Fault Diagnosis

  1. In principle, ESP and TCS control is prohibited when an ABS failure occurs.
  2. If an ESP or TCS failure occurs, only the malfunctioning system control is prohibited.
  3. However, when the solenoid valve relay must be turned off in the event of an ESP failure, refer to ABS fail-safe.
  4. ABS fail-safe information is identical to the fail-safe for systems where ESP is not installed.
  5. It stores the code as long as backup lamp power is connected. (O)
  6. It stores the code as long as HCU power is on. (X)
  7. The initial check is performed immediately after the HECU is powered on.
  8. The valve relay check is performed immediately after IG2 is turned on.
  9. It performs the check at all times while IG2 power is on.
  10. The initial check is performed in the following cases.
    1. When no fault is detected.
    2. When ABS and ESP are not monitored.
    3. The initial check is not performed after the ECU is powered on.
    4. If vehicle speed exceeds 8 km/h when the stop lamp switch is OFF.
    5. When the vehicle speed exceeds 24.8 mph (40 km/h).
  11. However, the check continues even when the stop lamp switch is on.
  12. When performing ABS or ESP control before the initial check, stop the initial check and wait again for HECU power input.
  13. The judgment fails in the following cases.
    1. When the power supply is normal.
    2. From the moment the vehicle speed reaches 4.9 mph (8 km/h) after the HECU is turned on.
  14. Turn the system off, perform the following steps, and wait until the HECU is turned off.
  15. Turn off the valve relay.
  16. Do not perform any ABS/TCS/ESP functions until normal operating condition is restored.
  17. The ABS warning lamp illuminates when an ABS malfunction occurs.
  18. The ESP function/warning lamp illuminates when an ESP malfunction occurs.
Diagnostic Trouble Code Memory Inspection Fail-Safe Warning Lamp ON When the supply voltage and the valve relay voltage are out of specification, the input/output is not judged for malfunction.
