Injection Warning Light Does Not Come On With Ignition Switch On And Engine Stop - Suzuki Grand Vitara 2011 Manual

10C-37 Immobilizer Control System: For Diesel Engine Model

Injection Warning Light Does Not Come ON with Ignition Switch ON and Engine Stop

Wiring Diagram
Refer to "Immobilizer Control System Wiring Circuit Diagram: For Diesel Engine Model".
Circuit Description
When the ignition switch is turned ON, ECM transmits the indication ON signal to the combination meter to turn ON the
injection warning light in case that there is not any problem with the immobilizer control system. Then, the combination
meter turns ON the light. When the engine is started up, ECM transmits the indication OFF signal to the combination
meter to turn OFF the light. Then, the combination meter turns OFF the injection warning light. However, in case that
there is some trouble with the immobilizer control system, the injection warning light flashes ON and OFF when the
ignition switch is turned ON.
Troubleshooting
Step
1 Injection warning light power supply check
1) Turn the ignition switch to ON position.
Do other warning lights come ON?
2 Diagnostic Trouble Code (DTC) check
1) Check ECM for DTC referring to "DTC Check: For Diesel
Engine Model in Section 1A".
2) Check ABS control module or ESP
DTC. For ESP
4F". For non-ESP
Section 4E".
3) Check BCM for DTC referring to "DTC Check in Section
10B".
Is any DTC(s) detected?
3 Fuse check
1) Turn the ignition switch to OFF position.
2) Check if any related fuse is blown.
Is any fuse blown?
4 Combination meter power supply wire circuit check
1) Remove combination meter referring to "Combination
Meter Removal and Installation in Section 9C".
2) Check for proper connection at wire terminals of
combination meter connector.
3) If OK, turn the ignition switch to ON position and
measure voltage between power supply terminal of
combination meter and vehicle body ground referring to
"Combination Meter Circuit Diagram in Section 9C".
Is it 10 – 14 V?
5 Combination meter ground wire circuit check
1) Turn ignition switch OFF position.
2) Measure resistance between ground terminal of
combination meter connector and vehicle body ground
referring to "Combination Meter Circuit Diagram in
Section 9C".
Ω
Is resistance 1 or less?

Go to Step 2.
Go to applicable DTC
diag. flow.
Replace blown fuse,
and then check for
short.
Go to Step 5.
Replace combination
meter with a know-good
one and recheck. If the
injection warning light
still remains OFF,
replace ECM with a
known-good one and
recheck.

No
Go to Step 3.
Replace combination
meter with a known-
good one and recheck.
If the injection warning
light still remains OFF,
replace ECM with a
known-good one and
recheck.
Go to Step 4.
Repair open in power
supply wire circuit.
Repair open or high
resistance in ground
wire circuit.
