- Disconnect the inoperative headlamp ballast connector.
- Connect a test lamp between the appropriate locations:
• | For the left headlamp, between CKT 712 (YEL) and ground |
• | For the right headlamp, between CKT 312 (TAN/WHT) and ground |
- Move the headlamp switch to the HEAD position.

- Connect the test leads and the test adapters to a J 39200
digital multimeter (DMM).
- Connect the leads of the J 39200
DMM together.
- Set the J 39200
DMM to the Ohms scale.
- Record this value. Subtract this value from all resistance readings.
If the meter you are using has zeroing function, zero the meter.
- Disconnect the negative battery cable.
- Connect the J 39200
DMM to the appropriate locations:
• | For the left headlamp, between CKT 150 (BLK) and ground |
• | For the right headlamp, between CKT 250 (BLK) and ground |
Is the resistance less than the specified value?

- Replace the LT LOW fuse or the RT LOW fuse in the underhood fuse
block with a 10A fuse.
- Connect a fused jumper with at least a 25A fuse between the following
components:
• | For the left headlamp, between CKT 712 (YEL) and CKT 150
(BLK) |
• | For the right headlamp, CKT 312 (TAN/WHT) and CKT 250
