On-Board Diagnostics II

The Following Tools Are Needed For Troubleshooting:




System Tester 9288 or Normal Scan Tool




Porsche System Tester 2 or commercially available scan tool




Special tool 9616




Commercially available digital multimeter




V.A.G. 1501




Special tool V.A.G 1315 A/1




Special tool P 378 with connection lead 9559




Special tool VW 387




Special tool 9264/1




Special tool 9160/1




Special tool 9103/2




NOTE: For resistance measurements on the components, the special tool 9616 must be connected only to the wiring harness, as the values could otherwise be falsified via the ECM. The test adapter must be used for all tests on electrical leads (e.g. transmission control module - connector/sensors). It does not damage the plug-in contacts and facilitates location of the individual pins.
