Vehicle Systems, Model Year '94:

 

As of Model Year 94, various electronic vehicle systems will no longer support blink code output of trouble codes via the instrument panel telltale.

 

As Model Year 94 vehicles may already be on the market by the time the next TECH 1 Program Module 94 is available, the following solution has been developed:

Using Program Module 87-93, it is possible to read out trouble code numbers from Model Year 94 systems. For this, select Model Year 94 from the TECH 1 display

 

          OPEL/VAUXHALL

          87-93 ECU

          SELECT

          MODEL YEAR:19

 

and then select the relevant system using the arrow keys.

 

If trouble codes are stored in the system, their numbers will now be displayed. However, the description of the trouble code number (information sensor, cause of fault) will not be displayed.
