What does this fault code mean?
The engine control module (ECM) receives messages from the CEM and the FSM about whether adaptive cruise control is permitted. The code is set when these messages say it is not permitted, and then the cruise control does not work at all. The code is set after the fault has been stored in the CEM or the FSM.
Possible causes
- The fault is in the central electronic module (CEM)
- The fault is in the forward sensing module (FSM)
What you can do
- 1Read the fault codes in the CEM and FSM and remedy them first. This code can be erased only once the root fault is remedied and its fault code erased.
- 2No troubleshooting has been developed for this code. If it returns, have a workshop troubleshoot the CEM and FSM with diagnostic equipment.
- 3If the engine control module has been reloaded or the battery has been disconnected, press the brake pedal down twice for about two seconds to activate cruise control.
Symptoms you may notice1
- Cruise control does not work at all
What the fault can affect1
- Cruise control is turned off while the fault is active
