C2380

DTC C2380 ABS/TCS/ESC VALVE ERROR

DESCRIPTION
The HECU monitors the solenoid valve operating circuit. If there is no continuity of the solenoid valve, when the HECU switches the solenoid valve ON, it is a cause an open or short in the circuit of the solenoid coil or harness.

DTC DESCRIPTION
This code shows in case that there is an open or short in the circuit of the solenoid coil or harness.

DTC Detecting Condition:

FAIL-SAFE FUNCTION
The system stops. the ABS, TCS (ESC) and the EBD functions are inhibited. The ABS, TCS (ESC) and the EBD warning lamps are ON. The valve relay and all solenoids are OFF.

INSPECTION PROCEDURE
1. CHECK THE DTC
1. Clear the DTC using the Hi-Scan (pro).
2. Turn the ignition switch OFF.
3. Turn the ignition switch ON, and check if the same DTC is stored in the memory.

Is the same DTC output?

YES - Problem is intermittent and the HECU memory was not cleared.

NO - Check power source of valve relay

2. CHECK POWER SOURCE OF VALVE RELAY
1. Disconnect the connector from the HECU.




2. Measure the voltage between the terminals 25 and 8, 24 of the HECU connector.

Specification: Battery positive (B+)

Is the voltage within the specification?

NO
3. Check and replace fuse (10 A) and fusible link (30 A).
4. Check and repair harness or connector.

YES - Check circuit for continuity to ground.

3. CHECK CIRCUIT FOR CONTINUITY TO GROUND.
1. Disconnect the connector from the HECU.




2. Measure the resistance between terminals 8 (-), 24 (-) of the HECU connector and the body ground.

Is the resistance below 1 ohm?

YES - Check and readjust the installing of the body ground.

NO - Replace the HECU then recheck.
