Faulty Signal. Intermittent Fault





Checking Cables And Terminals
- Check cable between Ignition Discharge Module (IDM) terminal 4 and engine control module (ECM) # B11 for an intermittent short-circuit to supply voltage.
- Check cable between fuel pump relay terminal 4 (31B) and engine control module # B27 for an intermittent short-circuit to supply voltage.
- Check cable between malfunction indicator lamp (MIL) terminal B11 in the combined instrument panel and engine control module # B7 for an intermittent short-circuit to supply voltage.
- Check cable between engine control module # B12 and transmission control module (TCM) # B12 for an intermittent short-circuit to supply voltage.
- Check cable between engine cooling fan (FC) relay terminal B2 and engine control module # A22 for an intermittent short-circuit to supply voltage.
