Reduced System Function |
- Event information Not a fault condition. System operation suspended
while system cools. Customer may have seen the warning lamp illuminated
during a period of reduced functionality or may have noticed the vehicle
behaving differently in relation to a traction control event.
|
This Event is triggered if the ECU reduces the level of
functionality, to prevent over heating of the foundation brakes. It is a
normal function of the ECU and is not a fault. Clear/ignore this DTC.
