STATUS
CEL
fuel delivery for high (positive) current
trim or~- fault of the rail pressure control
by the IMV at low fuel delivery for low
(negative) current trim~~
learning strategy.
4.
Defines min rail pressure demand
recovery value.
5.
Disable SPC(Speed Pilot Control)
strategy, no more SPC trim
update.
3.
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. rectify wiring harness connections in
case of any issue.
4.
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.
5.
Check IMV internal resistance whether it is according to the
design specifications(5.3 ohms at 20 degrees C). Replace
IMV if the resistance is not according to specifications.
6.
Check whether adequate fuel level is available in the tank.
7.
Check high pressure fuel lines for leakage.
8.
Check fuel filter is not clogged.
9.
Check low pressure fuel lines for air entry.
10.
Check & ensure IMV and railpressure sensor connectors for
proper fitment.
11.
Check rail pressure sensor for oxidation, rust etc, if observed
clean deposit.
12.
Check harness for damages; Replace / Repair if harness is
damaged.
13.
Check ECU pins and connector, Replace if found defective.
14.
If vehicle is unable to start the perform 'Static injector back
leak test', Please check if any injector back leak is abnormally
high compared to other injectors, then replace corresponding
injectors.
15.
If vehicle is able to start then start the vehicle and perform
'Dynamic IMV test' - If test result shows IMV is faulty then
replace IMV.
16.
If vehicle is able to start then start the vehicle and perform
'Dynamic injector back leak test', Please check if any injector
back leak is abnormally high compared to other injectors, then
replace corresponding injectors.
17.
If vehicle is able to start then start the vehicle and perform
"Pump pressure build capacity test' - If test result shows not
ok then replace HP pump.
18.
Check whether High pressure pump is functioning
properly/able to build pressure else replace high pressure
pump.
