Lexus ES: ABS Solenoid Control Module Actuator Stuck On (C143A7E,C143A7F,C143D49,C14DA14)
DESCRIPTION
The ABS solenoid relay is built into the skid control ECU in the brake actuator assembly. The ABS solenoid relay supplies power to each solenoid.
The skid control ECU (brake actuator assembly) detects an ABS solenoid relay malfunction by performing a self check and relay operation check.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| C143A7E | ABS Solenoid Control Module Actuator Stuck On | When an ABS solenoid relay OFF request is sent, the ABS solenoid relay remains ON for 0.065 seconds or more. | Skid control ECU (brake actuator assembly) |
| C143A7F | ABS Solenoid Control Module Actuator Stuck Off | When an ABS solenoid relay ON request is sent, the ABS solenoid relay remains OFF for 0.015 seconds or more. | Skid control ECU (brake actuator assembly) |
| C143D49 | ABS Solenoid Control Module Internal Electronic Failure | A malfunction in the ABS solenoid relay drive circuit is detected during the self test. | Skid control ECU (brake actuator assembly) |
| C14DA14 | ABS Solenoid Supply Voltage Circuit Short to Ground or Open | The ABS solenoid voltage is less than 40% of the +BS voltage for 0.185 seconds or more. | Skid control ECU (brake actuator assembly) |
CAUTION / NOTICE / HINT
NOTICE:
After replacing the skid control ECU (brake actuator assembly), perform acceleration sensor zero point calibration and store system information memorization.
