Circuit Voltage Out of
Range
This DTC gets logged under the
following conditions~ - if the voltage
supplied by the EMS ECU voltage
supply 1 is out of range. Generally it
needs to be 5V.
EMS ECU takes following recovery
actions::~
1.
Disables cruise control function.
2.
Activates delayed engine stop
request.
3.
Disables RVD on injector cylinder1
4.
Disables RVD on injector cylinder2
5.
Disables RVD on injector cylinder3
6.
Disables RVD on injector cylinder4
7.
Disables all DTI iso diag test.
8.
Freezes (will not activates) IMV
current trim fault.
9.
Increases idle target speed.
10.
Disables cylinder balance
correction, diagnostics and tooth
learning strategy.
11.
Disable DTI iso leak test, DTI iso
IMV test & DTI HPV iso test.
12.
IMV gets fully opened.
13.
Disables PWC strategy (Pilot main
waves compensation).
14.
Disables rail Pressure sensor
learning.
15.
Disable pressure sensor learning,
uses recovery values for rail
pressure feedback and freezes
over pressure faults.
16.
Apply reduce torque 2 mode:(70%
of torque cut off at 2700erpm) or
reduce torque mode:(80% of
torque).
17.
Disables diagnostic of F M Rail
pressure control build fault.
18.
Disables the rail pressure control
fault detection.
19.
Disables SPC (Speed pilot control)
strategy, no more SPC trim
update.
1.
This fault will lead to the faults of rail pressure sensor and pedal
position sensor 1. As both the sensors are supplied by EMS
ECU voltage supply 1.
2.
Check the continuity between the EMS ECU pin A38 (rail
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 A38 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 B24 (pedal
position sensor 1 supply pin) to the pedal sensor connector
pin. Rectify if any issues found in wiring harness connections.
Check whether the EMS ECU pin B24 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.
If the problem still persists then replace EMS ECU.
