Idle Stabilizer: Operation
- Turn ignition switch on. Idle stabilizer should vibrate and hum. If stabilizer does not operate, disconnect connector from idle stabilizer. Using Tester (VW 1325 A-1), check for continuity. Continuity should exist.
- Replace idle stabilizer if no continuity exists. If continuity is obtained, reconnect connector to valve. Check electrical connections on control unit relay adapter located in front of right tail light.
- Replace idle stabilizer control unit if electrical connections are okay.
