Removal Procedure

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.
