Circuit short to battery
This fault gets logged under the
following conditions:~
1.
Glow plug is not driven by ECU but
feedback is saying that glow plugs
are on or if the glow plug drive pin in
EMS ECU is short circuited to
Vbatt.~
Glow plug lamp is off.
1.
Check the 40A fuse of glow plug relay 1 and 2, replace if they
are blown off. Check the 30A fuse of EMS ECU main power
relay, replace if it is blown off.
2.
Check continuity between the glow plug drive pin A17 in EMS
ECU to the glow plugs 3 & 4 (as per circuit
schematics).Rectify wiring harness connections in case of
lack of continuity.
3.
Check whether the Glow feedback pin A17 of EMS ECU is
short circuited to Ground. If so, then rectify the wiring harness
connections according to circuit schematics. Check ECU pins
and connector pins for damage/rust. In case of rust then clean
them and refit the connector.
4.
Check whether the Glow plug drive pin of EMS ECU A85 is
short circuited to Battery/open circuited. If so, then rectify the
wiring harness connections according to circuit schematics.
5.
Check whether the resistance of glow plugs is according to
specifications, if not replace the glow plugs.
6.
Replace ECU if problem still persists.

Circuit Open
This fault gets logged if the glow plug
drive pin in EMS ECU is open circuit
EMS ECU disables Xs ramp torque
function (Torque increase during start
up if start fails).
1.
Check continuity between the glow plug drive pin A85 in EMS
ECU to the glow plugs. Rectify wiring harness if any issues
like open circuits are found in the connection circuit of glow
plugs.
2.
Check electrical connections of 2 glow plug relays, if any issues
are found then rectify them according to the circuit
schematics. Check ECU pins and connector pins for
damage/rust. In case of rust then clean them and refit the
connector.
3.
Check glow plugs resistance and replace them resistance is not
according to design specifications (xx to xx ohms).
4.
Replace ECU if problem still persists.
