Electronic Brake Control Module (EBCM) Replacement
Removal Procedure
NOTICE: Always connect or disconnect the wiring harness 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 the OFF mode only, before disconnecting the negative battery cable during this procedure. If the ignition
switch is accidentally placed into ignition ON engine OFF mode, the control modules will be activated and disconnecting the negative battery cable
will cause various DTCs to be set.
-After the ignition switch is placed into the OFF mode, a waiting period of two minutes must be observed to allow the high-speed LAN control
modules to deactivate before disconnecting or connecting the negative battery cable during this procedure. If the waiting period is not observed, one
or more of these control modules may still be active, this will cause various DTCs to be set.
1. Turn the ignition switch to the OFF position. Do NOT place the ignition switch into ignition ON engine OFF position.
2. Wait for a minimum of two minutes to allow the high-speed LAN control modules to deactivate.
3. Disconnect the negative battery cable.
4. Thoroughly clean the electronic brake control module (EBCM) to brake pressure modulator valve (BPMV) area of any dirt or contaminants.
5. Raise and suitably support the vehicle.
6. Remove the two BPMV bracket-to-crossmember mounting bolts to improve access to the EBCM and connector.
7. Support the ABS modulator assembly.
8. Disconnect the electrical connector from the brake fluid pressure sensor.
