Removal Procedure
- Remove the power steering fluid reservoir and bracket. Refer to Remote Power Steering Fluid Reservoir Replacement .
- Turn the ignition switch to the OFF position. Do NOT put the ignition switch into the ON with engine OFF power mode.
- Wait for a minimum of 2 minutes to allow the high-speed LAN control modules to deactivate.
- Disconnect the EBCM harness connector.
- Remove the brake pressure modulator valve (BPMV) pump motor ground wire.
- Remove the brake pipes from the master cylinder to the BPMV (1, 2), noting the location.
- Remove the brake pipes from the BPMV (1, 2) to the front brake calipers, noting the location.
- Remove the brake pipes from the BPMV (1, 2) to the rear brake calipers, noting the location.
- Disconnect the electrical connector from the brake fluid pressure sensor (2).
- Remove the two insulator nuts (1).
- Remove the EBCM/BPMV from the vehicle as one unit.
- Remove the insulator mounting bolt from the EBCM.
- Remove the four EBCM to BPMV bolts.
- Separate the EBCM from the BPMV by gently pulling apart until separated.
- Carefully remove the seal.
Notice: Always connect or disconnect the wiring harness connector from the EBCM/EBTCM with the ignition switch in the OFF position. Failure to observe this precaution could result in damage to the EBCM/EBTCM.
Important:
• The ignition switch must be placed in OFF mode ONLY, before disconnecting the electronic brake control module (EBCM). If the ignition is accidently placed into ignition ON engine OFF mode, the control modules will be activated and disconnecting the
module or negative battery cable will cause various DTCs to be set. Refer to
Keyless Entry System Description and Operation
. • After the ignition switch is placed into OFF mode, a waiting period of 2 minutes must be observed to allow the high-speed LAN control modules to deactivate before disconnecting or connecting the module or negative battery cable. If the waiting
period is not observed, one or more of the control modules may still be active; this will cause various DTCs to be set.
The seal may be reused if it is not cut or damaged.
Installation Procedure
- Clean the BPMV seal surface with alcohol using a clean rag.
- Install the seal to the BPMV, if it is not cut or damaged.
- Install the EBCM to the BPMV.
- Install the 4 EBCM-to-BPMV bolts. Tighten in a criss-cross pattern.
- Install the EBCM/BPMV insulator mounting bolt.
- Install the EBCM/BPMV into the bracket on the vehicle.
- Install the two insulator nuts (1).
- Connect the brake fluid pressure sensor electrical connector (2).
- Install the brake pipe fittings from the rear brake calipers (1, 2) to the BPMV in the same location as removed.
- Install the brake pipe fittings from the front brake calipers (1, 2) to the BPMV in the same location as removed.
- Install the brake pipe fittings from the master cylinder (1, 2) to the BPMV in the same location as removed.
- Connect the BPMV pump motor ground.
- Connect the EBCM harness connector.
- Install the power steering fluid reservoir and bracket. Refer to Remote Power Steering Fluid Reservoir Replacement .
- Bleed the hydraulic brake system. Refer to Hydraulic Brake System Bleeding .
- Bleed the antilock brake system. Refer to Antilock Brake System Automated Bleed Procedure .
- Perform the Diagnostic System Check - Vehicle .
Important: When installing a new BPMV, do NOT remove the shipping plugs from the outlets until after installation into the vehicle.
Notice: Refer to Fastener Notice in the Preface section.
