For 1990-2009 cars only
DTC Parameters
| • | Ignition in RUN position |
| • | ACC circuit 43 shorted-to-ground or open |
| • | Engine run flag present (engine running) |
| • | All conditions for greater than 30 seconds |
Diagnostic Aids
| • | The 30-second timer has been added to avoid false diagnostic code setting if the vehicle had experienced an extremely long crank condition. Maximum recommended crank time is 15 seconds to avoid damaging the starter. |
| • | Check for a poor connection at the BCM. Inspect the harness connectors for backed out terminals, improper terminal mating, broken connector locks, improperly formed or damaged terminals, and poor terminal-to-wire connection, terminal crimped over wire insulation and not conductors. |
| • | Inspect the wiring harness for damage. Check for broken or chaffed insulation. |
| • | If the fault is suspected to be intermittent, wiggling the harness wiring may help in locating the fault. |
