Special Tools
EL 39200 - Digital Multimeter (DMM)
For equivalent regional tools, refer to Special Tools (See: Power and Ground Distribution/Tools and Equipment).
Caution: Refer to Test Probe Caution (See: Service Precautions/Vehicle Damage Warnings/Test Probe Caution).
The following procedures verify good continuity in a circuit.
With a Digital Multimeter (DMM)
1. Set the rotary dial of the DMM to the Ohms position.
2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit.
3. Disconnect the load.
4. Press the MIN MAX button on the DMM.
5. Connect one lead of the DMM to one end of the circuit to be tested.
6. Connect the other lead of the DMM to the other end of the circuit.
7. If the DMM displays low or no resistance, the circuit has good continuity.
With a Test Lamp
Note: Only use the test lamp procedure on low impedance power and ground circuits.
1. Remove the power feed (i.e. fuse, control module) from the suspect circuit.
2. Disconnect the load.
3. Connect one lead of the test lamp to one end of the circuit to be tested.
4. Connect the other lead of the test lamp to battery positive voltage.
5. Connect the other end of the circuit to ground.
6. If the test lamp illuminates (full intensity), then the circuit has good continuity.

Perform the following procedures while wiggling the harness from side to side. Continue this at convenient points (about 6 inches apart) while watching
the test equipment.

If the fault is not identified, perform the procedure below using the MIN MAX feature on the EL-39200 DMM. This feature allows you to manipulate the
circuit without having to watch the EL-39200. The EL-39200 will generate an audible tone when a change is detected.
Note: The EL-39200 must be used in order to perform the following procedure since the EL-39200 can monitor current, resistance or voltage while
recording the minimum (MIN), and maximum (MAX) values measured.
1. Connect the EL-39200 to both sides of a suspected connector (still connected), or from one end of a suspected circuit to the other. Refer to
