Signal high time >

This fault gets logged if the Duty cycle of
the IMV PWM input is greater than a
maximum calibrated duty cycle
threshold of IMV PWM input.
EMS ECU takes following recovery
actions:
1
. Freezes(will not activate) IMV
current trim fault.
2
. Disable cylinder balance
correction, diagnostics and tooth
learning strategy.
3
. Disables the rail pressure control
fault detection.
4
. Disables SPC strategy, no more
Spc trim update.
1.
Check 30A fuse connected to EMS power relay and battery
(+ve) power supply is not blown off. Replace if required.
2.
Ensure IMV connector is properly connected to the IMV.
3.
There is no mud, dirt, foregn particle accumulation on the
connector.
4.
Check electrical continuity of wiring harness between ECU pin
A77 and IMV connector pin 2 & EMS ECU main relay supply
and IMV connector pin 1 as per circuit schematics. Correct if
necessary.
5.
Check whether the IMV control pin of EMS A77 is short
circuited to ground/Battery because of wrong wiring harness
connections. If so rectify the wrong connections to make the
connections inline with circuit schematics.
6.
Check wiring harness resistance between IMV and ECU and
check whether it is according to the design specifications (xx
to xx ohms).
7.
Check for IMV actuator stuck issues, Replace IMV if any
mechanical stuck issues are found.
8.
Check IMV internal resistance whether it is according to the
design specifications (5.3 ohms at 20 deg C). Replace IMV if
the resistance is not according to specifications.
9.
Perform IMV buzzing test using I/O Control Command, if IMV is
not buzzing then replace IMV.
10.
Replace ECU if problem persists~11. After rectification
perform actuator test for IMV and ensure the result is
positive.~

Signal Below Allowable
Range.
This fault gets logged If the difference
between the rail pressure demand and
the rail pressure feedback is less than a
calibrated minimum threshold for rail
pressure in IMV mode.
EMS ECU takes following recovery
actions:
1.
Disables SPC strategy, no more
sPC trim update.
2.
Applies reduce torque 1 mode :(
60% of torque).
3.
Disables cylinder balance
correction, diagnostics and tooth
learning strategy.
4.
Disables cruise control function.
1.
Check 30A fuse connected to EMS power relay and battery
(+ve) power supply is not blown off . Replace if required.
2.
Check electrical continuity between ECU pin no A38, A35 A19
to Rail pressure sensor connector no 3 ,1, 2. Check whether
the rail pressure sensor signal pin A35 is either shorted to
battery/ground. If so then rectify the wiring harness connections
to make them inline with circuit schematics.
3.
Check electrical continuity of wiring harness between ECU pin
A77 and IMV connector pin 2 & EMS main relay supply and
IMV connector pin 1. Rectify wiring harness connections in
case of any issue. Check 30A fuse connected to EMS power
