Suzuki Grand Vitara JB416 / JB420 / JB419. Manual — part 307

5A-19 Automatic Transmission/Transaxle:

Step 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 a inspection form will facilitate collecting information to the point required for proper
analysis and diagnosis.

Customer problem inspection form (example)

10 ) Check for intermittent problem

1) Check for intermittent problem.

Is there any faulty condition?

Repair or replace

I5JB0A510015-01

Automatic Transmission/Transaxle: 5A-20

NOTE
The form is a standard sample. It should be modified according to conditions characteristic of each
market.

Step 2. DTC / Freeze Frame Data Check, Record and
Clearance
First, referring to “DTC Check”, 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”. 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 Step 4. Visual Inspection
As a preliminary step, be sure to perform visual check of
the items that support proper function of the A/T and
engine referring to “Visual Inspection”.

Step 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, Record and

Clearance”.
Also, recheck DTC according to “DTC Confirmation
Procedure” described in each DTC flow.

Step 6 and Step 7. Recheck and Record of DTC /
Freeze Frame Data
Refer to “DTC Check” for checking procedure.

Step 8. A/T Basic Check and A/T Trouble Diagnosis
Perform A/T basic check according to “A/T Basic Check”
first. When the end of the flow has been reached, check
the parts of the system suspected as a possible cause
referring to “A/T Symptom Diagnosis” and based on
symptoms appearing on the vehicle (symptoms obtained
through steps of customer complaint analysis, trouble
symptom confirmation and/or A/T basic check) and
repair or replace faulty parts, if any.

Step 9. Troubleshooting for DTC
Based on the DTC indicated in Step 6 and 7 and
referring to applicable DTC flow, locate the cause of the
trouble, namely in a sensor, switch, wire harness,
connector, actuator, TCM 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 A/T
is free from any abnormal conditions.
If what has been repaired is related to the malfunction
DTC, clear the DTC once, set conditions under which
DTC was detected and A/T and/or vehicle was repaired
and confirm that no DTC is indicated.

Malfunction Indicator Lamp (MIL) Check

S6JB0A5104002

Refer to “Malfunction Indicator Lamp (MIL) Check: For
Petrol Engine Model in Section 1A”.

Transmission Warning Light Operation Check
(Non-E-OBD Model)

S6JB0A5104003

1) Turn ignition switch ON.
2) Check that transmission warning light lights for about

2 – 4 sec. and then goes OFF. If anything faulty is
found, advance “Transmission Warning Light Circuit
Check – Light Does Not Come “ON” at Ignition
Switch ON (Non-E-OBD Model)” or “Transmission
Warning Light Circuit Check – Light Remains “ON” at
Ignition Switch ON (Non-E-OBD Model)”.

“POWER” Lamp Operation Check

S6JB0A5104004

1) Turn ignition switch ON.
2) Check that “POWER” lamp lights for about 2 – 4 sec.

and then goes OFF.
If anything faulty is found, advance to ““POWER”
Light Circuit Check – Light Does Not Come “ON” at
Ignition Switch ON”.
