Signal Missing. Intermittent Fault
Checking Cables And Terminals
- Check engine cooling fan (FC) relay and engine control module (ECM) connectors for loose connections, contact resistance and oxidation.
- Check cable between engine cooling fan relay terminal B1and engine control module # A7 for an intermittent open-circuit.
- Check cable between engine cooling fan relay terminal A11 and starter motor for an intermittent open-circuit.
- Check cable between engine cooling fan relay connector B2 and engine control module # A22 for an intermittent short-circuit to ground.
Then proceed to test step below.
Fault-tracing Information
- For intermittent faults fault-tracing is not followed by a verification because the fault is not present at this moment.
- Do you want to repeat fault-tracing?
Yes:
