“A” Low.
M
1. MIL is ON.
2. Possible Loss of power / black smoke.
3. EGR is disabled.
This DTC gets logged if OC
or SC to GND is detected in
EGR vacuum modulator
circuit.
1. Check the EGR -EVRV
connection.
2. Check electrical continuity.
3. Check ECU.
1. Check the EGR vacuum modulator connection;
Rectify/ Replace EGR modulator connections if
required.
2. Check continuity between ECU pin 45 and EGR
modulator as per circuit schematics. Check whether
the ecu pin 45 is short circuited to ground if so, and
then rectifies the wiring harness connections.
3. Ensure EGR modulator connector on wiring
harness is connected to EGR modulator.
4. Check EGR – modulator functioning if necessary
replace the EGR – modulator.
5. Check ECU; if problem still persist; replace ECU.
6. Confirmatory check after rectification Perform
actuator test for EGR drive.

1. MIL is ON.
2. Possible Loss of power / black smoke
3. EGR is disabled.
This DTC gets logged if SC
to Supply is detected in
EGR vacuum modulator
circuit.
1. Check the EGR -EVRV
connection.
2. Check electrical continuity.
3. Check ECU.
1. Check the EGR vacuum modulator connection;
Rectify/ Replace EGR modulator connections if
required.
2. Check continuity between ECU pin 45 and EGR
modulator as per circuit schematics. Check whether
the ecu pin 45 is short circuited to battery if so, then
rectify the wiring harness connections.
3. Ensure EGR modulator connector on wiring
harness is connected to EGR modulator.
4. Check EGR – modulator functioning if necessary
replace the EGR – modulator.
5. Check ECU; if problem still persist; replace ECU.
6. Confirmatory check after rectification. Perform

nce.
M
1. Possibly No ODO/Speedo Display.
2. Signal loss from Odometer to ECU.
3. EGR is disabled
4. Injector learning strategy is deactivated;
MDP Updating is deactivated
5. Reduced torque mode [Restricted
performance]
6. This DTC will cause P0500 getting
registered.
This DTC gets logged if the
ECU does not receive
vehicle speed signal. This
DTC will get logged only
under vehicle driving
condition; when all the
following conditions are met
at the same time,
a). No vehicle speed
signal from odometer
cluster to ECU.
b) Engine speed exceeds
2000 rpm.
c) Indicated torque
exceeds 200 Nm.
A. For Non-ABS vehicle.
1. Confirm vehicle speed is
displayed in dash board. If
not check continuity from
Vehicle speed sensor to
dashboard.
2. Check Vehicle speed
sensor.
3. Check dashboard cluster.
4. Check intermediate
connector for continuity.
5. Check connector pins for
rust; dirt formation etc.
B. For ABS vehicles check
for ABS ECU related Faults.
1. Check and confirm vehicle speed is displayed in
dash board. If not check continuity from Vehicle
speed sensor to dashboard.
2. Check Vehicle speed sensor availability /
damage; Replace Vehicle speed sensor if faulty.
3. Check continuity between dashboard clusters to
ECU pins 33, 59 as per circuit schematic.
4. Check dashboard cluster; Replace Dashboard
cluster if faulty.
5. Check intermediate connector for continuity;
Repair/ rectify the connectors
6. Check connector pins for rust; dirt formation etc.;
clean the connectors to remove rust etc.
7. Check ECU; Replace ECU if problem still
persists.
8. Final check for reconfirmation drive the vehicle at
from 0 to 100 kmph and cross check the vehicle
speed shown by ECU against speedo meter; the
readings should be close to each other.
