Performance or Incorrect
Operation
1. This DTC gets logged due to the
mechanical failure of the injector of
cylinder 3 or Cylinder 3 or MDP
(minimum drive pulse) related issue of
Injector of cylinder 3
1.
EMS ECU doesn't activate AC
compressor relay even though
AC request is activated by
customer and applies default ac
torque.
2.
EMS ECU Freeze (Do not
activate) IMV current trim fault.
3.
EMS ECU Increases idle target
speed.
4.
Apply reduce torque 1 mode:(60%
of torque) or reduce torque
mode:(80% of torque).
5.
EMS ECU disable's SPC (Speed
Pilot Control) strategy, no more
SPC trim update.
6.
EMS ECU disables cruise control
function.
7.
EMS ECU diables RVD on injector
Cylinder 3
8.
EMS ECU Enters into SPC(Speed
Pilot Control) extended mode
(wider area…).
9.
EMS ECU disables IMV resistance
estimation.
1.
Check the 3rd cylinder for leaks; if noticed Perform necessary
action/repair work to arrest the cylinder leaks.
2.
Ensure Cylinder 3 Injector connector connected to the Injcector.
3.
Check the inlet ducts for blockages if any; clean the duct and
check for EGR operation.
4.
Check tappet condition & valve setting; perform the necessary
repairs in case of any problem.
5.
Check whether the injector is functioning properly or not by
performing Injector I/O control test;
6.
Check for Injector Related faults - P0203 or P2150 or P2151. If
present then follow the rectification procedure of the
respective DTC's for resolving this issue.
7.
Check whether the C3I values written into EMS ECU for injector
cylinder 3 are correct and corresponding to Injector of cylinder
3.
8.
Check for any glow plug related faults - P0380-12, P0380-11,
P0380-13, P0380-14. If present then follow the rectification
procedure of the respective DTC's for resolving this issue.
9.
Perform Compression test, if test reports a weakness of one of
engine cylinders then make necessary repairs for that
cylinder.
10.
Swap the Injector of cylinder 3 & 2, Swap thier C3I values also
and perform driving cycle. Check if P0269 disappears and
P0266 appears because of swapping, then it is confirmed that
there is a problem with Injector Cylinder 3; Replace Injector of
cylinder 3 & Rewrite the C3I values.
11.
If problem persists, replace the ECU.
12.
Final check after rectification~
Run the engine at idle for some time and check this DTC is
not re-appearing

Performance or Incorrect
Operation
This DTC gets logged under the
following conditions~ - fault of the rail
pressure control by the IMV at high fuel
delivery for high (positive) current trim
or~- fault of the rail pressure control by
the IMV at high fuel delivery for low
(negative) current trim or~- fault of the
rail pressure control by the IMV at low
EMS ECU takes following recovery
actions:~
1.
Disables cruise control function.
2.
Freezes (will not activate) IMV
current trim fault.
3.
Disable cylinder balance
correction, diagnostics and tooth
1.
Check 30A fuse connected to EMS power relay and battery
(+ve) power supply is not blown off . Replace if required.
2.
Check electrical continuity between ECU pin no A38, A35 A19
to Rail pressure sensor connector no 3 ,1, 2. Check whether
the rail pressure sensor signal pin 135 is either shorted to
battery/ground. If so then rectify the wiring harness
connections to make them inline with circuit schematics.
