Event Information
This fault will gets logged if water is
found in fuel and water in fuel lamp will
be lightened.
1.
If ECU detects water existence in
fuel, then it apply reduce torque 1
mode:(60% of torque) as a limp
home action.
1.
Take Drain Sedimentary contents in a bowl and check for water
presence in diesel; if water is present; drain complete fuel from
sedimentary and fuel filter.
2.
Check electrical short circuit in wiring from water sensor to
ECU; Rectify short circuit or replace harness if required.
3.
Check Electrical continuity between ECU to water sedimentary
connector Still If problem persists replace water sedimentary.
4.
Check and replace ECU if still problem persists.

Signal Stuck In Range
This fault gets logged by ECU if the
following condition takes place:-
If the vehicle speed is greater than a
upper threshold limit even when the
brake pedal is pressed.~~ECU will logs
this fault only if the following conditions
are satisfied:~- Engine speed above a
threshold ~- Vehicle speed is above a
threshold ~- P_L_Pedal_position in
stable position ~- P_L_Pedal_position
above a minimum value ~- No brake
pedal information fault~~In order to
avoid wrong failure detection, pedal
stuck fault is frozen(frozen means - soft
fault will be logged but it will not be
shown in diagnostic tool. in case if fault
is shown in diagnostic tool then it will be
resettled) following cases :~- during
accelerator pedal track 2 to ground
test~- if an external torque is detected~-
if a soft or rec failure is detected on both
pedal tracks.
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 specific idle
target for limp home.
1.
Check, if the Brake lights are on even when no brake pedal is
pressed.
2.
Check whether the accelerator pedal is free to move; Ensure
free movement of the pedal; replace pedal if pedal movment is
not free or very hard.
3.
Check the brake switch setting; If the problem is with the brake
setting perform the necessary repairs.
4.
Check Electrical continuity between ECU to Accelerator pedal
connector as per circuit schematics; Check whether the
accelerator pedal input pins of EMS ECU B24,B25,B29 & B13
are Short circuited to battery/ground and ECU pins B26 & B14
are Short circuited to battery supply due to wiring harness
wrong connections. If so then rectify the wiring harness
connections to make them inline with circuit schematics.
5.
Check Electrical continuity between ECU pins B32 & B30 to
Brake pedal connector. if any issues are found then make
connections inline with circuit schematics. Check whether the
brake input pins of EMS ECU B32 & B30 are Short circuited to
battery/ground due to wiring harness wrong connections. If so
then rectify the wiring harness connections to make them inline
with circuit schematics.
6.
Check whether the pedal potentiometer sensors 1 &2
parameter values in diagnostic tool are varying~ inline with
pedal pressing condition. If not check steps 4 & 5 thoroughly,
any issue found then rectify it by modifying wiring harness
connections else replace faulty pedal potentiometer sensor.
7.
Check and replace ECU still problem persists.
8.
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 %.
C) Ensure break ligh is not glowing when the brake pedal is
not pressed.
