SERVICE INFORMATION
If a vehicle exhibits symptoms such as poor driveability, Check Engine light on, hard/no start condition, or no CONSULT interface, especially after a
replacement ECCS control module (new ECM) has been installed, it is critical to ensure that the ECM connector and the center retaining bolt are fully
seated.
This bulletin details the procedure for properly seating the harness connector when installing a replacement ECM.
CAUTION:
^
Before connecting or disconnecting the ECM harness, be sure to turn the ignition switch "OFF" and disconnect the battery negative cable.
^
Do not remove the clear plastic wire protector from the back of the ECM connector -- it's very difficult to reinstall without damaging the wires.
