Component Inspection
Inspection of ContinuityNOTE: Perform the following test only when directed.
1. Disconnect the negative battery cable.
2. Remove the main relay.
3. Inspect for continuity between terminals of the relay using an ohmmeter.
- If not as specified, replace the main relay and perform the "Circuit Open/Short Inspection".
4. Reconnect the main relay connector.
Circuit Open/Short Inspection
Open Circuit
- If there is no continuity, the circuit is open. Repair or replace the harness.
- Reference voltage circuit (Main relay connector terminal A and ignition switch (IG1) connector through common connector)
- Reference voltage circuit (Main relay connector terminal C and battery (B+ terminal) connector through common connector.)
- Ground circuit (Main relay connector terminal B and ground circuit through common connector.)
Short circuit
- If there is continuity, the circuit is shorted. Repair or replace the harness.
- Main relay connector terminal A and ignition switch (IG1) connector through common connector to ground.
- Main relay connector terminal C and battery (B+ terminal) through common connector to ground.
