Hydraulic Control Assembly - Antilock Brakes: Service and Repair

Brake Pressure Modulator Valve Replacement

Removal Procedure
Caution: Refer to Brake Fluid Irritant Caution (Brake Fluid Irritant Caution) .

Notice: Refer to Brake Fluid Effects on Paint and Electrical Components Notice (Vehicle Damage Warnings) .


Notice: To prevent equipment damage, never connect or disconnect the wiring harness connection from the EBCM with the ignition switch in the ON position.


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 cable will cause various DTCs to be set. Refer to Keyless Entry System Description and Operation (without RPO Y41) (Keyless Entry System Description and Operation (without RPO Y41))Keyless Entry System Description and Operation (with RPO Y41) (Keyless Entry System Description and Operation (with RPO Y41)) .

* 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 negative battery cable during this procedure. If the waiting period is not observed, one or more of these control modules may still be activated, causing various DTCs to be set.
