Fault code
112204 - P310E

Fault text
Injector, cylinder 2, activation: short circuit, high-voltage
side to low-voltage side

Fault description
The diagnostic function monitors electrical activation of the
injector.

Condition for fault identification
Test condition:
The fault is recognized when the injector voltage is < 50V
and the injector charge is > 1200 �As and the conditions for
internal current monitoring are present (current integral and
charge characteristics allowing detection of the various
short-circuit types).
Potential problem source(s):
- Injector 2 defective
Terminal condition: none
Voltage condition:
- Electrical system voltage > 10 V
Temperature condition:
- Coolant temperature > -20 °C
Time condition:
- None
Other conditions:
- Engine on

Condition for fault memory entry
This fault is logged in the control module's fault memory
immediately.

Action in service
- Check injector 2: Measure the resistance between the pins
for the injectors, (specified: 200 kOhm +/-10 kOhm), if the
specified value is not obtained, replace the injector

Fault effect and breakdown warning
Breakdown notice:
- The engine reverts to its limp-home program, continued
vehicle operation is possible but drivability is restricted,
because power is reduced the driver should refrain from
passing maneuvers.
Possible apparent symptoms:
- Engine runs poorly with power loss

Driver information
Warning light:
- ECE emissions warning lamp: on
- US emissions warning lamp: on
- ECE electronic engine power reduction: on
- US electronic engine power reduction: on
- CC message: on

Service instruction
- none
