Indication and Cancellation of memorised sensor and circuit faults
Selection and clearing of stored service codes:
Procedure:
* Ignition – OFF
* Connect Tool VR00135/1 to Diagnostic Outlet Plug (X23)
* Ignition – ON
NOTE: The program changes automatically to indication of service codes.
If no service code is stored, only repeating control code reading “Code # 12” will be displayed.
Possible memorized codes are indicated as shown in the previous illustrated example (blinking 3x
Code # 12 i. e. 3x service code # 14 etc.) The sequence will be prolonged with additional codes if
more then one service code is stored. See Table – Service codes for description
* To delete a determined service code from the Engine Management System concentrate for the 3
rd
times flashing
the desired service code. While this service code is displayed the third time the button (Tool VR00135/1) must be
pushed and kept in this position (contact open).
* The indication on the Check Engine Light changes to a fast blinking of the lamp (app. 4 times per sec.). During this
rapid flashing light the push button must be released (close contact after app. 2 sec.) to delete this service code.
NOTE: Any other service code have to be selected and cleared individually following the above men-
tioned procedure to delete a determined service code.
NOTE: An service code can only be deleted if no defect exists in this circuit. In case of a present active
failure, the service code keeps reappearing until the problem has been repaired and the circuit is
properly working again.
* Disconnect Tool VR00135/1 from Diagnostic Outlet Plug (X23) to exit from service code display.
NOTE: Watch indication of the Check Engine Light and the Warning Horn after ignition contact. If all ser-
vice codes are deleted from the Engine Management System the indication resumes to 0.7 sec.
function test of Check Engine Light and the Warning Horn. For additional details see Chart – Op-
erating Conditions – Instrument panel.
