Drive System Voltage Low
The chassis control module has detected that the supply voltage is below the operating threshold required for ABS, ESP or steering systems. Many chassis functions are limited or disabled until the voltage returns to a normal range.
Affected components
- Battery
- Alternator
- Power supply wiring
- Chassis control module
Common causes
- High likelihood: Battery weak or discharged
- Medium likelihood: Alternator output fault
- Low likelihood: High-resistance ground or supply connection
Possible symptoms
- ABS warning light on
- ESC/stability control deactivated
- Possible reduced brake assist
