Vehicle Stability Control System -- Diagnosis System



DESCRIPTION
When troubleshooting a vehicle with the diagnosis system, the only difference from the usual troubleshooting procedure is connecting the intelligent tester to the vehicle and reading various data output from the skid control ECU.
The skid control ECU records DTCs when the ECU detects a malfunction in the ECU itself or in its circuits.
To check the DTCs, connect the intelligent tester to the DLC3 on the vehicle. The intelligent tester enables you to erase the DTCs, activate the various actuators, and check the Freeze Frame Data and Data List.
  1. Check the battery voltage.

    Standard Voltage:
    11 to 14 V
    If the voltage is below 11 V, recharge the battery before proceeding to the next step.

  1. If the skid control ECU detects a malfunction, the ABS warning, brake warning, VSC OFF indicator, and slip indicator lights will come on in order to warn the driver.

  2. The DTCs are simultaneously stored in the memory.
    The DTCs can be read by connecting SST between terminals TC and CG of the DLC3 and observing the blinking pattern of the ABS warning and VSC OFF indicator lights, or by connecting the intelligent tester (Toyota Fortuner RM000000XHV09NX.html).

  3. This system has a Test Mode (signal check) function (Toyota Fortuner RM000000XHT070X.html).


WARNING LIGHT AND INDICATOR LIGHT INITIAL CHECK
  1. Release the parking brake.

    NOTICE:
    When releasing the parking brake, move the shift lever to the P position for safety.
    HINT:
    When the parking brake is applied or the level of the brake fluid is low, the brake warning light comes on.
  2. When the ignition switch is turned to ON, check that the ABS warning, brake warning, VSC OFF indicator, and slip indicator lights come on for approximately 3 seconds.

    HINT:
    If the warning light and indicator light check result is not normal, proceed to troubleshooting for the ABS warning, brake warning, VSC OFF indicator, or slip indicator light circuits.
    If the indicator remains on or does not come on, proceed to troubleshooting for the light circuits listed below.
