PCM malfunction.
DTC CONFIRMATION PROCEDURE
WARNING:

When performing a road test, select a place where there is no traffic or possibility of a traffic accident
and be very careful during testing to avoid occurrence of an accident.

Road test should be carried out with 2 persons, a driver and a tester, on a level road.
1) Turn ignition switch OFF and then ON.
2) Clear DTC and warm up engine to normal operating temperature.
3) Shift selector lever to each of P, R, N, D, 2 and L ranges and hold it there for longer than 5 seconds each.
4) Check for DTC and if no DTC appears on display, proceed to the next step.
5) Drive vehicle at 40 mph, 60 km / h or more in 3rd gear of “D” range for longer than 5 sec.
6) Stop vehicle and check DTC.

2Check Transmission Range Sensor Circuit for Operation.
When using SUZUKI scan tool:
1) Connect SUZUKI scan tool to DLC with ignition switch OFF.
2) Turn ignition switch ON and check transmission range
signal (P, R, N, D, 2 or L) on display when shifting manual
selector to each range. See Fig. 1.
Is applicable range indicated?
When not using SUZUKI scan tool:
1) Turn ignition switch ON.
2) Check voltage at terminals C03-3, C03-4, C03-5, C03-14,
C03-15 and C03-16 for G10 engine model (C02-11, C02-12,
C02-14, C02-15, C02-21 and C02-23 for G13 engine model)
respectively with selector lever shifted to each range. See Fig. 2.
Taking terminal C03-3 for G10 engine model (C02-11 for G13
engine model) as an example, is battery voltage indicated only
when selector lever is shifted to “2” range and 0 V for other
ranges as shown in Fig. 3?
Check voltage at other terminals likewise, referring to Fig. 3.
Are check results satisfactory?Intermittent
trouble. Check
for intermittent
referring to
“INTERMITTENT
AND POOR
CONNECTION”
in Section 0A.Go to Step 3.
3Check Select Cable for Adjustment referring to “SELECT
CABLE” of “ON-VEHICLE SERVICE” in this section.
Is it adjusted correctly?Go to Step 4.Adjust.
4Check Transmission Range Sensor.
1) Remove TR sensor from A / T.
2) At each of P, R, N, D, 2 and L shift position, check continuity
between terminals as well as each terminal and sensor
case. See Fig. 4.
Continuity should be indicated only between those
terminals as shown in Fig. 4 and 5 at each shift position.
Continuity should not exist between any terminal and
sensor case.
Are check results satisfactory?Go to Step 5.Replace TR
sensor.
5Check Transmission Range Sensor for Installation Position.
1) Install TR sensor to transmission referring to
“TRANSMISSION RANGE SENSOR” of “ON-VEHICLE
SERVICE” in this section.
2) Perform check as described in step 2 of this table.
Is check result satisfactory?Transmission
range sensor
maladjusted.Check “Y”, “Or / B”,
“R”, “Or / Y”,
“Gr / R”, “Gr” or
“Gr / Bl” (G10

connections are
OK, substitute a
known-good PCM
and recheck.

DTC CONFIRMATION PROCEDURE
WARNING:

When performing a road test, select a place where there is no traffic or possibility of a traffic accident
and be very careful during testing to avoid occurrence of an accident.

Road test should be carried out with 2 persons, a driver and a tester, on a level road.
1) Turn ignition switch OFF and then ON.
2) Clear DTC, shift selector lever to “2” range and drive vehicle at 3500 r / min engine speed for 3.5 seconds.
3) Stop vehicle and check DTC.

TYPE 1 TYPE 2
BODY ELECTRICAL SYSTEM 8-3
KEYLESS ENTRY SYSTEM (IF EQUIPPED)
The keyless entry system uses radio wave. When the button on the transmitter is pressed, a signal is transmitted
in the form of radio wave to the receiver. Then the signal causes the door lock controller to lock and unlock the door.
The door locks can not operated with the transmitter when either of the following conditions applies.

For 2 seconds after the ignition switch is turned from ON to OFF position.

The ignition switch is at ON or START position.

Any door is open.

INSPECTION
1) Warm up ECT sensor (1) observing resistance between sensor
terminal (2) and sensor unit (1). Resistance should be de-
creased with increase of its temperature.
2) Check resistance between sensor terminal (2) and sensor unit
(1). If check result is not as specified below, replace sensor.

Ignition signal

With the diagnosis switch terminal of monitor coupler for ECM not
grounded, the ignition switch turned ON (but the engine at stop) and
regardless of the condition of the engine and emission control sys-
tem, ECM indicates whether a trouble has occurred in the immobi-
lizer control system or not by causing the malfunction indicator lamp
to flash or turn ON.
Malfunction indicator lamp is ON:
No trouble exists in the immobilizer control system.
Malfunction indicator lamp is flashing:
ECM or Immobilizer Control Module has detected some trouble in
the immobilizer control system.
NOTE:
As soon as the ignition switch is turned ON, ECM and Immobi-
lizer Control Module diagnose if a trouble has occurred in the
immobilizer control system. While the diagnosis is being
made, the malfunction indicator lamp stays ON and if the diag-
nosis result is “abnormal”, it immediately changes to flashing
but if the result is “normal”, it remains ON. Diagnosis takes
about 3 seconds at maximum.
