  1. DIAGNOSIS

Anti-Lock Brake 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 vehicle's skid control ECU (brake actuator assembly).
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 clear 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 diagnosis.

  2. Check the DLC3 (HILUX_TGN26 RM000004QR5001X.html).


DIAGNOSIS

  1. If the skid control ECU (brake actuator assembly) detects a malfunction, the ABS warning light will come on to warn the driver.
    The DTCs are simultaneously stored in 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 light, or by connecting the intelligent tester (HILUX_TGN26 RM000000XHV0CFX.html).
    This system has a Test Mode (signal check) function (HILUX_TGN26 RM000000XHT090X.html).
