Main Relay Inspection

MAIN RELAY INSPECTION

Inspection of Output Voltage

1. Disconnect the PCM connector.




2. Connect the SST (104 Pin Breakout Box) to the PCM as shown.
3. Tighten the connector bolt.

Tightening torque: 7.9 - 10.7 N.m {80 - 100 kgf.cm, 69.5 - 95.4 in.lbf}

4. Turn the ignition switch to ON.

Specification:

5. Measure the voltage at PCM terminal 71 and 97.
- If not as specified, check the related harness and main relay continuity.

Inspection of Continuity

1. Remove the main relay.







2. Apply battery positive voltage and check continuity between terminals of the main relay using an ohmmeter.
- If not as specified, replace the main relay.
- If okay, inspect related harness and connectors.
