Transfer Position Indicator Operation Check; 4Wd Control System Operation Inspection - Suzuki Grand Vitara 2011 Manual

Step 2. DTC / freeze frame data check, record and
clearance
First, referring to "DTC Check: Motor-Shift Type
(Transfer with Shift Actuator)", check DTC and pending
DTC. If DTC exists, print or write down DTC and freeze
frame data and then clear malfunction DTC(s) by
referring to "DTC Clearance: Motor-Shift Type (Transfer
with Shift Actuator)". Malfunction DTC indicates
malfunction in the system but it is not possible to know
from it whether the malfunction is occurring now or it
occurred in the past and normal condition has been
restored. In order to know that, check symptom in
question according to Step 5 and then recheck DTC
according to Step 6.
Diagnosing a trouble based on the DTC in this step only
or failure to clear the DTC in this step may result in an
faulty diagnosis, trouble diagnosis of a normal circuit or
difficulty in troubleshooting which is otherwise
unnecessary.
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 4WD control
system referring to "Visual Inspection: Motor-Shift Type
(Transfer with Shift Actuator)".
Step 5. Trouble symptom confirmation
Check trouble symptoms based on information obtained
in "Step 1: Customer complaint analysis: Motor-Shift
Type (Transfer with Shift Actuator)" and "Step 2. DTC /
freeze frame data check, record and clearance: Motor-
Shift Type (Transfer with Shift Actuator)".
Also, reconfirm DTC according to "DTC Confirmation
Procedure" described in each DTC flow.
Step 6 and 7. Rechecking and record of DTC and
freeze frame data
Refer to "DTC Check: Motor-Shift Type (Transfer with
Shift Actuator)" for checking procedure.
Step 8. 4WD control symptom diagnosis
Check the parts of the system suspected as a possible
cause referring to "4WD Control Symptom Diagnosis:
Motor-Shift Type (Transfer with Shift Actuator)".
Step 9. Troubleshooting for DTC
Based on the DTC indicated in Step 6 / 7 and referring to
"applicable DTC flow", locate the cause of the trouble,
namely in a sensor, switch, wire harness, connector,
actuator, 4WD control module or other part and repair or
replace faulty parts.
Step 10. Check for intermittent problem
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
vehicle is free from any abnormal conditions. If what has
been repaired is related to the malfunction DTC, clear
the DTC once and check to ensure that no malfunction
DTC is indicated.

Transfer Position Indicator Operation Check

1) Turn ignition switch to OFF position.
2) Check that transfer position indicators turn on for
about 2 seconds and then turns off.
If any faulty condition is found, proceed to "Transfer
Position Indicator Does Not Come ON at Ignition
Switch ON but Engine Stops: Motor-Shift Type
(Transfer with Shift Actuator)" or "Transfer Position
Indicator Remains ON Steady at Ignition Switch ON:
Motor-Shift Type (Transfer with Shift Actuator)".

4WD Control System Operation Inspection

NOTE
• If it is difficult to shift between "4H" and
"4H-lock" while vehicle is moving, stop
vehicle and operate Transfer switch.
• When ABS operates while shifting from
"4H" to "4H-lock" ("4H-lock" to "4H"), it
becomes to disagreement of transfer
switch and transfer position. End of the
ABS operation, and then transfer shifting
from "4H" to "4H-lock" ("4H-lock" to "4H").
• Transfer position indicator blinks during
shifting process.
• Transfer position indicator blinks and
warning buzzer sounds during "N"
position at intervals of 3 seconds.
• When shifting to "N" or "4L-lock" does not
shifts, try the following procedure.
– For M/T model, shift transmission to N
(Neutral) position, turn ignition switch to
ON position, depress clutch pedal and
brake pedal while engine is running, and
then try shifting again.
– For A/T model, turn ignition switch to
ON position, move vehicles lowly back
