Harness Connectors Between the Transmission Control Module (TCM) and Transmission, Checking

Harness connectors between the Transmission Control Module (TCM) and transmission, checking, 01V, 5 Spd. A/T AWD
Perform this test if the control element diagnosis or the electrical test points to problems between the transmission and Transmission Control Module (TCM) -J217-.

Test procedure
- Remove Transmission Control Module (TCM) and separate multiple connector.





- Connect V.A.G 1598/20 test box to control module wiring harness.





- Remove sound deadening -arrows-.

Checking harness connectors to the 16-pin connector at the transmission





- Unscrew retainer -1- for sound deadening.
- Rotate locking lever -3- and remove connector for transmission wiring harness.





- Connect Multimeter to make a resistance measurement between terminals of 16-pin connector and cavities of test box V.A.G 1598/20, as described in following chart.
^ Specified value always less than 1.5 Ohms.





Note:
^ In the event of deviations from the specified value, repair open circuit following wiring diagram and check connector for corroded terminals, water entry and leakage.
^ If this test revealed no unacceptable deviations, the wiring harness in the transmission must be tested.
^ Only if the wiring harness in the transmission is O.K. should the appropriate solenoids or pressure control valves be replaced.
