Circuit Short To Ground or
Open
This fault gets logged if the Accelerator
pedal sensor 2 signal pin of EMS ECU is
short circuited to ground/open
1.
Applies reduce torque mode:(80%
of torque).
2.
EMS ECU disables dTI iso leak
test, DTI iso IMV test & DTI HPV
iso test.
3.
EMS ECU Increases idle target
speed.
4.
EMS ECU disable cruise control
function.
1.
Check for Sensor reference voltage fault: P0651. If found then
rectify it by following its rectification procedure for solving this
fault.
2.
Check Electrical continuity between ECU pins B13,B29 & B14
to Pedal connector pins 6,1 & 5; Replace/ Rectify if any
faults found.
3.
Check whether Accelerator pedal switch 2 signal pin B13 is
short circuited to ground, if so then rectify the wiring harness
connections to make them inline with circuit schematics.
4.
Replace accelerator pedal sensor 2 if the problem still persists.
5.
Replace EMS ECU if the problem still persists.
6.
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 %.

Circuit Short to Battery
This fault gets logged if the Accelerator
pedal sensor 2 signal pin of EMS ECU is
short circuited to battery
1.
Applies reduce torque mode:(80%
of torque).
2.
EMS ECU disables dTI iso leak
test, DTI iso IMV test & DTI HPV
iso test.
3.
EMS ECU Increases idle target
speed.
4.
EMS ECU disable cruise control
function.~
1. Check for Sensor reference voltage fault: P0651. If found
then rectify it by following its rectification procedure for
solving this fault.
2. Check Electrical continuity between ECU pins B13,B29 &
B14 to Pedal connector pins 6,1 & 5; Replace/ Rectify if
any faults found.
3. Check whether Acclerator pedal switch 2 signal pin B13 is
short circuited to battery, if so then rectify the wiring
harness connections to make them inline with circuit
schematics.
4. Replace accelerator pedal sensor 2 if the problem still
persists.
