NO.1 VEHICLE DOES NOT MOVE IN D RANGE, OR IN R POSITION
1 Vehicle does not move in D range, or in R position
• Vehicle does not move when accelerator pedal depressed.
DESCRIPTION
• If vehicle does not move in D range or R position, basically, malfunction is in ATX. (Vehicle will move
even with a malfunction in TCM.) Since a malfunction in sensor circuit or output circuit is cause of
malfunction in ATX, inspect sensors, output circuit, and related harnesses.
— Clutch slipped, worn (D range-Low clutch, Low one-way clutch, Reduction one-way clutch, R
POSSIBLE
CAUSE
— Malfunction of selector lever
— Parking mechanism not properly operated
— Malfunction of torque converter

and engine off, does vehicle move when
pushed? (in D ranges or N, R positions and
brake released)
• Start engine.
2
• Does vehicle move when selector lever in
between N position and D range?
• Stop engine.
3
• Inspect pressure control solenoid circuit.
• Is it okay?
• Verify test results.

— If okay, return to diagnostic index to service any additional symptoms.
— If malfunction remains, inspect related Service Informations and perform repair or diagnosis.
— If vehicle repaired, troubleshooting completed.
— If vehicle not repaired or additional diagnostic information not available, replace TCM.

NO.2 VEHICLE MOVES IN N POSITION
2 Vehicle moves in N position
• Vehicle creeps in N position.
DESCRIPTION
• Vehicle creeps if brake pedal not depressed in N position.
• If vehicle moves in N position, basically, malfunction is in ATX. Since a malfunction in sensor circuit or
output circuit is cause of malfunction in ATX, inspect sensors, output circuit, and related harnesses.
— Clutch burned (Low clutch, Low one-way clutch, Low and reverse brake)
