OUTPUT SHAFT SPEED SENSOR (A / T VSS)
The output shaft speed sensor consists of a magnetic core with
magnet and coil. It is mounted on transmission case with 0.6 mm
(0.024 in.) air gap between the core end and countershaft gear
tooth.
While the countershaft rotates, magnetic flux is cut by gear tooth
thus a pulse is generated in the sensor coil according to the speed.
And then, the pulse is transmitted to engine control module as
speed signal.
AUTOMATIC SHIFT DIAGRAM
Automatic shift schedule as a result of shift control is shown below. In case that selector lever is shifted to L range
at a higher than 37 km / h (23 mile / h) (G10 engine model), 40 km / h (25 mile / h) (G13 engine model) speed, 2nd
gear is operated and then down shifts to 1st at a speed lower than that. No up shift is available in L range.

PRECAUTION IN DIAGNOSING TROUBLE

Don’t disconnect couplers from PCM, battery cable from battery, PMC ground wire harness from engine or main
fuse before checking the diagnosis information (DTC, freeze frame data, etc.) stored in PCM memory.
Such disconnection will clear memorized information in PCM.

Using SUZUKI scan tool (Tech-1) the diagnostic information stored in PCM memory can be checked and cleared
as well. Before its use, be sure to read Operator’s (instruction) Manual supplied with it carefully to have good
understanding of its functions and usage.

Priorities for diagnosing troubles
If two or more diagnostic trouble codes (DTCs) are stored, proceed to flow table (chart) of DTC which was de-
tected earliest in order and follow instruction in that table (chart).
If no instructions are given, troubleshoot diagnostic trouble codes according to the following priorities.
1. Diagnostic trouble codes (DTCs) other than DTC P0171 / P0172 (Fuel system too lean / too rich), DTC
P0300 / P0301 / P0302 / P0303 / P0304 (Misfire detected) and DTC P0400 (EGR flow malfunction)
2. DTC P0171 / P0172 (Fuel system too lean / too rich) and DTC P0400 (EGR flow malfunction)
3. DTC P0300 / P0301 / P0302 / P0303 / P0304 (Misfire detected)

Be sure to read “PRECAUTION FOR ELECTRICAL CIRCUIT SERVICE” in Section 0A before inspection and
observe what is written there.

PCM replacement
When substituting a known-good PCM, check for following conditions.
Neglecting this check may result in damage to good PCM.
–All relays and actuators have resistance of specified value.
–MAF sensor, TP sensor and fuel tank pressure sensor (if equipped) are in good condition. Also, the power cir-
cuit of these sensors is not shorted to the ground.

1. CUSTOMER COMPLAINT ANALYSIS
Record details of the problem (failure, complaint) and how it occurred as described by the customer.
For this purpose, use of such an inspection form (shown in next page) will facilitate collecting information to
the point required for proper analysis and diagnosis.
2. DIAGNOSTIC TROUBLE CODE (DTC) / FREEZE FRAME DATA CHECK, RECORD AND
CLEARANCE
First, referring to “DTC CHECK” in this section, check DTC (including pending DTC). If DTC exists, print or
write down DTC and freeze frame data and then clear them by referring to “DTC CLEARANCE” in this section.
DTC indicates malfunction in the system but it is not possible to know from it whether the malfunction is occur-
ring now or it occurred in the past and normal condition has been restored. In order to know that, check symp-
tom 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 un-
necessary.
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
and automatic transmission referring to “VISUAL INSPECTION” in this section.
5. TROUBLE SYMPTOM CONFIRMATION
Check trouble symptoms based on information obtained in Step 1 “Customer complaint analysis” and Step
2 “DTC / freeze frame data check”.
Also, reconfirm DTC according to “DTC CONFIRMATION PROCEDURE” described in each “DTC Flow Table”
in this section.
6. and 7. RECHECKING AND RECORD OF DTC / FREEZE FRAME DATA
Refer to “DTC CHECK” in this section for checking procedure.
8. AUTOMATIC TRANSMISSION BASIC CHECK AND SYMPTOM-TO-INSPECTION TABLE
Perform basic check of A / T according to “AUTOMATIC TRANSMISSION BASIC CHECK FLOW TABLE” first.
When the end of the flow table has been reached, check the parts of the system suspected as a possible cause
referring to “SYMPTOM -TO- INSPECTION TABLE” and based on symptoms appearing on the vehicle (symp-
toms obtained through steps of customer complaint analysis, trouble symptom confirmation and / or A / T basic
check) and repair or replace faulty parts, if any.
9. DIAGNOSTIC TROUBLE CODE FLOW TABLE
Based on the DTC indicated in Step 6 and 7, and referring to “DTC Flow Table” in this section, locate the cause
of the trouble, namely in a sensor, switch, wire harness, connector, actuator, PCM or other part and repair or
replace faulty parts.
10. CHECK FOR INTERMITTENT PROBLEM
Check parts where an intermittent trouble is easy to occur (e.g., wire harness, connector, etc.) referring to “IN-
TERMITTENT AND POOR CONNECTION” in Section 0A and related circuit of DTC recorded in step 2.
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 DTC, clear the DTC once, perform DTC confirmation procedure and
check to ensure that no DTC is indicated.
