8. Vehicle Cannot Be Started From D1

SYMPTOM: 

Vehicle cannot be started from D1 on Cruise test - Part 1. 

1. CHECK SYMPTOM 

   Is "6. Vehicle Does Not Creep Backward In R Position" OK?

   Yes or No

   1. Yes: GO TO 2.
   2. No: Go to "6. VEHICLE DOES NOT CREEP BACKWARD IN R POSITION ".
2. CHECK SELF-DIAGNOSTIC RESULTS 

   Does self-diagnosis show damage to vehicle speed sensor.A/T (revolution sensor), shift solenoid valve A, B or vehicle speed sensor.MTR after cruise test?

   Yes or No

   1. Yes: Check damaged circuit. Refer to "DTC P0720 VEHICLE SPEED SENSOR.A/T (REVOLUTION SENSOR) ", "DTC P0750 SHIFT SOLENOID VALVE A ", "DTC P0755 SHIFT SOLENOID VALVE B " or "DTC VEHICLE SPEED SENSOR MTR ".
   2. No: GO TO 3.
