Transaxle Drive Cycle Test: Notes

SPECIAL TOOLS

Vehicle Communication Module (VCM) and Integrated Diagnostic System (IDS) software with appropriate hardware, or equivalent scan tool

NOTE: Always drive the vehicle in a safe manner according to driving conditions and obey all traffic laws.

After carrying out the Self Test, use the following Transaxle Drive Cycle Test for checking continuous codes.

NOTE: The Transaxle Drive Cycle Test must be followed exactly. Malfunctions must occur 4 times consecutively for shift error DTCs to be set and 5 times consecutively for continuous Torque Converter Clutch (TCC) code to set.

NOTE: When carrying out the Transaxle Drive Cycle Test, see the Solenoid Operation Chart for correct solenoid operation. Refer to PINPOINT TESTS - OSC EQUIPPED VEHICLE .

Record and then erase Self Test codes.
Warm engine to normal operating temperature.
Make sure transmission fluid level is correct.
With transaxle in DRIVE, moderately accelerate from stop to 80 km/h (50 mph). This allows the transaxle to shift into 6th gear. Hold speed and throttle opening steady for minimum of 15 seconds.
With transaxle in 6th gear and maintaining steady speed and throttle opening, lightly apply and release brake (to operate stoplamps). Then hold speed and throttle steady for additional 5 seconds minimum.
Brake to a stop and remain stopped for minimum of 20 seconds.
Repeat Steps 4 through 6 at least 5 times.
Carry out Self Test and record continuous codes.

If DTCs are present, refer to DIAGNOSTIC TROUBLE CODE (DTC) CHARTS . Service all non-transaxle DTCs first as they can directly affect the operation of the transaxle. Repeat the Self Test and Road Test to verify the correction. Erase DTCs, carry out drive cycle, and repeat the Self Test after completing service on the DTCs.
If the continuous test passes (system pass) and a concern is still present, refer to DIAGNOSIS BY SYMPTOM check TSBs for diagnostic concern.
