FAIL SAFE FUNCTION
This function is provided by the safe mechanism that assures safe driveability even when the solenoid valve,
sensor or its circuit fails.
The table below shows the fail safe function for each fail condition of sensor, solenoid or its circuit.

[INTERMITTENT TROUBLES] and [NOTES ON SYSTEM CIR-
CUIT INSPECTION]
Refer to Section 0A.
DTC CHECK
[Check DTC with SUZUKI scan tool]
1) Turn ignition switch OFF.
2) After setting cartridge, connect SUZUKI scan tool to data link
connector (DLC) (1) located on underside of instrument
panel at driver’s seat side.
Special tool
(A) : 09931-76011 (SUZUKI scan tool)
(B) : Mass storage cartridge
(C) : 09931-76030 (16/14 pin DLC cable)
3) Turn ignition switch ON.
4) Read DTC according to instructions displayed on SUZUKI
scan tool and print it or write it down. Refer to SUZUKI scan
tool operator’s manual for further details.
5) After completing the check, turn ignition switch OFF and dis-
connect SUZUKI scan tool from data link connector (DLC)
(1).
[Check DTC without SUZUKI scan tool]
1) Turn ignition switch ON and make sure that O/D OFF lamp is
OFF in combination meter (O/D off switch OFF).
2) Turn ignition switch OFF.
3) Pull out clip (3) and remove glove box (2) from instrument
panel (1).

DTC CLEARANCE
[Clear DTC with SUZUKI scan tool]
1) Turn ignition switch OFF.
2) After setting cartridge to scan tool, connect it to data link
connector (DLC) (1) located on underside of instrument
panel at driver’s seat side.
Special tool
(A) : 09931-76011 (SUZUKI scan tool)
(B) : Mass storage cartridge

SHIFT LOCK SOLENOID MANUAL RLEASE
Without using brake pedal, shift lock can be moved by pushing
shift lock solenoid cam (1) with screw driver or like through hole
(2). (To shift selector lever from “P” range to any other position,
turn ignition switch to “ACC” or “ON” position.)
INSPECTION
1) Check to make sure that selector lever cannot be moved to
any other range from “P” range position when ignition switch
key is at “ACC” position, at “LOCK” position (or it is removed
from keyhole of ignition switch) or brake pedal is not
depressed.
2) Shift selector lever to “P” range position, release knob button
and check for the following.
Ignition key can be turned between “LOCK” and “ACC” posi-
tions back and forth and also it can be removed from ignition
switch.
With shift lock solenoid cam (1) moved in arrow direction and
ignition key turned to “ACC” position, selector lever can be
shifted from “P” range position to any other range.
With shift lock solenoid cam moved in arrow direction and
ignition key turned to “LOCK” position, selector lever can not
be shifted from “P” range position to any other range.

3) If selector lever is in “P” range, shift selector lever to other
than “P” range with releasing shift lock referring to “SHIFT
LOCK SOLENOID MANUAL RELEASE” in this section.
4) Install cable end (1) and cable casing cap (2) to key interlock
cam (3) and its bracket (4), then install cable (5) to selector
pad (6).
5) With selector lever set at “P” position, turn ignition key to
“ACC” position and then check for following conditions.
With knob button released, ignition key can be turned from
“ACC” position to “LOCK” position.
With knob button pressed, ignition key cannot be turned from
“ACC” position to “LOCK” position.
6) Install steering column referring to Section 3C.
7) Install steering column hole cover.
8) Install center console.
9) Connect negative cable at battery and enable air bag sys-
tem, referring to “ENABLING AIR BAG SYSTEM” in Section
10B (if equipped).
