1 Check Component B6/1 (Camshaft Hall sensor) Using Actual Value.

Test requirement
- Carry out measurement with engine running.

Status of relevant actual value:
- B6/1 (Camshaft Hall sensor): Note! Communication with ECM required.

Specified value
- B6/1 (Camshaft Hall sensor): Signal IN ORDER

Question
- Is the actual value o.k.?
Yes
The actual value is okay. ** End of Test **
No
The actual value is not o.k.
Possible cause and remedy
- Test voltage supply of component B6/1 (Camshaft Hall sensor).
- Leads to component B6/1 (Camshaft Hall sensor)
- Component B6/1 (Camshaft Hall sensor)

** End of Test **


2 Test Voltage Supply of Component B6/1 (Camshaft Hall Sensor).

Test requirement
- The actual value is not o.k.

Test sequence
- Switch off ignition.
- Detach the socket at the component B6/1 (Camshaft Hall sensor).
- (B6/1) 1 <--> 3 (B6/1)
- Switch on ignition.

Specified value
- Voltage[11.0...14.5] V

Question
- Is the measured value okay?
Yes
The measured value is o.k.
Possible cause and remedy
- Signal wire
- B6/1 (Camshaft Hall sensor)
No
The measured value is not o.k.
Possible cause and remedy
- N10/1f43 (Fuse 43)
- N10/1kI (Circuit 87 relay, engine)
- Leads to component B6/1 (Camshaft Hall sensor)

** End of Test **


3 Test Signal Voltage of Component B6/1 (Camshaft Hall Sensor).

Test 3-1 The Engine Does Not Start.
Test 3-2 Engine Running.


3-1 The Engine Does Not Start.

Test requirement
- Voltage supply is o.k.

Test sequence
- Switch off ignition.
- ConnectionMeasuring system
- A4Blue socket <--> Green socketA7
- Start engine.

Specified value
- Measuring system

Note
- Measuring system:Continue with key F2

Note
- Measuring system HMS990 integrated in STAR DIAGNOSIS, is required for performing the next test step.Switch on measuring system HMS990 for this step.Continue with key F3
- If measuring system HMS990 is not integrated in your STAR DIAGNOSIS, it is also possible to carry out the next tests with alternative measuring equipment such as oscilloscope, pressure gage or digital multimeter.Continue with key F4

Question
- Is measuring system HMS990 to be started?

Question
- Is the measured value okay?
Yes
The measured value is o.k.
Possible cause and remedy
- Signal wire
- B6/1 (Camshaft Hall sensor)
No
The measured value is not o.k.
Possible cause and remedy
- N10/1f43 (Fuse 43)
- N10/1kI (Circuit 87 relay, engine)
- Leads to component B6/1 (Camshaft Hall sensor)

** End of Test **
