Circuit Short To Ground
1. This fault will gets logged if either
HSD of injectors in cylinders 3 & 4 are
Short circuited to GND.
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 disables the BRC
reading and use estimation for
injector pulse duration instead of
reading for injector cylinder 2.
3.
EMS ECU disables the BRC
reading and use estimation for
injector pulse duration instead of
reading for injector cylinder 4.
4.
EMS ECU disables all DTI iso diag
test.
5.
EMS ECU Increases idle target, so
idle speed increases.
6.
EMS ECU disables cylinder
balancing compensation.
7.
EMS ECU applies reduce torque 1
mode:(60% of torque).
8.
EMS ECU disables SPC (Speed
Pilot Control) strategy, no more
SPC trim update.
9.
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 and Injector
connector as per circuit schematic; if required correct or
replace the harness. Check whether the EMS ECU pins A51
& A03 (HSD's of injector cylinder 3 & 4) pins are short circuited
to ground, If so then replace the wiring harness connections.
3.
Check continuity using a multi meter across injector pins.
Replace injector if found faulty.
4.
Check ECU pins and connector pins for damage.
5.
Check ECU; 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.

Circuit Short To Battery
1. This fault will gets logged if either
HSD of injectors in cylinders 3 & 4 are
Short circuited to Battery.
1.

compressor relay even though AC
request is activated by customer
and applies default ac torque.

reading and use estimation for
injector pulse duration instead of
reading for injector cylinder 2.

connector as per circuit schematic; if required correct or
replace the harness. Check whether the EMS ECU pins A51
& A03 (HSD's of injector cylinder 3 & 4) pins are short circuited
to battery, If so then replace the wiring harness connections.
3.
Check continuity using a multi meter across injector pins. ~4.
Disconnect injector & check if fault disappear. If disappear,
injector is faulty, replace it.
4.
Check ECU pins and connector pins for damage.
5.
If problem still persists then replace injector.
6.
Check ECU for any physical damage; replace ECU, if problem
still persists.
