(a)
Check APP sensor harness connector IP50 terminal No.6
output voltage. For the Standard Value. Refer to
2.12.7.13 Acceleration Pedal Position Sensor (APP)
Is the output voltage Standard Value?
No
Yes
(a)
Turn the ignition switch to "OFF" position.
(b)
Disconnect APP sensor harness connector IP50.
