Circuit resistance Below
threshold
1. This DTC gets logged, if wiring
harness resistance of Injector in cylinder
2 is below the lower threshold.
EMS ECU takes following
recovery actions:
1.
Disables the BRC reading and use
estimation for injector pulse
duration instead of reading for
injector cylinder 2.
2.
Disables RVD (Rail Valve
Discharge) on injector cylinder2.
3.
Disables PWC strategy (Pilot main
waves compensation).
4.
Applies reduce torque mode:(80%
of torque).
5.
Disables SPC (Speed Pilot
Control) strategy, no more SPC
(Speed Pilot Control) trim update.
1.
Check injector connector; Key off ignition and wait for 20
seconds. Disconnect the injector clean and reconnect
properly. Check if problem vanishes.
2.
Perform Injector cylinder 2 actuator test with the help of I/O
control command of injector cylinder 2. If this test fails then it
is confirmed that there is some issue with either injector wiring
harness/Injector itself.
3.
Check the wiring harness resistance between the Injector
cylinder 2 connector pin 2 and EMS ECU pin A74, the
resistance value should be less than 0.15 ohm. Check the
wiring harness resistance between the Injector cylinder 2
connector pin 1 and EMS ECU pin A50, the resistance value
should be less than 0.15 ohm. If the resistance found is out of
range then replace wiring harness of injector. Check the
resistance between two injector terminals it should be less
than 0.322 ohms.
4.
Check for fault codes - P0202 or P0266 or P2147 or P2148. If
any of these faults appear then resolve these faults by
following their rectification procedure.
5.
Replace injector cylinder 2 wiring harness if problem still
persists.
6.
Replace injector if problem still persists.
7.
Replace ECU if problem still persists.
