ignition AUDI A4 2001 B5 / 1.G 01V Transmission Electrical Testing Workshop Manual

01-276


- For all test steps, switch ignition off, disconnect multi-pin connector for
Transmission Control Module (TCM) -J217- (located in front of
passenger seat under carpet in foot well page 01
-11
) and connect
VAG1598/20 adapter to wiring harness connector.
- If measuring values do not match specifications, follow instructions in
right-hand column of test table (labelled "Corrective action") page
01
-11
.
- Always perform all steps indicated in the "Corrective action" column.
- Only perform test steps recommended in the DTC table (selective
troubleshooting).
