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.
