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

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”.
