P1350 00

Ignition Coil Trig Random Cylinder, Signal Missing at CDM







Fault symptom
- Malfunction Indicator Lamp
- Performance loss.
- Misfiring

On-board diagnosis

Type of diagnosis:
- Continuous

Enable criteria:
- Engine running.
- No fuel shut-off.
- No fault on main relay (P0685, P0686 and P0687).

Fault criteria:
- When there is no trigger signal, ignition coil, several cylinders to CDM for 16 combustions.

Dependent:
P1315

System reaction to a fault:
- Torque limited to max. 170 Nm.

OK report:
- When trigger signal, ignition coil is detected 4 times in a row per cylinder (total 16 combustions).

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.
