1. CHECK DLC3


NOTICE: *: Before measuring the resistance, leave the vehicle as is for at least 1 minute and do not operate the ignition switch, any other switches, or the doors.
If the result is not as specified, the DLC3 may have a malfunction. Repair or replace the harness and connector.
HINT: If the display shows an error message after having connected the cable of the intelligent tester to the DLC3, turned the ignition switch to the ON position, and operated the tester, there is a problem on either the vehicle side or the tool side.

DESCRIPTION
The ECM monitors the output voltage to the throttle actuator. This self-check
ensures that the ECM is
functioning properly. The output voltage is usually 0 V when the ignition switch
is turned off. If the output
voltage is higher t ...

1. INSPECT THROTTLE BODY
Listen to the throttle control motor operating sounds.
Turn the ignition switch to the ON position.
When pressing the accelerator pedal position
sensor lever, listen to the running motor. Make
