For 1990-2009 cars

### Circuit Description

When the ignition key is seated in the ignition switch, the key-in-ignition switch contacts the close, grounding circuit 80. The body control module (BCM) monitors the state of the key-in-ignition switch, the state of the ignition switch (OFF, ACC, or RUN) and the driver's door to control the key-in-ignition chime.

### Conditions for Setting the DTC

• | Ignition in the RUN position

• | Circuit 80 open

• | Conditions exist for 1 second

• | Telltale will illuminate

### Diagnostic Aids

• | 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 the wire insulation and not the conductors).

• | Inspect the wiring harness for damage. Check for broken or chaffed insulation.

• | Check for a poor connection at the ignition switch.

• | If the fault is suspected to be intermittent, wiggling the harness wiring may help in locating the fault.

• | You will not hear the key in ignition chime if you leave key in ignition (after rotating ignition switch) and the driver door is open.
