What This Code Means
Glow plug power stage electric failure; Electric Throttle Valve actuator power stage electric failure; Short circuit to Battery (SCB); Short circuit to Ground (SCG); Overload failure; Deviation between required and measured Throttle Valve position; Jammed Valve; Electric failure of glow plug power stage; Electric failure of electric Throttle Valve actuator (H-Bridge) power stage
Possible Causes
- •Faulty relay between ECU and Glow plug
- •Electric failure of glow plug
- •Electric failure in H-Bridge circuit switches (High side or Low side)
- •Short circuit to Battery (SCB)
- •Short circuit to Ground (SCG)
- •Overload
- •Blocked actuator
- •Faulty relay between ECU and glow plug
- •Electric failure in high side circuit of H-Bridge
- •Electric failure in low side circuit of H-Bridge
- •Throttle Valve position sensor deviation
Suggested Actions
- 1System performs automatic plausibility check by closing the Low side switch (for SCB) or High side switch (for SCG) to clear the short circuit and activate overload failure
- 2System attempts to 'unblock' the actuator by closing or opening it fast
- 3System performs plausibility check by closing the low side switch (for SCB) or high side switch (for SCG) to verify if the failure clears
- 4System attempts to unblock the actuator by closing or opening it rapidly
