Hva betyr feilkoden?
The engine control module (ECM) drives the bypass valve with a PWM signal. The fault is set when the control module registers a fault on that signal, or when the end stage for the valve becomes too hot. The end stage is built into the control module.
Mulige årsaker
- Loose contact, contact resistance or oxidation in the connections
- Signal wire shorted to ground
- Open circuit in the supply voltage
- Open circuit in the signal wire
- Damaged bypass valve
