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), overrun clutch solenoid valve, torque converter clutch solenoid valve, 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 P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVE ", "DTC P0750 SHIFT SOLENOID VALVE A ", "DTC P0755 SHIFT SOLENOID VALVE B ", "DTC P1760 OVERRUN CLUTCH SOLENOID VALVE " or "DTC VHCL SPEED SEN.MTR VEHICLE SPEED SENSOR.MTR ".
   2. No: GO TO 3.

3. CHECK THROTTLE POSITION SENSOR [ACCELERATOR PEDAL POSITION (APP) SENSOR] 

   Check throttle position sensor [accelerator pedal position (APP) sensor]. Refer to DTC P0122, P0123: TP SENSOR ".

   OK or NG 

   1. OK: GO TO 4.
   2. NG: Repair or replace throttle position sensor [accelerator pedal position (APP) sensor].

4. CHECK LINE PRESSURE 

   Check line pressure at stall point with selector lever in "D" position. Refer to "LINE PRESSURE TEST ".

   OK or NG 

   1. OK: GO TO 5.
   2. NG: GO TO  8.

5. CHECK A/T FLUID CONDITION 
   1. Remove oil pan.
   2. Check A/T fluid condition.

   OK or NG 

   1. OK: GO TO 6.
   2. NG: GO TO  8.

6. DETECT MALFUNCTIONING ITEM 
   1. Remove control valve assembly. Refer to "REMOVAL ".
   2. Check the following items:
      • Shift valve A
      • Shift valve B
      • Shift solenoid valve A
      • Shift solenoid valve B
      • Pilot valve
      • Pilot filter

   OK or NG 

   1. OK: GO TO 7.
   2. NG: Repair or replace damaged parts.
7. CHECK SYMPTOM 

   Check again.

   OK or NG 

   1. OK: INSPECTION END 
   2. NG:
      1. Perform TCM input/output signal inspection. See INPUT/OUTPUT SIGNAL OF TCM .
      2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector.
8. DETECT MALFUNCTIONING ITEM 
   1. Remove control valve assembly. Refer to "REMOVAL ".
   2. Check the following items:
      • Shift valve A
      • Shift valve B
      • Shift solenoid valve A
      • Shift solenoid valve B
      • Pilot valve
      • Pilot filter
   3. Disassemble A/T.
   4. Check the following items:
      • High clutch assembly
      • Torque converter
      • Oil pump assembly
      • Reverse clutch assembly
      • Low and reverse brake assembly

   OK or NG
