Detecting Condition
WARNING: This page is about a different car, the 2018 Kia Forte5 and 2018 Kia Forte. However, it is still accessible from the selected car via links, so may be relevant.
| Trouble Symptoms |
Possible Cause |
| Brake operation varies depending on driving conditions and road surface conditions, so diagnosis can be difficult. However if a normal DTC is displayed, check the following probable cause. When the problem is still occurring, replace the ESC control module. |
- Faulty power source circuit
- Faulty wheel speed sensor circuit
- Faulty hydraulic circuit for leakage
- Faulty HECU
|

Possible Cause |
| Brake operation varies depending on driving conditions and road surface conditions, so diagnosis can be difficult. However if a normal DTC is displayed, check the following probable cause. When the problem is still occurring, replace the ESC control module. |
- Faulty power source circuit
- Faulty wheel speed sensor circuit
- Faulty hydraulic circuit for leakage
- Faulty HECU
|
| Trouble Symptoms |
Possible Cause |
| Possible defect in the power supply system (including ground) for the diagnosis line. |
- An open in the wire
- Poor ground
- Faulty power source circuit
|
| Trouble Symptoms |
Possible Cause |
| When communication with GDS is not possible, the cause may be probably an open in the HECU power circuit or an open in the diagnosis output circuit. |
- An open in the wire
- Faulty HECU
- Faulty power source circuit
|
| Trouble Symptoms |
Possible Cause |
| When current flows in the HECU the ABS warning lamp turns from ON to OFF as the initial check. Therefore if the lamp does not light up, the cause may be an open in the lamp power supply circuit, a blown bulb, an open in the both circuits between the ABS warning lamp and the HECU, and the faulty HECU. |
- Faulty ABS warning lamp bulb
- Blown fuse is related to ABS in the engine compartment junction block
- Faulty ABS warning lamp module
- Faulty HECU
|
| Trouble Symptoms |
Possible Cause |
| If the HECU detects trouble, it lights the ABS warning lamp while at the same time prohibiting ABS control. At this time, the HECU records a DTC in memory. Even though the normal code is output, the ABS warning lamp remains ON, then the cause may be probably an open or short in the ABS warning lamp circuit. |
- An open in the wire
- Faulty instrument cluster assembly
- Faulty ABS warning lamp module
- Faulty HECU
