Transaxle Drive Cycle Test

TRANSAXLE DRIVE CYCLE TEST

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 carried out exactly. Faults must occur 4 times consecutively for shift error DTC to be set, and 5 times consecutively for continuous torque converter clutch code to set.
NOTE:When carrying out the Transaxle Drive Cycle Test, refer to the Solenoid Operation Chart for correct solenoid operation. See - Pinpoint Tests - Output State Control (OSC) Equipped Vehicles.
1. Record and then erase self-test codes.

2. Warm engine to normal operating temperature.

3. Make sure transaxle 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 opening steady for a minimum of 15 seconds.

5. 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.

6. Brake to a stop and remain stopped for minimum of 20 seconds.

7. Repeat Steps 4 through 6 at least 5 times.

8. Carry out self-test and record continuous codes.

- If DTCs are present, see Automatic Transmission/Transaxle - DTC Chart. 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, see Diagnosis By Symptom. Check TSBs and Mazda TIPS for diagnostic concern.

After On-Board Diagnostics

NOTE:The vehicle wiring harness, PCM and non-transaxle sensors may affect transaxle operations. Service these concerns first.
After the On Board Diagnostic procedures are completed, service all DTCs.Begin with non-transaxle related DTCs, then service any transaxle related DTCs. See Automatic Transmission/Transaxle - DTC Chart for information on Condition and Symptoms. This chart will be helpful in referring to the correct manual(s) and to aid in diagnosing internal transaxle concerns and external non-transaxle inputs. The pinpoint tests are used in diagnosing electrical concerns of the transaxle. Make sure that the vehicle wiring harness and the PCM are diagnosed as well. See - PCM - DTC Index for diagnosing non-transaxle electronic components. The diagnostic routine hydraulic/mechanical charts will help in diagnosing internal transaxle concerns and external non-transaxle inputs.

Before Pinpoint Tests

NOTE:Prior to entering pinpoint tests, check the PCM wiring harness for correct connections, bent or broken pins, corrosion, loose wires, correct routing, correct seals and their condition. Check the PCM, sensors and actuators for damage. See Troubleshooting 2.5L and 3.0L.
NOTE:If a concern still exists after electrical diagnosis has been carried out, see Diagnosis By Symptom.
If DTCs appear while carrying out the on-board diagnostics, see Automatic Transmission/Transaxle - DTC Chart for the appropriate repair procedure. Prior to entering pinpoint tests, refer to any TSBs or Mazda Tips for transaxle concerns.
