Check whether IMV is stuck closed, if so replace the IMV.
20.
After rectification ensure the following before handing over to
customer. ~ a) Rail pressure at ignition key on is < 10 bar,~ b)
By removing the rail pressure sensor connector shows a very
rail pressure value in bar, ~ c) High pressure leak detection test
can be carried out. ~ d) Please drive the vehicle on road, check
and ensure rail pressure feed-back follows the demand
continuously.(feedback and demand parameters can be
monitored by using diagnostic tool)

Circuit Open.
This fault gets logged if the VGT
actuator drive pin of EMS ECU is open
circuited.
ECU used to take following
recovery action if it found
turbocharger/supercharger boost
control "A" circuit issue:-
1.
Disable the AMF sensor learning.
2.
Disable the AMF plausibility test.
3.
Disable cruise control function.
4.
Disable EGR control and close
EGR valve~5. Apply reduce
torque 3 mode :( 70% of torque
cut off at 2700erpm).
5.
Disable SPC (Speed Pilot Control)
strategy, no more sPC trim
update.
6.
VGT position control disabled and
recovery position applied.
1.
Check 30A fuse connected to EMS power relay and battery
(+ve) power supply is not blown off. Replace if required.
2.
Check whether VGT actuator is stuck open/mechanical damage
to VGT actuator. In case of severe damage replace VGT
actuator.
3.
Check the continuity between the EMS ECU pin A89 to the
VGT actuator connector pin 4 && Main relay power supply to
Actuator connector pin 1 and rectify if any wiring harness issues
are found.
4.
Check whether the VGT actuator connector pin 2 is connected
to ground and Connector pins 3 & 5 are connected to CAN H
and CAN L lines.
5.
Check ECU pins and connector, Replace if found defective.
6.
If still problem persists then replace VGT actuator with new
one.
7.
If problem still persists then replace EMS ECU.
8.
Check 30A fuse connected to EMS power relay is functioning
properly. Replace if found faulty.
