Avalanche 4WD V8-5.3L (2011)
1. Set the Digital Multimeter (DMM) to the V (DC) position.
2. Connect the positive lead of the DMM to one point of the circuit to be tested.
3. Connect the negative lead of the DMM to the other point of the circuit.
4. Operate the circuit.
5. The DMM displays the difference in voltage between the 2 points.

For equivalent regional tools, refer to Special Tools See: Tools and Equipment.
Danger: This procedure should not be performed on high voltage circuits. Performing this procedure on high voltage circuits may result in
serious injury or death.
Note: Always be sure to reinstall the connector position assurance (CPA) and terminal position assurance (TPA) when reconnecting connectors or
replacing terminals.
Front probe
Disconnect the connector and probe the terminals from the mating side (front) of the connector.
Caution: Refer to Test Probe Caution See: Service Precautions/Vehicle Damage Warnings/Test Probe Caution.
Note: When probing female 0.64 terminals, it is important to use the correct adapter. There have been some revisions to the test adapter for 0.64
terminals. The proper adapter for 0.64 terminals is the J-35616-64B which has a gold terminal and a black wire between the base and tip. Failure to use
the proper test adapter may result in damage to the terminal being tested and improper diagnosis.
Note: The proper adapter for probing the terminals for fuses, relays, or diodes in an electrical center is J-35616-35. Using any other tool or adapter may
damage the terminal being tested.
Refer to the following table as a guide in selecting the correct test adapter for front probing connectors:
