Vehicle Does Not Creep Backward in “R” PositionBCS0014E
SYMPTOM:
Vehicle does not creep backward when selecting “R” position.
DIAGNOSTIC PROCEDURE
1. CHECK A/T FLUID LEVEL
Check A/T fluid level. Refer to AT- 1 4 , "
Checking A/T Fluid" .
OK or NG
OK >> GO TO 2.
NG >> Refill ATF.
2. CHECK LINE PRESSURE
Check line pressure at idle with selector lever in “R” position. Refer to AT- 4 6 , "
LINE PRESSURE TEST" .
OK or NG
OK >> GO TO 4.
NG >> GO TO 3.
3. DETECT MALFUNCTIONING ITEM
1. Remove control valve assembly. Refer to AT- 2 2 5 , "
Control Valve Assembly and Accumulators" .
2. Check the following items:
–Valves to control line pressure (Pressure regulator valve, pressure modifier valve, pilot valve and pilot fil-
ter)
–Line pressure solenoid valve
3. Disassemble A/T. Refer to AT- 2 5 5 , "
Disassembly" .
4. Check the following item:
–Oil pump assembly. Refer to AT- 2 7 5 , "Oil Pump" .
OK or NG
OK >> GO TO 4.
NG >> Repair or replace damaged parts.
4. CHECK STALL REVOLUTION
Check stall revolution with selector lever in “1” and “R” positions. Refer to AT- 4 3 , "
STALL TEST" .
OK or NG
OK >> GO TO 6.
OK in “1” position, NG in “R” position>> GO TO 5.
NG in both “1” and “R” positions>> GO TO 7.
5. DETECT MALFUNCTIONING ITEM
1. Disassemble A/T. Refer to AT- 2 5 5 , "
Disassembly" .
2. Check the following items:
–Low & reverse brake assembly. Refer to AT- 3 1 5 , "Low & Reverse Brake" .
–Reverse clutch assembly. Refer to AT- 2 9 6 , "Reverse Clutch" .
OK or NG
OK >> GO TO 6.
NG >> Repair or replace damaged parts.

TROUBLE DIAGNOSIS FOR SYMPTOMS

6. CHECK A/T FLUID CONDITION
1. Remove oil pan. Refer to AT- 2 4 6 , "
Components" .
2. Check A/T fluid condition. Refer to AT- 4 3 , "
A/T Fluid Condition Check" .
OK or NG
OK >> GO TO 8.
NG >> GO TO 7.
7. DETECT MALFUNCTIONING ITEM
1. Disassemble A/T. Refer to AT- 2 5 5 , "
Disassembly" .
2. Check the following items:
–Reverse clutch assembly. Refer to AT- 2 9 6 , "Reverse Clutch" .
–High clutch assembly. Refer to AT- 3 0 1 , "High Clutch" .
–Low & reverse brake assembly. Refer to AT- 3 1 5 , "Low & Reverse Brake" .
–Forward clutch assembly. Refer to AT- 3 0 7 , "Forward and Overrun Clutches" .
–Overrun clutch assembly. Refer to AT- 3 0 7 , "Forward and Overrun Clutches" .
OK or NG
OK >> GO TO 8.
NG >> Repair or replace damaged parts.
8. SYMPTOM CHECK
Check again. Refer to AT- 4 8 , "
Check at Idle" .
OK or NG
OK >>INSPECTION END
NG >> GO TO 9.
9. CHECK TCM
1. Check TCM input/output signals. Refer to AT- 6 4 , "
TCM Terminals and Reference Value" .
2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector.
OK or NG
OK >>INSPECTION END
NG >> Repair or replace damaged parts.
