Component internal failure
This fault gets logged when pedal track
1 and pedal track 2 failures are
confirmed.
1.
EMS ECU disables RBM inc.
2.
EMS ECU Applies specific idle
target for limp home.
3.
EMS ECU Disables cruise control
function.
4.
EMS ECU Disables dTI iso leak
test, DTI iso IMV test & DTI HPV
iso test.
5.
EMS ECU Applies specifi idle
target for limp home.~
1.
Check for any faults related to accelerator pedal track 1 and
track 2: P0123-12, P0122-14, P0223-12, and P0222-14 &&
reference voltage faults: P0641, P0651; if noticed Rectify the
concerned faults by following their rectification procedure.
2.
Check Electrical continuity between ECU pins B25,B24 & B26
to Pedal connector pins 4,2 & 3 && ECU pins B13,B29, &
B14 to pedal connector pins 6,1 & 5 as per circuit schematics;
Follow Electrical continuity check procedure. Replace/ rectify if
any faults found.
3.
After rectification ensure the following checks before handing
over the vehicle to customer.
A) When pedal is not pressed - Pedal position in tata
diagnostic tool should be less than 5%.
B) When the pedal is fully pressed - Pedal position in tata
diagnostic tool should be more than 95 %.

Performance or Incorrect
Operation
This fault gets logged if the rail pressure
is not building after Ignition on when the
fuel tank level is Normal or low.
EMS ECU
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
relay is functioning properly. Replace if found faulty.
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 rail pressure sensor connectors for
