Transaxle Drive Cycle Test: Notes

CAUTION: Prior to carrying out the transaxle drive cycle test, make sure that the transaxle is full of fluid.
NOTE: Always drive the vehicle in a safe manner according to driving conditions and obey all traffic laws.

After carrying out the Quick 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 multiple times consecutively for shift error or torque converter clutch (TCC) code to set.
  • When carrying out the Transaxle Drive Cycle Test, see the solenoid operation table for correct solenoid operation. Refer to PINPOINT TESTS - NON OSC EQUIPPED VEHICLE .
  1. Record and then erase Quick Test codes.
  2. Warm engine to normal operating temperature.
  3. Make sure transmission fluid level is correct.
  4. 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 steady for minimum of 15 seconds. Brake to a stop and remain stopped for minimum of 20 seconds.
  5. Repeat Step  4 at least  5 times.
  6. Carry out Quick Test and record continuous codes.
    • If DTCs are present, refer to DIAGNOSTIC TROUBLE CODE (DTC) TABLES . Service all non-transaxle DTCs first as they can directly affect the operation of the transaxle. Repeat the Quick Test and Road Test to verify the correction. Erase DTCs, carry out the drive cycle test, and repeat the Quick 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  and check OASIS and TSBs for diagnostic concern.
