PINPOINT TEST 1: KEY-IN-IGNITION WARNING CHIME DOES NOT OPERATE CORRECTLY

Normal Operation
The key-in-ignition warning chime sounds when the driver door is opened with the key in the ignition lock cylinder, and the ignition switch is in the OFF or ACC position. It continues to sound until the key is removed from the ignition lock cylinder, or the driver door is closed. With the key inserted in the ignition lock cylinder, the key-in-ignition warning switch grounds the instrument cluster through circuit (B/P).

Possible Causes
- circuit (B/P) open or short to ground
- key-in-ignition warning chime
- instrument cluster

CAUTION: Use the correct probe adaptor(s) when making measurements. Failure to use the correct probe adaptor(s) may damage the connector.
