Fault-Tracing Information

Fault-tracing

Start of new driving cycle




Before the diagnostic trouble code' status is read out it is important to start a new driving cycle.
- Ignition on.
- Restart Steering wheel angle sensor module (SAS) by pressing on the symbol for VCT2000 and press start.

Note! This action may mean that diagnostic trouble codes are stored in other control modules that are dependent on continuous information of current steering wheel angle from Steering wheel angle sensor module (SAS) via CAN. These diagnostic trouble codes shall be deleted without action.

-------------------------------------------------

Checking the status




- Start the engine.
- First turn the steering wheel max. to the right, then max. to the left. Then set the steering wheel to the straight-ahead position.
- Read the trouble code counter by clicking the VCT2000 symbol.
The counters are used to determine the problem's status. For general information about the counters, see: Description of counter Description Of Counter Counters 5, 6 and 7 are not used during this check.
Counter 1 indicates the number of drive cycles without fault since the fault was last validated.
If counter 1 is the same as 0, this means that the fault has been detected in this operating cycle (permanent fault). Replace the Steering wheel module (SWM).
If counter 1 is over 0, this indicates that the problem has not been detected in this driving cycle (intermittent problem). The problem has existed earlier but is not active right now. The digit indicates number of driving cycles since the diagnostic trouble code was generated. Then check counter 4. Counter 4indicates number of driving cycles with problem since the problem was validated for the first time.
- If the number of incorrect driving cycles is high, this indicates an intermittent recurring problem. Replace the Steering wheel module (SWM).
- If the number of incorrect driving cycles is low, this indicates an intermittent temporary problem. No action.

Hint: Counter 3 indicates number of driving cycles since first time that the problem occurred. If the value for counter 3 is divided by the value for counter 4, the intensity of the problem is obtained. The higher the value, the higher the problem intensity. A high problem intensity indicates that the malfunction recurs often.

Note! Replace the steering wheel module (SWM) if the fault recurs.

Remedy as necessary.
