2. DIAGNOSTIC TROUBLE CODE (DTC) CHECK, RECORD AND CLEAR
To check DTC, refer to Diagnostic Trouble Code(s) Check in this section. When a DTC is indicated by this lamp,
it means existence of a malfunction in the system represented by that code but whether it still exists (current)
or it occurred in the past and has gone (history) is unknown. To know it, clear this DTC once (Refer to DIAGNOS-
TIC TROUBLE CODE CLEARANCE in this section.), perform TEST DRIVE and/or PROBLEM SYMPTOM
CONFIRMATION in this section and then check DTC again as described in DIAGNOSTIC TROUBLE CODE
CHECK. Attempt to diagnose the trouble based on the DTC recorded in this step or failure to clear the DTC in
this step may mislead the diagnosis or make diagnosing difficult. Even after checking the DTC with the SUZUKI
scan tool, diagnosis should be performed according to this flow chart to check TCM for proper self-diagnosis
function.

4. PROBLEM SYMPTOM CONFIRMATION
Check if what the customer claimed in CUSTOMER COMPLAINT ANALYSIS is actually found in the vehicle

if possible.)
When the symptom is not actually found, possibility is:
D The symptom occurs under certain conditions.
