Pinpoint Tests - Non OSC Equipped Vehicles

Pinpoint Tests - Non OSC Equipped Vehicle

Special Tool(s):

NOTE: Prior to entering pinpoint tests, the vehicle harness must be checked for continuity and shorts, and the powertrain control module (PCM), engine control module (ECM), DEM module and other modules and non-transmission sensors may affect transmission operations must be checked for any concerns. Refer to Computers and Control Systems for diagnosis and testing of the PCM concerns. Repair all non-transmission component and module concerns first.

NOTE: If any non-transmission repair codes appear, repair those codes first. They could affect the electrical operation of the transmission. Record and erase codes from continuous memory after repairs have been carried out. After repairing any fault codes in the Quick Test, the Quick Test should be repeated.

Any time an electrical connector or transaxle connector is disconnected, inspect the connector for pin condition, corrosion and contamination. Also inspect the connector seal for damage. Clean, repair or install a new connector as required.

Prior to carrying out the pinpoint tests check the following:
^ Transmission fluid level
^ Transmission fluid condition (burned, metal particles or discolored)
^ Engine cooling system
^ Other non-related transaxle DTC
