After On-Board Diagnostics

NOTE: The vehicle wiring harness, Powertrain Control Module (PCM) and non-transaxle sensors may affect transaxle operations. Repair these concerns first.

After the on-board diagnostic procedures are completed, repair all DTCs.
Begin with non-transaxle related DTCs, then repair any transaxle-related DTCs. The pinpoint tests are used in diagnosing electrical concerns of the CD4E transaxle. Make sure that the vehicle wiring harness and the PCM are diagnosed as well. The diagnostic routine hydraulic/mechanical charts will help in diagnosing internal transaxle concerns and external non-transaxle inputs.
