Diagnosis System [08/2013 - 08/2016]

When troubleshooting a vehicle using the diagnosis system, the only difference from the usual troubleshooting procedure is connecting the Techstream to the vehicle and reading various data output from the skid control ECU (brake actuator assembly).

The skid control ECU (brake actuator assembly) records DTCs when it detects a malfunction in itself or in its circuits.

To check for DTCs, connect the Techstream to the DLC3 on the vehicle. The Techstream can be used to clear the DTCs, activate 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.

2. Check the DLC3.

   Refer to GENERAL INFORMATION [08/2013 - ]

1. If the skid control ECU (brake actuator assembly) detects a malfunction, the ABS warning, brake warning, and/or slip indicator lights will come on in order to warn the driver.
2. 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 and slip indicator lights, or by connecting the Techstream.

   Refer to DTC CHECK / CLEAR [08/2013 - 08/2015] Refer to DTC CHECK / CLEAR [08/2015 - ]

3. This system has a Test Mode (signal check) function.

   The DTCs can be read by connecting SST between terminals TS and CG of the DLC3 and observing the blinking pattern of the ABS warning and slip indicator lights, or by connecting the Techstream.

   Refer to TEST MODE PROCEDURE [08/2013 - 08/2015] Refer to TEST MODE PROCEDURE [08/2015 - 08/2016] 

1. Release the parking brake.
   NOTE:

   Before releasing the parking brake, move the shift lever to P (for continuously variable transaxle or automatic transaxle) or use wheel chocks to secure the vehicle (for manual transaxle).

   HINT: 

   When the parking brake is applied or the brake fluid level is low, the brake warning light comes on.

2. When the ignition switch is turned to ON, check that the ABS warning, brake warning, TRAC OFF indicator, VSC OFF indicator and slip indicator lights all 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, TRAC OFF indicator, VSC OFF indicator and slip indicator light circuits.
   • If any of the indicators remains on or does not come on, proceed to troubleshooting for the light circuits listed below.
