NOTE:

Perform the following procedure only when directed.

Turn the ignition switch to the LOCK position.
Disconnect the negative battery cable.
Remove the fuel delivery pipe. (See FUEL INJECTOR REMOVAL/INSTALLATION .)
Disconnect the fuel injector connectors.
Measure the resistance of the fuel injector using a tester.

- If as specified but "Operation Test" is failed, carry out the "Circuit Open/Short Inspection". Inspect for open or short circuit.
