NOTE: This check is to be conducted if either the output Diagnostic Test Mode (DTM) or electrical testing indicates a malfunction in the wiring between the transmission and the Transmission Control Module (TCM) -J217-.

Test Requirements:
- Ignition switched off
- Test box VAG 1598/20 connected to 88-pin transmission wiring harness connector
- Test box VAG 1598/20 outside of and underneath vehicle

Checking Wiring Connection To 16-pin Connector On Transmission:




- Remove noise insulation.




- Unlock bayonet lock -4- of 16-pin connector to transmission by turning it (remove bracket -1- for noise insulation if necessary).




- Check wiring connections for continuity (using multimeter) between terminals of 16-pin connector and sockets of test box VAG 1598.
Refer to "16-pin Connector Specifications Table".
