- Related electrical connectors or fuses
- Vacuum lines (leaks, routing)
- Air intake system (leaks, restrictions)
- Fuel quality (octane, contamination, winter/summer blend)
- Engine cooling system (engine operating at proper temperature)
- Motor electronics cooling system
- Access any related TSB information.
- Carry out the data link diagnostics test.
NOTE:
If the diagnostic tool being used does not support the data link diagnostics test, an alternative method is to attempt communication with each module on the CAN link.
Does the data link diagnostics test pass?
| Yes | No |
|---|---|
| GO to Quick Test QT2 . | If only the PCM and/or TCM have a communication concern: GO to Pinpoint Test QA . All others: Go to MODULE COMMUNICATIONS NETWORK to diagnose the network concern. |
