CHIMES CONTINUE WHEN HEADLAMPS ARE
TURNED OFF AND/OR KEY IS REMOVED FROM
IGNITION
(1) Use DRB III
scan tool to perform PCI data
bus diagnostics on BCM for headlamp or key-in-igni-
tion inputs.
(2) Check wiring for a grounded condition between
key-in switch and BCM. Check headlamp switch to
BCM wiring for short to battery.
(3) Inspect BCM connectors and wires for proper
connection.
DIAGNOSIS AND TESTING - EXTERIOR LAMPS
LEFT ON
To test the headlamps left on function, turn igni-
tion off, turn exterior lamps on with driver's door
open. Chime should sound until headlamps are
turned off or drivers door is closed.
DIAGNOSIS AND TESTING - KEY LEFT IN
IGNITION SWITCH
To test the key left in ignition function:
• The ignition switch must be in the OFF position
with key in ignition.
• Driver's door open.
• Chime should sound until key is removed from
ignition or drivers door is closed.
DIAGNOSIS AND TESTING - FASTEN SEAT
BELTS
To test, the ignition switch must be in the OFF
position before testing the fasten seat belts. Turn the
