Mechanical - Engine coolant leaks
- Engine oil leaks
- Fuel leaks
- Damaged or severely worn parts
- Loose mounting bolts, studs and nuts
- If the inspection reveals obvious concerns that can be readily identified, repair as necessary.
- If the cause is not visually evident, connect the scan tool to the data link connector (DLC).
- If the scan tool does not communicate with the VCM:
- check the VCM connection to the vehicle.
- check the scan tool connection to the VCM.
- refer to MODULE COMMUNICATIONS NETWORK , No power to the scan tool, to diagnose no communication with the scan tool.
- If the scan tool does not communicate with the vehicle:
- verify the ignition key is in the ON position.
- verify the scan tool operation with a known good vehicle.
- refer to MODULE COMMUNICATIONS NETWORK to diagnose no response from the powertrain control module (PCM).
- Carry out the network test.
