P06A7
1C
Circuit Voltage Out of
Range
This DTC gets logged under the
following conditions~ - if the voltage
supplied by the EMS ECU voltage
supply 2 is out of range. Generally it
needs to be 5V.
EMS ECU takes following recovery
actions:~
1.
Disable cruise control function.
2.
Disable EGR control and close
EGR valve.
3.
Increases idle target speed.
4.
Disable dTI iso leak test, DTI iso
IMV test & DTI HPV iso test.
5.
Apply reduce torque 1 mode:(60%
of torque) or Apply reduce torque
mode:(80% of torque).
6.
Disable SPC(Speed Pilot Control)
strategy, no more SPC trim
update~7:-VGT control disabled
=> Open loop control~8:--~~
1.
This fault will lead to the faults of boost pressure sensor, cruise
control, and pedal position sensor. As all these sensors are
supplied by EMS ECU voltage supply 2.
2.
Check the continuity between the EMS ECU pin A42 (Boost
pressure sensor supply pin) to the sensor connector pin 3 and
rectify if any issues found in wiring harness connections.
Check whether the EMS ECU pin A42 is short circuited to
battery/ground due to wrong wiring harness connections, if so
then rectify the wiring harness connections to make them inline
with circuit schematics.
3.
Check the continuity between the EMS ECU pin A43 (cruise
control supply pin) to the connector pin and rectify if any issues
found in wiring harness connections. Check whether the EMS
ECU pin A43 is short circuited to battery/ground due to wrong
wiring harness connections, if so then rectify the wiring
harness connections to make them inline with circuit
schematics.
4.
Check the continuity between the EMS ECU pin B29 (pedal
position sensor 2 supply pin) to the sensor connector pin and
rectify if any issues found in wiring harness connections.
Check whether the EMS ECU pin B29 is short circuited to
battery/ground due to wrong wiring harness connections, if so
then rectify the wiring harness connections to make them inline
with circuit schematics.
5.
If the problem still persists then replace EMS ECU.

Circuit Voltage Out of
Range
This DTC gets logged under the
following conditions~ - if the voltage
supplied by the EMS ECU voltage
supply 3 is out of range. Generally it
needs to be 5V.
ECU used to take following recovery
action if it found Sensor Reference
Voltage "C" Circuit
Range/Performance issue:-
1.
Disables cruise control function.
2.
Disables EGR control and close
EGR valve.
3.
Disables EGR valve supply =>
EGR valve probably closed.
4.
Applies reduce torque mode:(80%
of torque).
5.
Disables SPC (Speed Pilot
Control) strategy, no more SPC
trim update.
1.
This fault will lead to the faults of EGR feedback sensor. As
both the sensors are supplied by EMS ECU voltage supply 3.
2.
Check the continuity between the EMS ECU pin A65 (EGR
feedback sensor supply pin) to the sensor connector pin 3 and
rectify if any issues found in wiring harness connections.
Check whether the EMS ECU pin A65 is short circuited to
battery/ground due to wrong wiring harness connections, if so
then rectify the wiring harness connections to make them inline
with circuit schematics.
3.
If the problem still persists then replace EMS ECU.
