If no DTCs are recognized:







- Connect VAG1598/19 test box to ECM harness connector. Refer to "Scan Tool Testing/Scan Tool Connecting and Initial Checks/VAG1598/19 Test Box, Connecting" under "Powertrain Management" Testing and Inspection
- Check wiring for open or short circuit between ECM/test box socket C24 and ABS control module.

If wiring and ABS control module are OK:
- Replace ECM.
- Generate readiness code. Refer "Monitors, Trips and/or Drive Cycle (Readiness Code)/Generating, Readiness Code" under "Powertrain Management" Testing and Inspection
