Your vehicle should be fitted with an LED in the diagnostic harness located on the right hand side of the engine compartment. This provides some limited information regarding the engine MIL (Malfunction Indicator Lamp). Press and hold the button for 3 seconds then release, count the blinks-pause for 5 seconds after each code and repeat the process until the codes are repeated.

We can provide you with some insight once we have an idea of the codes that are stored in that particular system , I believe it is the DM (Diagnostic Module).
