Glow Plug lamp short
circuit to VBatt fault
This DTC gets logged due to short
circuit to VBatt fault of the glow plug
lamp driver output of EMS ecu
Start ability problem. (Torque
increase during start up if start fails).
1.
Check electrical continuity between EMS ECU pin 241 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 241 is SC to Battery supply.
3.
Check whether any other faults related to Glow plug 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: Check whether the
Glow Plug lamp indication is ON during bulb check at Ignition
ON and going OFF after 3 sec of Ignition ON.

Glow Plug lamp Open
Circuit fault
This DTC gets logged due to open
circuit fault of the glow plug lamp driver
output of EMS ecu
Start ability problem. (Torque
increase during start up if start fails).
1.
Check electrical continuity between EMS ECU pin 241 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 XX is SC to Battery supply /
Ground.
3.
Check whether any other Glow Plug related 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: Check whether the
Glow Plug lamp indication is ON during bulb check at Ignition
ON and going OFF after 3 sec of Ignition ON.

Circuit Short to ground
This fault gets logged if the 2H mode
switch input pin of EMS ecu is short
circuited to ground.
1.
4L lamp will be continuously ON.
2.
Torque limitation will be active
1.
Check the continuity between the EMS ecu Pin 240, 215 and
152 of EMS ecu to Drive mode selector rotary switch
connector.
2.
Check whether the the EMS pins 240 is Short circuited to
Ground. If so, rectify the wiring harness connections as per the
schematic.
3.
Check whether the EMS pins 240, 215 and 152 are short
circuited between each other. If so, rectify the wiring harness
connections as per the schematic.
4.
Check for any faults in ESOF ecu and rectify them by following
their rectification procedure.
5.
If fault still persists then replace the mode selector switch.
6.
Repeat the above procedure for reconfirmation.
