Fig 1: Identifying Communication Signals Between Electronic Throttle & Brake Pedal Systems

Courtesy of VOLVO CARS OF NORTH AMERICA.

All communication between the cruise control buttons in the steering wheel (steering wheel module (SWM)) and the engine control module (ECM) occurs via the central electronic module (CEM) and the CAN network. If the engine control module (ECM) registers that the signals from the steering wheel buttons indicate that they are all pressed simultaneously (which is impossible due to button design) for 0.3 seconds, diagnostic trouble code ECM-9200 Faulty signal is generated.

For upgraded software (released 2006 or later), the above detection time is increased from 0.3 to 1.8 seconds.

Substitute Value

Cruise control off.

Cruise control off during entire operating cycle in which fault was detected. If the fault is no longer present, the function is available the next time the car is started.

Possible Source

defective steering wheel module.

This diagnostic trouble code is generated in combination with other trouble codes. Information on the possible root cause is described.
