Configuration
This DTC gets logged due Injector C3I
values are not learned for injector
cylinder 1 to EMS ECU.
EMS ECU takes following recovery
actions:~
1.
Engine Will not Fire.
2.
Disables the BRC reading and use
estimation for injector pulse
duration instead of reading for inj
Cylinder 1
3.
Disable the BRC reading and use
estimation for injector pulse
duration instead of reading for
injector cylinder 2.
4.
Disable the BRC reading and use
estimation for injector pulse
duration instead of reading for
injector cylinder 3.
5.
Disable the BRC reading and use
estimation for injector pulse
duration instead of reading for
injector cylinder 4.
6.
Disable Pilot & Post injection.
7.
Disable RVD (Rail Valve
Discharge) on injector Cylinder 1.
8.
Freeze IMV current trim fault
(f_m_im_ctrl_qlo &
f_m_im_ctrl_qhi).
9.
Increase idle target.
10.
Disables cylinder balance
correction, diagnostics and tooth
learning strategy.
11.
Apply specific idle target for limp
home.
12.
Disables PWC strategy (Pilot main
waves compensation).
13.
Disable SPC (Speed Pilot Control)
strategy, no more SPC (Speed
Pilot Control) trim update.
1.
Rewrite the C3I values of the Injector cylinder 1 to EMS ECU by
respecting power down and up delay.
2.
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.
3.
Check whether the main relay control pin 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.
If the problem still persists then replace EMS ECU.
