Peugeot/Citroen Disconnection Speed Limitation
Supported coding features by PSACOM diagnostic tool https://www.obdtester.com/psacom
Disconnection Speed Limitation
What it does
- Activates a speed limitation when critical systems are disconnected
- Protects drivetrain, brakes, and electronic systems
- Prevents unsafe driving conditions during service or fault states
When it is required
- When driving with disconnected sensors or control units
- During diagnostic or service procedures
- After detecting critical system disconnections
- As a safety fallback imposed by the ECU
Conditions that must be met
- Vehicle in service or fault condition
- One or more critical systems disconnected
- Ignition ON
- Stable battery voltage
What happens during speed limitation
- ECU limits maximum vehicle speed
- Engine power or throttle response is reduced
- Warning messages may appear in the instrument cluster
- Vehicle remains drivable at reduced speed only
If limitation is not managed correctly
- Vehicle may be unsafe to drive
- Risk of component damage
- Legal or safety compliance issues
- Persistent warning messages
After procedure / reconnection
- Reconnect all required components
- Clear related fault codes
- Deactivate speed limitation automatically or via diagnostics
- Verify full vehicle performance is restored
