TROUBLESHOOTING [GF4A-EL]
Symptom Troubleshooting
1 VEHICLE DOES NOT MOVE IN D, 2 ,1 RANGES, OR IN R POSITION
TROUBLESHOOTING HINTS
If the vehicle does not move in D, 2, 1 ranges or R position, basically, the malfunction is in the automatic transaxle. (Vehicle
will move even with a malfunction in the PCM.) Since a malfunction in the sensor circuit or output circuit is the cause of the
malfunction in the automatic transaxie, inspect the sensors, output circuit, and the related harnesses.
© Clutch slippage, worn (D, 2, 1 ranges— Forward clutch, R position— Reverse clutch, Low and reverse brake)
• Line pressure low
• Malfunction of throttle position sensor (Disparity in setting sensor settings)
• Malfunction of vehicle speedometer sensor (Disparity in setting sensor settings)
• Malfunction of input/turbine speed sensor (Disparity in setting sensor settings)
• Malfunction of sensor ground (Disparity in setting sensor settings)
• Malfunction of shift solenoid A (Sticking)
• Malfunction of shift solenoid B (Sticking)
• Malfunction of shift solenoid C (Sticking)
• Malfunction of pressure control solenoid valve (Sticking)
• Malfunction of body ground
• Malfunction of manual valve (Poor operation, sticking)
• Malfunction of pressure regulator valve (Poor operation, sticking)
• Malfunction of pressure modifier valve (Poor operation, sticking)
• Malfunction of pilot valve (Poor operation, sticking)

STEP
INSPECTION
ACTION
1
W ith vehicle stopped on a flat, paused road
and engine off, does vehicle move when
pushed? (in D, 2 ranges or N, R positions and
brake released)
Yes Go to next step
No Check for parking mechanism
o ’ ATX workshop manual
2 Does vehicle move when selector lever is in
between N position and D range? Yes
Go to next step
No Inspect or adjust the selector lever
o - 0 5-18 SELECTOR LEVER INSPECTION,
ADJUSTMENT
3 Check the voltage at the following terminal of
the powertrain control module
tr 0 1 -40B POWERTRAIN CONTROL
MODULE (PCM) INSPECTION [KL]
• Pressure control solenoid signal
Is terminal voltage okay?
Yes Go to next step
No Repair or replace any defective parts
4 Check duty of pressure control solenoid

INSPECTION [GF4A-EL], Pressure
Control Solenoid Output Duty Inspection
Is duty okay?
Yes
Overhaul control valve body and repair or replace any
defective parts
tr ATX workshop manual
If problem remains, overhaul transaxle and repair or
replace any defective parts
tr ATX workshop manual
No Check the voltage at the following terminals of the
powertrain control module
tr 01-40B POWERTRAIN CONTROL MODULE (PCM)
