Diagnosis/troubleshooting

Diagnosis/troubleshooting:

Test tool 9516/4 instead of belt tensioner










NOTE: If the fault memory is cleared, the ignition must be switched off, the ignition key removed and the ignition switched on again in order to check the fault path. Only in this way is another self-test carried out.
