Description

The flexible output FLEXO-HI-0 of the gear range selector cannot be activated.

Effects on the driving operation

The flexible output FLEXO-HI-0 is non-functional.

Possible causes

An external voltage prevents activation of the transistor.

Gear range selector defective.

Place of action

Gear range selector

Instruction

Check with a multimeter whether external voltage acts on the output. For that, unplug the connector and measure to ground at the connector pin of the output. There must not be any voltage applied.

Check whether the output is overloaded. If necessary, measure the current with a multimeter by measuring the current between +IGN line and output at the unplugged connector. A maximum current of 0.5A is permitted. Attention: Before that, please check which function is controlled by the output so that this does not result in dangerous driving states. Only carry out this test with the vehicle being in parking position (best with the engine switched off)!

Replace the gear range selector.

Final function check

If the defective component cannot be clearly identified, you should try to reproduce the fault:

  • Reinstall the component in the vehicle.
  • Test function.

After the fault has been eliminated, the following steps have to be carried out:

  • Conduct a test drive with function check.
  • Read the fault memory
  • Check transmission for leaks.
  • Perform a final visual inspection.

These steps are necessary to ensure the entire vehicle functions correctly.
