PINPOINT TEST A: THE KEY-IN-IGNITION WARNING CHIME IS INOPERATIVE/DOES NOT OPERATE CORRECTLY

A1-A4:

A5-A6:

Normal Operation
When the key is inserted into the ignition lock cylinder, the key-in-ignition warning switch (part of the ignition lock cylinder) grounds circuit 158 (BK/PK). The ground input signals the instrument cluster the key is inserted. If the instrument cluster detects that the ignition switch is in the OFF or ACC position with the key inserted in the ignition lock cylinder and the driver door is ajar, the key-in-ignition warning chime sounds.

Possible Causes
- circuit 158 (BK/PK) open or short to ground
- key-in-ignition warning switch (part of the ignition lock cylinder)
- instrument cluster
