Checking component and wiring
Faulty signal/Permanent or intermittent fault.
For markets where the upgraded software, released during 2006 or later, is available, the solution may be to load the upgraded software. It is no longer necessary to store a diagnostic trouble code for this type of fault. Thus, this fault type has been disabled in the upgraded software.
For other markets, check the brake pedal position sensor's attachment, cables and connectors for contact resistance and oxidation. Check that the brake pedal position sensor has the right resistance.
HINT: Using VIDA vehicle communication, check that the parameters "Brake pedal position, volts" and "Brake light switch" indicate correct values. To aid fault tracing, use Component specifications when measuring and checking relevant components and use Wiring diagram, Signal description and Breakout box to measure and control signals to and front the control module or its components.
Remedy as necessary.

Caution! In order for Electronic throttle module (ETM) to reset any reconfigurations as well as delete internally stored problems, the following must be performed:
- Ignition off, wait three minutes so that the main relay / system relay releases the voltage feed to, among other, Electronic throttle module (ETM).
- Then turn on the ignition and turn it off again.
- Wait another three minutes, but if the electric cooling fan is running you have to wait another two minutes after the cooling fan has stopped, to ensure that Electronic throttle module (ETM) is shut off correctly.
If this is not done correctly, diagnostic trouble codes may remain even after deleting diagnostic trouble codes and any reconfiguration may remain, despite the problem being fixed.
