On-board diagnosis
Type of diagnosis:
Enable criteria:
| No fault on main relay (P0685, P0686 and P0687). |
Fault criteria:
| When there is no trigger signal, ignition coil cyl 2 to CDM (pin 10) for 16 combustions. |
Dependent:
System reaction to a fault:
| Torque limited to max. 170Nm. |
OK report:
| When trigger signal, ignition coil is detected 4 times in a row per cylinder (total 16 combustions). |
Fault handling:
| (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.
