Disconnect the 4 connectors with wire harness locks from the 2 injector drivers.
HINT:
- To release each connector lock, push the claw downward ("Release" in the illustration) and move the lock lever ("Move" in the illustration).
- Perform this step to prevent the engine from starting.
Remove the engine room ECU cover (See REMOVAL ).
Turn the engine switch on (IG).
HINT.

Do not start the engine.

Measure the voltage according to the value(s) in the table below.
