Hyundai Tiburon (2003 year). Manual — part 90

No wheel speed sensor output signal.

• Malfunction of wheel speed sensor

• Improper installation of wheel speed sensor

• Malfunction of rotor (excitor)

• Malfunction of wiring harness or connector

• Malfunction of HECU

DTC No. C1101, C1102 Voltage out of range
(Low and over voltage)

Probable cause

The voltage of the HECU power supply drops lower than or
rises higher than the specified value. If the voltagereturns to
the specified value, this code is no longer output.

• Malfunction of wiring harness or connector

• Malfunction of HECU.

If battery voltage drops or rises during inspection, this code will be output as well. If the voltage returns to the standard
value, the code is no longer output. Before carrying out the followinginspection, check the battery level, and refill if
necessary.

DTC No. C1604 HECU Hardware
(EEPROM and ECU failure)

Probable cause

The HECU always monitors the solenoid valve drive circuit. It
determines that there is an open or short-circuit in the
solenoid coil or in a harness even if no current flows in the
solenoidor through the HECU.

• Malfunction of wiring harness

• Malfunction of HECU

DTC No. C2112 Valve relay
(Including fuse failure)

Probable cause

When the ignition switch is turned ON, the HECU switches
the valve relay on and off during its initial check. During this
time, voltage sent to the valve relay is compared to the
voltage in the valve power monitor line. If no current is
detected in the valve power monitor line, the HECU
determines that there is an open circuit and DTC C2112is
recorded.

• Malfunction of wiring harness or connector

• Malfunction of HECU

DTC No. C1605 CAN hardware error

Probable cause

Replace the HECU.

• Interference by means of electronic wave

• Mismatching of the calculation between main and sub

processor

• Defects of the valve coil and valve coil operating circuit

element

DTC No. C1611 CAN timeout EMS, C1612 CAN timeout
TCU, C1613 CAN wrong matched transmission

Probable cause

Inspect the EMS or TCU according to the instructions of
Engine or T/M group.

• No message from EMS or TCU for 500ms

• Message from A/T or M/T signal mismatch the message

from ECM or TCU

DTC No. C1610 bus off error

Probable cause

Check CAN bus wiring.
Check E37, C33, C133-4 or M42 connectors

• CAN bus cable open, or short to ground or battery

DTC No. C2402 motor pump failure
(Motor relay, motor)

Probable cause

When the motor power line is normal but no signal is in
detected in the motor monitor line.

• Malfunction of wiring harness

• Malfunction of HECU

Powering the motor with the Hi-Scan (Pro) will discharge the battery. Start and run the engine for a while after testingis
complete.

BLEEDING OF BRAKE SYSTEM

1. Remove the reservoir cap and fill the brake reservoir with brake fluid.

If there is any brake fluid on any painted surface, wash it off immediately.

When pressure bleeding, do not depress the brake pedal.
Recommended fluid . . . DOT3 or DOT4

2. Connect a clear plastic tube to the wheel cylinder bleeder plug and insert the other end of the tube into a half

filled clear plastic bottle.

3. Connect the Hi-Scan (Pro) to the Data Link Connector located underneath the dash panel.

4. Select and operate according to the instructions on the Hi-Scan (Pro) screen.

You must obey the maximum operating time of the ABS motor with the Hi-Scan (Pro) to prevent the
