WARNING

!

 

When performing a driving test, select a safe place where there is neither any traffic nor any traffic 
accident possibility and be very careful during testing to avoid occurrence of an accident.

 

After repair or replace malfunction part(s), clear all DTCs by performing the following procedure or using SUZUKI scan 
tool.

1) Connect SUZUKI scan tool to data link connector in the same manner as when making this connection for DTC 

check.

2) Turn ignition switch to ON position.
3) Erase DTC according to instructions displayed on scan tool. Refer to scan tool operator’s manual for further 

derails.

NOTE
For DTC C 1021, C1022, C1025, C1026, C1031, C1032, C1035, C1036 and C1061, confirm that ABS 
warning lamp turns off after performing Step 2 of “Test Driving” under “Electronic Stability Program 
Check”, 
and then clear the DTCs.

 

4) After completing the clearance, turn ignition switch OFF and disconnect scan tool from data link connector.
5) Perform “Driving Test” (Step 2 of “Electronic Stability Program Check”) and “DTC Check” and confirm that NO DTC 

is displayed on scan tool.
