Active Steering Module Communication
A communication fault between the chassis control module and the active steering module has been detected. Active steering varies the steering ratio with speed, and a fault disables this assistance and may store secondary codes in other modules.
Affected components
- Active steering module
- Communication bus
- Chassis control module
Common causes
- High likelihood: Communication bus fault
- Medium likelihood: Active steering module failed
- Low likelihood: Power supply or ground fault to module
Possible symptoms
- ABS warning light on
- ESC/stability control deactivated
- Possible reduced brake assist
- Speedometer may behave erratically
