circuit to ground

Fault description
The diagnostic function monitors control-activation of the
injector's low-voltage side.

Condition for fault identification
Test condition:
The fault is recognized when a short circuit to ground is
present.
Potential problem source(s):
- Defective wiring harness
- Defective injector
- Defective DME
Terminal condition: none
Voltage condition:
- Onboard electrical system voltage between 9 V and 16 V
Temperature condition:
- None
Time condition:
- None
Other conditions:
- Engine ON

Condition for fault memory entry
The diagnostic fault code is entered when the fault occurs 3
times in sequence with no interruption on a single cylinder.

Action in service
- Inspect wiring harness between DME and injector 2,
replace injector 2.
- Replace DME only if the fault remains continuously

Fault effect and breakdown warning

Engine fault
Possible apparent symptoms:
Engine runs roughly and can stall in extreme cases

Service instruction
Injectors 1 and 6, and 3 and 4, are connected to shared DME
driver circuits. This means that diagnostic fault codes are
always logged for both injectors, although usually only one
is defective. When interchanging positions use injectors
operated by a DME driver circuit that only activates one
injector!
