Signal high time >
maximum.
1. This fault gets logged if Incorrect
PWM signal is applied to VGT actuator
by EMS ECU.
EMS ECU takes following
recovery actions:
1.
Apply reduce torque 3 mode:(70%
of torque cut off at 2700erpm)
2.
Disable SPC strategy, no more
sPC trim update.
3.
VGT position control disabled and
recovery position applied.
4.
Disable the AMF sensor learning.
5.
Disable the AMF plausibility test.
6.
Disable cruise control function.
7.
Disable EGR control and close
EGR valve.
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 whether the VGT actuator control pin A89 is either short
circuited to ground/battery. If so the rectify the wiring harness
connections to make them inline with circuit schematics.
6.
Check ECU pins and connector, Replace if found defective.
7.
If still problem persists then replace VGT actuator with new
one.
8.
If problem still persists then replace EMS ECU.

Circuit Short to Ground
This fault gets logged if the VGT
actuator drive pin of EMS ECU is short
circuited to ground.
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.
