HCU Passes inspection – Proceed to Valve Activation PASSES IDS Routine, on Page 9.

HCU Replacement Not Required.

HCU DOES NOT PASS inspection – Proceed to Valve Activation FAILS IDS Routine, on Page 14.

This procedure will include the HCU Replacement procedure, and Brake Fluid Change Procedure.

 

Valve Activation PASSES IDS Routine

NOTE: DOT3 Brake fluid should have previously been flushed from vehicle when completing 19S54 or 20S14. Updated DOT4 Brake Fluid reservoir cap should already be installed. Contact the SSSC if these are not present on vehicle and programs were previously completed.

 

Brake Fluid Change Procedure

1. With the vehicle in NEUTRAL, position it on a hoist. Please follow the Workshop Manual (WSM)
procedures in section 100-02.

NOTE: The front and rear wheel tire assemblies will remain on the vehicle while bleeding the brake calipers.

2. Bleed the brakes. Please follow WSM procedures in Section 206-00.

3. Using a suitable Brake/Clutch System Pressure Bleeder/Filler, such as the Flo-Dynamics® BrakeMate JR™ brake flush machine, install the bleeder adapter to the brake master cylinder reservoir and attach the bleeder tank hose to the fitting on the adapter.

NOTE: When using a suitable Brake/Clutch System Pressure Bleeder/Filler ensure that you are using the correct adapter cap. The cap should fit tight/snug on the brake master cylinder reservoir. To ensure a proper fit to the brake master cylinder while using the power bleeder, it is recommend to use adapter 199-40100045 available through Rotunda or adapter BA04 SP available through NORCO INDUSTRIES©. The cap can be manually adjusted and tightened by moving the bands of the cap with your hands to further ensure a proper fit. See Figure 12.

 

4. Turn off the pressure bleeding machine and remove the adapter cap from the master cylinder reservoir – The pressure bleeder will be used one last time for a final bleed after the next step (IDS Routine).

5. Verify the brake system connections are secure and functioning properly (master cylinder cap, bleeder screws, etc.) prior to performing the IDS Routine.

NOTICE: The Integrated Diagnostic Software (IDS) ABS service bleed procedure must be performed.

6. Select the “Tool Box” tab then “Chassis”, “Braking” then “ABS Service Bleed”. See Figure 13.

7. Follow the on screen prompts to complete the procedure.

NORMAL OPERATION

The operating voltage required to supply the hydraulic pump motor is in a range between 10 and 16 volts. Fused battery voltage for the hydraulic pump is supplied to the ABS module from Battery Junction Box (BJB) fuse 8 (40A) SBB08 (VT/RD) along circuit SBB08 (VT/RD). Ground for the hydraulic pump is provided through the ABS module along circuit GD123 (BK/GY).

DTC C1095 (ABS Hydraulic Pump Motor Circuit Failure) — If the ABS module detects an open circuit, a short to voltage or ground or a defective internal power transistor during normal operation or the ABS module self-test, DTC C1095 will be set. The ABS module will command the pump motor ON for 100 ms (±6 ms), then command the motor OFF and measure the voltage produced by the motor after 6 ms. If the voltage indicates that the motor is spinning at less than 500 rpm, there may be a locked motor. If this condition is detected 4 times, then DTC C1095 will be set. The pump motor is also checked for an open circuit 2 seconds after the most recent successful pump motor off command. If the pump motor feedback remains greater than 0.75 volt for more than 50 ms (±6 ms) after these conditions have been met, then DTC C1095 will be set.
