The Engine Control Module (ECM) (16) is bolted to a support bracket near the fuel filter. The support bracket mounts to the block with four capscrews and vibration isolators. A ground wire is fastened to the bracket. The other end of the wire is fastened to the engine block.
- Record any Diagnostic Trouble Codes (DTC's) found in the ECM.
To avoid possible voltage spike damage to the ECM, ignition key must be off, and both negative battery cables must be disconnected before unplugging ECM connectors.
- Disconnect both negative battery cables at both batteries.
- Remove the 50-way and 60-way connector bolts at the ECM. Note: The connector bolt is a female Allen head. As bolt is being removed, very carefully remove connectors from the ECM.
- Remove five ECM mounting bolts and remove ECM from vehicle.
