Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Confirmation of component activation (MODE 2): General
This function provides confirmation that certain of the system components are operating. The test consists of activating one component after the other. The control module gives a confirmation in the form of a code if it positively identifies the component as activated. In this way both the component operational status and circuit integrity checks (open-circuits and short-circuits) can be carried out at the same time.
The following components are tested:
- ON/OFF switch
- brake pedal valve
- clutch pedal valve
- RESUME switch
- SET+ switch
- SET- switch
- brake light switch
- Park/neutral position (PNP) switch (automatic transmission).
