DIAGNOSIS PROCEDURE
STEP 1. MUT-II/III data list Item 23: Output shaft speed sensor (Refer to data list reference table ) <Except for Hong Kong spec.>. Item 02: Output shaft speed sensor (Refer to data list reference table ) <Vehicles for Hong Kong spec.>. Q: Is the check result normal? YES: Go to Step 2. NO: Refer to diagnosis code 23: Output shaft speed sensor system <4G63, 4G64>, <4G69>.
STEP 2. MUT-II/III data list Item 11: Throttle position sensor (Refer to data list reference table ). Q: Is the check result normal? YES: Go to Step 3. NO: Check the throttle position sensor system (Refer to GROUP 13A, Troubleshooting <4G63>, GROUP 13B, Troubleshooting <4G64>, GROUP 13C, Troubleshooting , <4G69>).
STEP 3. MUT-II/III actuator test Item 14: INVECS-II cancel command. Test drive the vehicle (Refer to Road Test, Inspection procedure 8 ).
