Test procedure

1 First check to see whether any fault codes have been generated. If so, attend to these first.

2 Check the OG lead between pin 12 of the ETS control unit and pin 29 of the DI/APC control unit for continuity or shorting to earth.Also check the WH and BU/RD leads between pin 27 of the ETS control unit and pin 25 of the LH control unit for continuity or shorting to earth.

3 Check that the control unit's earth connection at the engine earthing point is OK.

4 If the above tests check out OK, clear the fault code and drive the car to see whether it is generated afresh.
If it is, try fitting an ETS control unit which is known to be good.
