BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS BRAKE ACTUATOR(for Gasoline Model) RESET MEMORY / CALIBRATION
CAUTION / NOTICE / HINT
- NOTICE:
- ·
After replacing the skid control ECU (brake actuator assembly), perform "Calibration".
·As the yaw rate and acceleration sensor zero point cannot be stored again until the current zero point is cleared, perform "Reset Memory" and yaw rate and acceleration sensor zero point calibration and system information memorization after replacing or removing and installing the yaw rate and acceleration sensor (airbag sensor assembly*1 or airbag ECU assembly*2).
·While obtaining the zero point, keep the vehicle stationary and do not vibrate, tilt, move, or shake it.
·Be sure to perform this procedure on a level surface (with an inclination of less than 0.2°).
·While obtaining the zero point, make sure the tire pressure is as specified and the vehicle is in full contact with the ground (not lifted up or loaded).

- HINT:
- ·
Yaw rate and acceleration sensor zero point calibration and system information memorization are automatically performed immediately after Dealer Mode (Calibration) is entered.
·If system information memorization has not yet been performed, the slip indicator light will remain on and DTC C124A00 will be stored.
·If yaw rate and acceleration sensor zero point calibration is not successful, the slip indicator light will remain on and DTC C051D54 will be stored.
PROCEDURE
1. RESET MEMORY
Turn the ignition switch off.
Apply the parking brake.
Check that the shift lever is in P.
Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS on.
Select the skid control ECU (brake actuator assembly) to clear the zero point calibration data using the GTS. Enter the following menus: Chassis / Brake/EPB / Utility / Reset Memory.
- Chassis > Brake/EPB > Utility
-
Tester Display Reset Memory - 50005 435 4560
Using the GTS, perform "Reset Memory".
- NOTICE:
-
After perform "Reset Memory", the ABS warning light, brake system warning light (red indicator) and slip indicator light illuminate. If the vehicle is driven with the memory cleared, DTCs C124A00 and C051D54 will be stored.
2. CALIBRATION
Turn the ignition switch off.
Apply the parking brake.
Check that the shift lever is in P.
Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Check that the steering wheel is centered.
Turn the GTS on.
Switch the skid control ECU (brake actuator assembly) to calibration using the GTS. Enter the following menus: Chassis / Brake/EPB / Utility / Calibration.
- Chassis > Brake/EPB > Utility
-
Tester Display Calibration - 50005 435 4554
Using the GTS, perform "Calibration" and enter Dealer Mode (Calibration).
Confirm that the ABS warning light and slip indicator light indicate the Dealer Mode pattern (blinking at 0.25 seconds intervals).
- HINT:
- ·
After "Calibration" has successfully completed, the ABS warning light and slip indicator light indicate the Dealer Mode pattern (blinking at 0.25 seconds intervals).
·The slip indicator light may illuminate for approximately 7 seconds before learning successfully completes.
·When entering Dealer Mode (Calibration), if the parking brake is engaged, the parking brake indicator light (red) will illuminate, and if the parking brake is not engaged, the parking brake indicator light (red) will blink in the Dealer Mode pattern (blinking at 0.25 seconds intervals).
Turn the ignition switch off.
Disconnect the GTS.
