ABS/TCS

BASIC INSPECTION 1 BRAKE FLUID AMOUNT, LEAKS, AND BRAKE PADS INSPECTION
1. Check fluid level in the brake reservoir tank. If fluid level is low, refill the brake fluid.
2. Check the brake piping and around the ABS actuator and electric unit (control unit) for leaks. If there is leaking or oozing fluid, check the following items.
- If ABS actuator and electric unit (control unit) connection is loose, tighten the piping to the specified torque and re-conduct the leak inspection to make sure there are no leaks.
- If there is damage to the connection flare nut or ABS actuator and electric unit (control unit) screw, replace the damaged part and re-conduct the leak inspection to make sure there are no leaks.
- When there is fluid leaking or oozing from a part other than ABS actuator and electric unit (control unit) connection, if the fluid is just oozing out, use a clean cloth to wipe off the oozing fluid and re-check for leaks. If fluid is still oozing out, replace the damaged part.
- When there is fluid leaking or oozing at ABS actuator and electric unit (control unit), if the fluid is just oozing out, use a clean cloth to wipe off the oozing fluid and re-check for leaks. If fluid is still oozing out, replace the ABS actuator and electric unit (control unit) body.

CAUTION: ABS actuator body cannot be disassembled.

3. Check the brake pad degree of wear.

BASIC INSPECTION 2 POWER SYSTEM TERMINAL LOOSENESS AND BATTERY INSPECTION
Make sure the battery positive cable, negative cable and ground connection are not loose. In addition, check the battery voltage to make sure it has not dropped.

BASIC INSPECTION 3 ABS WARNING LAMP, TCS OFF INDICATOR LAMP, SLIP INDICATOR LAMP INSPECTION
1. Make sure ABS warning lamp, TCS OFF indicator lamp (when TCS OFF switch is OFF), and SLIP indicator lamp turns ON approximately 1 second when the ignition switch is turned ON. If they do not, check the TCS OFF indicator lamp and then TCS OFF switch. Check CAN communications. If there are no errors with TCS OFF switch and CAN communication system, check combination meter.
2. Make sure the lamp turns off approximately 1 second after the ignition switch is turned on. If the lamp does not turn off, conduct self-diagnosis.
3. With the engine running, make sure TCS OFF indicator lamp turns on and off when TCS OFF switch is turned on and off. If the indicator lamp status does not correspond to switch operation, check the TCS OFF switch system.
4. Make sure ABS warning lamp, TCS OFF indicator lamp, and SLIP indicator lamp turn off 2 seconds after the engine is started. If ABS warning lamp, TCS OFF indicator lamp, and SLIP indicator lamp have not turned off 10 seconds after the engine has been started, conduct self-diagnosis of the ABS actuator and electric unit.
5. After conducting the self-diagnosis, be sure to erase the error memory.
