Removal Procedure
1. Remove the power steering fluid reservoir and bracket.
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.
Turn the ignition switch to the OFF position. Do NOT put the ignition switch into the ON with engine OFF power mode.
2. Wait for a minimum of 2 minutes to allow the high-speed LAN control modules to deactivate.
3. Disconnect the electronic brake control module EBCM harness connector.
4. Remove the brake pressure modulator valve (BPMV) pump motor ground wire.
5. Remove the brake pipes from the master cylinder to the BPMV (1, 2), noting the location.
6. Remove the brake pipes from the BPMV (1, 2) to the front brake calipers, noting the location.
