Diagnostic procedure

STEP

INSPECTION

ACTION

1
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
• Has the FREEZE FRAME DATA been recorded on the repair order?

Go to the next step.
3
INSPECT LINE PRESSURE
• Perform the “Line Pressures Test”. (See MECHANICAL SYSTEM TEST [AW6A-EL, AW6AX-EL].)
• Is there any malfunction?
Yes
All ranges: Replace the oil pump, then go to Step 6.
Any ranges: Replace the control valve body, then go to Step 6.
No
Go to the next step.
4
INSPECT STALL SPEED
• Perform the “Stall Test”. (See MECHANICAL SYSTEM TEST [AW6A-EL, AW6AX-EL].)
• Is there any malfunction?
Yes
Replace the automatic transaxle, then go to Step 6.
No
Go to the next step.
5
INSPECT SOLENOID VALVE
• Inspect the following solenoid valves: (See SOLENOID VALVE INSPECTION [AW6A-EL, AW6AX-EL].)
― Shift solenoid A
― Shift solenoid B
― Shift solenoid C
• Is there any malfunction?
Yes
Replace malfunctioning part according to test result, then go to the next step.
No
Go to the next step.
6
VERIFY TROUBLESHOOTING OF DTC P0942:00 COMPLETED

• Clear the DTC using the M-MDS.
• Perform the following procedure to ensure that the DTC has been resolved:
1. Start the engine.
2. Warm up the engine and transaxle.
3. Drive the vehicle in D range and make sure that the gears shift smoothly from 1GR to 6GR.
• Is the same DTC present?
Yes
Replace the TCM, then go to the next step.
No
Go to the next step.
7
VERIFY NO DTC HAS BEEN PRESENTED
• Perform the “Reading DTCs Procedure”. (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [AW6A-EL, AW6AX-EL].)
