1. With the battery connected, remove the blown fuse.
2. Connect the short finder between the positive battery terminal and the load side fuse terminal.
3. Close all switches in series with the wire that you are troubleshooting.
4. Turn on the short finder This will send pulses of current to the short and create a pulsing magnetic field around the wiring between the fuse box
and the short.
5. Beginning at the fuse box, slowly move the short finder meter along the circuit wiring. The meter will show current pulses through sheet metal and
body trim. As long as the meter is between the fuse and the short, the needle will move with each current pulse. Once you move the meter past the
point of the short, the needle will stop moving. Check around this area to locate the cause of the short circuit.

Wiring Harness Service
The control module harness electrically connects the control module to the various solenoids, switches and sensors in the vehicle engine compartment
and passenger compartment.
Replace wire harnesses with the proper part number replacement.
Because of the low amperage and voltage levels utilized in powertrain control systems, it is essential that all wiring in environmentally exposed areas be
repaired with crimp and seal splice sleeves.
The wire harness repair information is intended as a general guideline only. Refer to Wiring System Diagnositc Aids for all wire harness repair
procedures.
