Verification, Part 1

Verification, Part 1







HINT: After carrying out the repair, check that the fault has been remedied.

- Verification consists of 2 parts. Part 1 is carried out via a test in the workshop. Part 2 is carried out on the road.

If the function is determined as incorrect in part 1, then part 2 does not need to be carried out. If the function is determined as being correct in part 1 and the vehicle can be tested on the road, part 2 must be carried out. This is because in certain cases the function can be difficult the check in a workshop environment.

- Ignition off
- Reconnect the connectors, components, etc.
- Start and run the engine to operating temperature.
- Read off the shift angle of the camshaft and the desired shift angle of the camshaft to check the function.

Check that the camshaft shift angle corresponds to the desired value for the camshaft shift angle with an accuracy of approximately 8 degrees CA (camshaft angle). The difference between the values can be read off in the lower digital display.

Is the function OK?

YES: Refer to Verification, Part 2. Verification, Part 2
NO: Refer to Fault-Tracing Information - Permanent Fault.
