Gear 1 Off On Off On Off
Gear 2 On Off Off On On
Gear 3 On Off Off Off On
Gear 4 On Off On Off On
Reverse gear OffOnOnOn Off
Neutral gear/
Parking OffOnOnOn Off
Is the check result normal?
Ye s>>The condition that caused this DTC is intermittent (See Diagnostic Help in Section 08 Transaxle &
Transfer Case).
No
>>Go to the next step.
2.ACTUATE TEST
