Circuit open
ECU detects ECM/PCM power relay
control circuit open fault if following
condition takes place -~1: If a reset
occurs but is not due to ESM strategy or
shutdown strategy, the dropout cu relay
fault is raised.
EMS ECU disables rail pressure
calibration High fault.
1.
Check whether the 30 A fuse of main relay is blown off, if so
then replace it. Check the Main relay contacts; If any contact
weld is found then Replace Main relay.
2.
Check electrical continuity between ECU to main power hold
relay connector as per circuit schematics; Follow electrical
continuity check procedure. Replace/rectify harness if
required. Check ECU pins and connector pins for damage/rust.
In case of rust then clean them and refit the connector.
3.
Check whether the main relay control pin B45 of EMS ECU is
Open circuit/short circuit to Vbatt. In case any short
circuits/open circuits are found then rectify wiring harness
connections.
4.
Check & replace the ECU if the problem persists.

Actuator stuck closed
ECU detects ECM/PCM power relay
control circuit open fault if following
condition takes place
1.
If the relay is detected as stucked too
many times the stuck cu relay fault is
raised.
2.
If the ECU is not external power
supplied and have been shut off by
the Monitoring Module or the Main
relay but ECU is getting supply, then
there may be a stucked relay and
fault will be raised.
1.
Check 30A fuse connected to EMS power relay and battery
(+ve) power supply is not blown off. Replace if required.
2.
Check the Main relay contacts; if any contact weld is found then
Replace Main relay.
3.
Check electrical continuity between ECU to main power hold
rely connector as per circuit schematics; Follow electrical
continuity check procedure. Replace/rectify harness if
required. Check ECU pins and connector pins for damage/rust.
In case of rust then clean them and refit the connector.
4.
Check whether the main relay control pin B45 of EMS ECU is
short circuited to ground. In case any short circuits are found
then rectify wiring harness connections to make wiring harness
connections inline with circuit schematics.
5.
Check & replace the ECU if the problem persists.

No Subtype information
This fault is a grouping fault for
reference voltage 1 faults: P06A8-1C,
P0698-98.
Follow the rectification procedure of P06A8-1C/P0698-98 with
which this fault appeared for resolution

Component or System
Over Temperature
This DTC gets logged under the
following conditions~~ - if the EMS ECU
voltage supply 3 is thermally shutdown
due to over temperature.
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.
3.
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.
4.
If the problem still persists then replace EMS ECU.
