This fault gets logged if the Injector-
Cylinder 4 HSD and LSD pins of EMS
ECU are short circuited across
EMS ECU takes following
recovery actions:
1.
EMS ECU doesn't activate AC
compressor relay eventhough AC
request is activated by customer
and applies default ac torque.
2.
Disables the BRC reading and use
estimation for injector pulse
duration instead of reading for
injector cylinder4.
3.
Disables cruise control function.
4.
Disables RVD(Rail Valve
Discharge) on injector cylinder4.
5.
Disables all DTI iso diagnostics
test~6. Disables EGR control and
close EGR valve.
6.
Freezes(Do not activate) IMV
current trim fault.
7.
Increases idle target speed
8.
Disables DTI iso leak test, DTI iso
IMV test & DTI HPV iso test~10.
Applies reduce torque 1
mode:(60% of torque)~11.
Disables diagnostic of Rail
Pressure build fault~12. Disables
SPC(Speed Pilot Control)
strategy, no more SPC trim
update~13. -~14. Disable Xs
ramp torque function (Torque
increase during start up if start
fails).
1.
Check Injector Connection; Switch ignition off and wait for ten
seconds. Remove injector connector; clean and reconnect
properly.
2.
Check Injector electrical continuity between ECU pins A03 &
A25 and Injector - Cylinder 4 connector pins 1 & 2 as per
circuit schematic; if required correct or replace the harness.
Check whether Cylinder 4 injector's HSD and LSD pins A03 &
A25 are short circuited due to wrong wiring harness
connections. If so then rectify the wiring harness connections
according to circuit schematics.
3.
Disconnect injector & check if fault disappear. If disappear,
injector is faulty, replace injector.
4.
Remove injector, Check continuity and resistance using a multi
meter across injector pins. (Resistance shall be ~ 0.322
ohms). If resistance is not in specified range then replace
injector.
5.
Check ECU pins for physical damage; replace ECU, if problem
still persists.
6.
After rectification ensure the following before handing over to
customer.
a) Please fit the injector with its connector on wiring harness
and remove ECU connector and check for continuity between
injector and the ECU connector.
b) Perform actuator test for the injectors.
