Abs(Anti-Lock Brake System) Diagnostic Trouble Code (Dtc); Abs(Anti-Lock Brake System) Self-Diagnosis; How To Troubleshoot Abs Dtc; Hi-Scan (Pro) Check - Hyundai Tiburon 2003 Workshop Manual

The EBD warning lamp is turned on under the following conditions.
A. During the initialization phase after ignition switch ON. (3 seconds).
B. When the system ECU is shut down even though ignition power is applied.
C. When the parking brake switch is ON or brake fluid is low level.
D. In the event of inhibition of EBD functions by failure.
3. TCS lamp module
The TCS warning lamp module indicates the operating condition of the TCS.
The TCS warning lamp is turned on under the following conditions:
A. During the initialization phase after ignition switch ON (3 seconds).
B. In the event of inhibition of TCS functions by failure.
C. When the TCS OFF switch is turned on.
TCS function lamp is turned on when the TCS functions are operating (Blinking-2Hz).
Diagnostic trouble code (DTC)
1. If the CPU cannot be activated or the CPU fails, the ABS indicator comes on, but the DTC is not memorized.
2. The memory can hold any number of DTCs. However, when the same DTC is detected more than once, the later one is
written over the old one.
Therefore, when the same problem is detected repeatedly, it is memorized as one DTC.
3. The DTCs are indicated in the order they occur.
4. The DTCs are memorized in the EEPROM (non - volatile memory). Therefore, the memorized DTCs cannot be
canceled by disconnecting the battery. Perform the specified procedures to erase the DTCs.
Self-diagnosis
1. Self diagnosis can be classified into two categories:
A. Initial diagnosis:
Performed right after the engine starts and until the ABS indicator goes off.
B. Regular diagnosis:
Performed right after the initial diagnosis until the ignition switch is turned OFF.
2. When a problem is detected by self-diagnosis, the system:
A. Turns the solenoid valve OFF
B. Turns the pump motor OFF
C. Turns the ABS indicator ON

How to troubleshoot ABS DTC

1. Question the customer about the conditions when the problem occured, and try to reproduce the same conditions for
troubleshooting. Find out when the ABS indicator came on, such as during initial diagnosis, during ABS control, after
ABS control, when vehicle speed was at a certain speed, etc.
2. When the ABS indicator does not come on during the test-drive, but troubleshooting is performed based on the DTC.
check for loose connectors, poor contact of the terminals, etc. before you start troubleshooting.
3. After troubleshooting, erase the DTC and test-drive the vehicle. Be sure the ABS indicator does not come on.

HI-SCAN (PRO) CHECK

1. Turn the ignition switch OFF.
2. Connect the Hi-scan (pro) to the 16P data link connector located underneath the lower crash pad panel.
