Ignition Coil Trig Cylinder 1 Circuit, Short to Ground







Fault symptom
- Check Engine
- Flickering pressure indicator in MIU.
- Misfiring
- Jerky movements.
- Performance loss.

On-board diagnosis

Type of diagnosis:
- Continuous

Enable criteria:
- Engine running.

Fault criteria:
- Output voltage below 2 V when the control module is not grounding.
- The condition exists for more than 1 s.

Dependent:
- None

System reaction to a fault:
- Fuel to the injector in question is cut off.
- Closed loop is blocked.
- Fuel adaption is blocked and reset.

OK report:
- Fault criteria NOT fulfilled for 2 s.

Fault handling:
Type III
(See section Fault handling III, "Other emission-related components and functions" for more information.)

Checking the wiring harness
- Move the wiring harness at several spots and in several directions to reveal intermittent breaks and short-circuits. Check switches, connectors and crimp connections for oxidation, retracted pins and pin clamping force.
