Back - Up And Voltage Signal Circuit
KEY "OFF" POWER CIRCUIT
1. Using a Volt meter, check the Voltage between ECU harness terminal 103 and ground.
Voltage: ............................................................................................................................................................................................ System Voltage
2. Disconnect the negative battery cable and the ECU connector.
3. Using an Ohm meter, check for continuity between the positive battery terminal and ECU harness terminal 103.
Continuity: ............................................................................................................................................................................................ Should exist
4. Using an Ohm meter, check for continuity between chassis ground (not the negative battery terminal) and ECU harness terminal 103.
Continuity: ...................................................................................................................................................................................... Should not exist
