6 Speed - Automatic Transaxle/Transmission
Transaxle Drive Cycle TestCAUTION: Prior to carrying out the transaxle drive cycle test, make sure that the transaxle is full of transmission fluid or damage to the transaxle may occur.
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 multiple times consecutively for shift error or 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 - Non OSC Equipped Vehicle. Pinpoint Tests - Non OSC Equipped Vehicle
1. Record and then erase Self Test codes.
2. Warm engine to normal operating temperature.
3. Make sure transmission fluid level is correct.
4. With the selector lever 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 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 the drive cycle test, and repeat the Self Test after completing service on the DTCs. 6 Speed - Automatic Transmission
^ If the continuous test passes (system pass) and a concern is still present, refer to Diagnosis By Symptom and check TSBs for diagnostic concern. 6 Speed - Automatic Transmission
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. Refer to the Diagnostic Trouble Code (DTC) Charts 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 powertrain control module are diagnosed as well. Refer to Computers and Control Systems for diagnosing non-transaxle electronic components. The diagnostic routine hydraulic/mechanical charts will help in diagnosing internal transaxle concerns and external non-transaxle inputs. 6 Speed - Automatic Transmission
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. Refer to Computers and Control Systems.
NOTE: If a concern still exists after electrical diagnosis has been carried out, refer to Diagnosis By Symptom. 6 Speed - Automatic Transmission
If DTCs appear while carrying out the on-board diagnostics, refer to the Diagnostic Trouble Code (DTC) Charts for the appropriate repair procedure. Prior to entering pinpoint tests, refer to any TSBs for transaxle concerns. 6 Speed - Automatic Transmission
