4F-16 Electronic Stability Program:

NOTE

• “{” in ABS warning lamp, EBD warning lamp and ESP

® warning lamp column of the above table

means warning lamp is lit when DTC is detected.

• *1: If two or more wheel speed sensor are defective, ABS warning lamp, EBD warning lamp and

ESP

® warning lamp are lit and all the control functions are deactivated. If one wheel speed sensor is

defective, ABS warning lamp and ESP

® warning lamp are lit and ABS and TCS / stability control are

deactivated.

• *2: For 4WD vehicle, ABS warning lamp and ESP

® warning lamp are lit and ABS and TCS / stability

control are deactivated. For 2WD vehicle, ESP

® warning lamp is lit and TCS / stability control is

deactivated.

• *3: SLIP indicator lamp and ESP

® OFF lamp turn ON when power supply circuit voltage is low.

• *4: SLIP indicator lamp flashes continuously at Intervals of 1 Hz.
• *5: EBD warning lamp is lit when power supply circuit voltage is too low.

DTC Clearance

S5JB0E4604006

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 “D TC Check” and confirm that NO DTC

is displayed on scan tool.
