Ensure that the wiring harness assembly is correctly routed and the cable straps are not over tightened. Over tightening of the cable straps will damage the wiring harness and the convoluting.
The Electronic Control Module (ECM) can be a fuel cooled ECM or air cooled ECM. The installation procedure is similar for a fuel cooled ECM or air cooled ECM.
If a replacement ECM is installed, the replacement ECM must be programmed with the correct information. Refer to Troubleshooting Guide, "Replacing the ECM" and refer to Troubleshooting Guide, "Flash Programming" for the correct procedure.
Ensure that the electronic control module is clean and free from damage. If necessary, replace the electronic control module.
