Cylinder 2 Injection Timing
This DTC gets logged due to the
mechanical failure of the injector of
cylinder 2 or MDP (minimum drive
pulse) related issue of Injector of
cylinder 2
1.
EMS ecu doesn't activate AC
compressor relay even though AC
request is activated by customer
and applies default ac torque.
2.
EMS ecu Freeze (Do not activate)
IMV current trim fault.
3.
EMS ecu Increases idle target
speed.
4.
Apply reduce torque 1 mode:(60%
of torque) or reduce torque
mode:(80% of torque).
5.
EMS ecu disable's SPC (Speed
Pilot Control) strategy, no more
SPC trim update.
6.
EMS ecu disables the AFR
controller.
7.
MI Lamp light on & Display
message on IC shows: Engine
system fault.
8.
EMS ecu disables cruise control
function.
9.
EMS ecu disables RVD on injector
Cylinder 2.
10.
EMS ecu Enters into SPC (Speed
Pilot Control) extended mode
(wider area…).
11.
EMS ecu disables IMV resistance
estimation.
1.
Check injector connector; Key off ignition and wait for 20
seconds. Disconnect the injector clean and reconnect properly.
Check if problem vanishes.
2.
Perform Injector cylinder 2 actuator test with the help of I/O
control command of injector cylinder 2. If this test fails then it
is confirmed that there is some issue with either injector wiring
harness/Injector itself.
3.
Check the wiring harness resistance between the Injector
cylinder 2 connector pin 2 and EMS ECU pin A74, the
resistance value should be less than 0.15 ohm. Check the
wiring harness resistance between the Injector cylinder 2
connector pin 1 and EMS ECU pin A50, the resistance value
should be less than 0.15 ohm. If the resistance found is out of
range then replace wiring harness of injector. Check the
resistance between two injector terminals it should be less
than 0.322 ohms.
4.
Check for fault codes - P0202 or P0266 or P2147 or P2148. If
any of these faults appear then resolve these faults by
following thier rectification procedure.
5.
Replace injector cylinder 2 wiring harness if probblem still
persists.
6.
Replace injector if problem still persists.
7.
Replace ECU if problem still persists.

Engine Coolant
Temperature Sensor 2
Circuit SC to Vbatt
This fault gets logged if the coolant drive
output pin of EMS ecu is SC to GND
EMS ECU takes following recovery
actions::~
1.
Disables the AMF sensor learning.
2.
Disables the AMF plausibility test.
3.
Disables EGR control and close
EGR valve.
4.
Disables SPC (Speed Pilot
Control) strategy, no more SPC
trim update.
5.
Coolant temperature indication on
Instrument cluster will not
function.
1.
Check electrical continuity between EMS ECU pin 235 to
Dashboard cluster connector as per circuit schematic; follow
electrical continuity check procedure, Replace/rectify harness
if required.
2.
Check whether the EMS ecu pin 235 is short circuited to
Battery Supply.
3.
Check whether any other faults are present in EMS. If so,
rectify them by following their rectification procedure.
4.
If fault still persists then check whether EMS ecu is getting
Power supply and ground connections.
5.
Confirmatory check after rectification Check if no other faults /
DTC's are present in EMS ecu: Crank the vehicle, Press the
accelerator pedal and check whether the coolant indication on
Instrument cluster is varying as per the Coolant temperature.
