Harness Connectors between TCM and Transmission, Checking

Harness Connectors between TCM and Transmission, Checking

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) => [ Transmission Control Module ] 01V,01VA Transmission and separate multiple connector => 01V,01VA Transmission.

- Connect test box (VAG1598/20) 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 (VAG1598/20 ), as described in following chart.





• Specified value always less than 1.5 ohms





• 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 OK. should the appropriate solenoids or pressure control valves be replaced.
