After on-Board Diagnostics

After On-Board Diagnostics

NOTE: The vehicle wiring harness, powertrain control module 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 procedures(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 (PCM) 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.

Before Pinpoint Tests

NOTE: Prior to entering pinpoint tests, check the powertrain control module (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.

NOTE: If a concern still exists after electrical diagnosis has been carried out, refer to Diagnosis By Symptom.

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 and for transaxle concerns.
