Malfunction Indicator Lamp (Mil) Check - Suzuki Grand Vitara 2011 Manual

Step 2: DTC / Freeze Frame Data Check, Record and
Clearance
First, check DTC (including pending DTC), referring to
"DTC Check: For Petrol Engine Model". If DTC is
indicated, print it and freeze frame data or write them
down and then clear them by referring to "DTC
Clearance: For Petrol Engine Model". DTC indicates
malfunction that occurred in the system but does not
indicate whether it exists now or it occurred in the past
and the normal condition has been restored now. To
check which case applies, check the symptom in
question according to Step 5 and recheck DTC
according to Step 6 and 7.
Attempt to diagnose a trouble based on DTC in this step
only or failure to clear the DTC in this step will lead to
incorrect diagnosis, trouble diagnosis of a normal circuit
or difficulty in troubleshooting.
Step 3 and 4: Visual Inspection
As a preliminary step, be sure to perform visual check of
the items that support proper function of the engine
referring to "Visual Inspection: For Petrol Engine Model".
Step 5: Trouble Symptom Confirmation
Based on information obtained in "Step 1: Customer
Complaint Analysis: For Petrol Engine Model" and "Step
2: DTC / Freeze Frame Data Check, Record and
Clearance: For Petrol Engine Model", confirm trouble
symptoms. Also, reconfirm DTC according to "DTC
Confirmation Procedure" described in each DTC diag.
flow.
Step 6 and 7: Rechecking and Record of DTC /
Freeze Frame Data
Refer to "DTC Check: For Petrol Engine Model" for
checking procedure.
Step 8: Engine Basic Inspection and Engine
Symptom Diagnosis
Perform basic engine check according to "Engine Basic
Inspection: For Petrol Engine Model" first. When the end
of the flow has been reached, check the parts of the
system suspected as a possible cause referring to
"Engine Symptom Diagnosis: For Petrol Engine Model"
and based on symptoms appearing on the vehicle
(symptoms obtained through steps of customer
complaint analysis, trouble symptom confirmation and/or
basic engine check) and repair or replace faulty parts, if
any.

Step 9: Troubleshooting for DTC (See each DTC
Diag. Flow)
Based on the DTC indicated in Step 6 or 7 and referring
to the applicable DTC diag. flow, locate the cause of the
trouble, namely in a sensor, switch, wire harness,
connector, actuator, ECM or other part and repair or
replace faulty parts.
Step 10: Intermittent Problems Check
Check parts where an intermittent trouble is easy to
occur (e.g., wire harness, connector, etc.), referring to
"Intermittent and Poor Connection Inspection in Section
00" and related circuit of DTC recorded in Step 2.
Step 11: Final Confirmation Test
Confirm that the problem symptom has gone and the
engine is free from any abnormal conditions. If what has
been repaired is related to the DTC, clear the DTC once,
perform DTC confirmation procedure and confirm that no
DTC is indicated.

Malfunction Indicator Lamp (MIL) Check

1) Turn ON ignition switch (with engine at stop) and
check that MIL (1) lights.
If MIL does not light up (or MIL dims) but engine can
be starting, go to "Malfunction Indicator Lamp Does
Not Come ON with Ignition Switch ON and Engine
Stop (but Engine Can Be Started): For Petrol Engine
Model" for troubleshooting.
If MIL does not light with ignition switch ON and
engine does not start though it is cranked up, go to
"ECM Power and Ground Circuit Check: For Petrol
Engine Model".
2) Start engine and check that MIL turns OFF.
If MIL remains ON and no DTC is stored in ECM, go
to "Malfunction Indicator Lamp Remains ON after
Engine Starts: For Petrol Engine Model" for
troubleshooting.
