engineering

2nd gen kit installed on the vehicle along with an S400

turbo with appropriate 4 5/8” OD flat V turbo outlet

flange. The exhaust manifold must be the downward

direction.

NOTE: If your 2nd gen kit is of an older vintage, you

may NOT have installed a coolant riser delete

originally with your kit. A coolant riser delete is

required for use with this kit. NEW 2nd gen hardware

kits available from Fleece Performance include the

coolant riser delete kit.

STEP 1: Drain engine coolant and remove the

passenger side front inner fender well.

STEP 2: Remove the originally installed FPE exhaust

downpipe from the turbo housing and exhaust

system.

STEP 3: Assemble the exhaust brake valve to the cast

elbow using a V-band (item 4). Based on your turbo,

alignment pins on the cast elbow may be used or

removed by using a pair of pliers to pull the pin

outward. Not all turbos are configured to allow for

use of the dowel pin.

Install the two M12 x 1.0 inverted flare plugs onto

either side of the exhaust brake housing. These two

ports are unused BUT CAN be used for a back-

pressure sensor if desired for monitoring back-

pressure. Remove the two red plug caps for the

cooling ports and install the two -6 to 9/16”-18

straight male w/ O-ring fittings onto the exhaust

brake cooling ports.

STEP 4: Install the exhaust brake valve and cast elbow

to the discharge of your turbocharger using a V-band

clamp (item 4).

PROCEDURE:

STEP 5: Locate the coolant port on the engine block

located to the front of the oil filter housing that

supplied the factory VGT turbo with coolant. Remove

the installed block off plug (typically a socket allen

head) and install the appropriate -6AN fitting and

sealing washer for your engine. Two sizes are provided

in the kit, a 18mm and a 16mm - you will only use one.

STEP 6: Install the coolant riser delete hoses IF

REQUIRED. Reference our installation instructions for

the coolant riser delete kits on our website or by

clicking here. Select a location just to the rear of your

battery box to cut-in the ⅝ to ⅜ adapter tee and hose

based upon your routing. The location will depend

upon how you have routed your coolant line from

the riser to the firewall.

If the truck already has a Fleece coolant riser delete

installed or an after-market coolant tank, install the

⅝” to ⅜” adapter tee and hose at any point in the

hose that works best for your routing. The image to

the right shows the new adapter tee for the exhaust

brake installed between the coolant tank and coolant

riser delete adapter tee.

STEP 7: Install the -6 AN hose (item 13) provided with

the 45 deg fitting to the engine block and the 120 deg

fitting to the front port on the exhaust brake.

Next, install the hose from the adapter tee to the

rear port of the exhaust brake using the 90 deg

fitting.

STEP 8: Install the lower portion of the downpipe

back into your existing exhaust, attach the downpipe

to the cast elbow with a V-band clamp (item 4).

STEP 9: Plug the exhaust brake’s electrical connector

into the OEM’s original VGT connector. Plug the

other end into the pigtail on the exhaust brake. This

connection provides 12v power to the actuator.

Reference page 10 for an electrical harness diagram. STEP 10: Route the two wire CAN signal along the top of the engine bay, securing it to the firewall or existing OEM cable looms. Cut a slit in the firewall cable pass-through located to the right of the steering column (as viewed from the engine bay). Route the two-wire CAN signal line through the firewall pass-though and plug the CAN signal connector into the OEM communication junction block. It will contain green two-pin receptacles. You can use any open port on the junction block that contains yellow wires. You must use the CAN block that contains the yellow wires – the other CAN block with white wiring will not work. If you choose the incorrect CAN block, the engine will not start and DTC’s will be present.

The CAN communication junction block is located

directly under the dash on the driver’s side,

immediately to the left of the steering column and

above the clutch pedal vicinity.

STEP 11: Refill coolant and check for leaks. Re-install

the inner fender well. If removed, re-install any intake

components and connect all sensors.

STEP 12: Operate the vehicle and activate the exhaust

brake switch on your dash.

*Test for proper operation of the exhaust brake as

outlined in “OPERATING MODES AND CONDITIONS”

below.

*Verify coolant flow through the brake assembly by

loosening a fitting at the brake and allowing coolant to

seep. If coolant flow is not present, check coolant level

and line routings.

EXHAUST BRAKE OPERATING MODES AND CONDITIONS

COLD START WARMUP MODE: The exhaust brake will partially close when the following conditions are present to assist

in faster engine warmup.

• Engine coolant temperature less than 150F

• Engine RPM greater than 550 RPM

• Vehicle speed less than 2 mph

• Throttle position equal to 0%

Cold start warmup mode will be disabled if any of the above conditions are not met and will resume if all conditions are

re-met. i.e. – pressing on the throttle will disable cold start warmup mode, releasing the throttle with all conditions

present will allow the brake to return to cold start warmup mode. Cold start warmup mode is always active regardless of

exhaust brake switch position.

FULL-ON MODE: This mode provides for the fastest response time from the brake. “Full Exhaust Brake On” will be

displayed on the dash when selected with the OEM dash switch. The exhaust brake will close when the following

conditions are present for ½ second:

• Throttle = 0%

• ABS is inactive (exhaust brake will not function if any ABS fault or

condition is present)

• Engine RPM greater than 800

• Vehicle speed greater than 10 mph

• Cruise control is not set

• Clutch is not depressed (manual transmission only)

AUTO MODE: This mode will not activate the exhaust brake until the service brake is depressed. “Automatic Exhaust

Brake On” will be displayed on the dash when selected with the OEM dash switch. The exhaust brake will close when the

following conditions are present for ½ second:

• Throttle = 0%

• Service brake is applied

• ABS is inactive (exhaust brake will not function if any ABS fault or

condition is present)

• Engine RPM greater than 800

• Vehicle speed greater than 10 mph

• Cruise control is not set

• Clutch is not depressed (manual transmission only)

TROUBLESHOOTING

SYMPTOM POSSIBLE CAUSES Exhaust brake operates in cold start warmup mode but not during driving or when warmed up.

Manual transmission equipped trucks: The clutch switch has failed or has an intermittent connection and is not toggling between active/inactive states. The truck will start and no DTC’s will be logged when a failed clutch switch occurs. You can view the “Clutch Status” with a scan tool to confirm proper operation, it should toggle between “engaged” and “disengaged”. ABS status: Ensure that ABS is “Inactive”. Ensure coolant lines are properly routed and coolant flow is present by loosening a coolant port connection at the brake. Insufficient or no coolant flow will result in a brake that will not operate at high temperature due to lack of cooling.

Exhaust does not operate in any mode (cold start warmup or during driving).

Check all electrical connections and perform a tug test on the wiring. Ensure all pins are properly seated. Make sure all connections are tight. Confirm you have 12v power at the exhaust brake connection from the chassis/vehicle side. If you do not have 12v power, check your fuse panel. For MY13-18 trucks, 12v power is provided on the red wire (pin 4) and ground is supplied on the black wire (pin 1). High speed communication is on pins 2 & 3.

Intermittent exhaust brake operation during cold start warmup or during driving operation.

Check all electrical connections and perform a tug test on the wiring. Ensure all pins are properly seated. Make sure all connections are tight. Visually inspect all connectors for damaged or pushed pins or terminals.

Dash experiences erratic behavior, numerous DTC’s are present, or the truck will not start after installation of exhaust brake.

Incorrect high speed CAN port utilized. Remove CAN port connection and select the proper high speed CAN port on the truck. See step 10.
