INJECTOR SOLENOID VALVE DRIVING SYSTEM GND SHORT-CIRCUIT












1. CHECK THE RESISTANCE BETWEEN TERMINALS.
1. Set the starter switch to "LOCK" and connect the signal check harness.
2. Disconnect the signal check harness connector on the ECU side.
3. Measure the resistance between the terminals of ECU connector (vehicle harness side).







Standard : infinite ohms












4. Turn the starter switch to "LOCK" position. Reconnect all the connectors.
5. Start the engine and erase the DTC.
6. If the same DTC is displayed, replace ECU. If no DTC is displayed, a temporary failure would have occurred.
7. Turn the starter switch to "LOCK" position (with all connectors of ECU disconnected).
8. Disconnect the injector connector that is located on the front side of the cam housing.







9. Measure the resistance between the pins of injector connector (vehicle harness side) and ECU case GND.

NOTICE:
- Measure the voltage of this connector from the connector terminals (female).
- Do not damage the connector terminals.







Standard: infinite ohms
