Electronic Brake Control Module Replacement (With JL4)

Removal Procedure

Caution: 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.




1. Turn the ignition switch to the OFF position.
2. Remove the cover from the engine control module (ECM) and transmission control module (TCM).
3. Clean the electronic brake control module (EBCM) to brake pressure modulator valve (BPMV) area of any accumulated dirt and foreign material.
