DESCRIPTION
The skid control ECU (brake actuator assembly) measures the speed of each wheel by receiving signals from each speed sensor.
These signals are used for recognizing that all four wheels are operating properly.
Therefore, signals from all wheels must be equal.

PROCEDURE
1. |
CHECK DTC |
(a) Read the DTCs using the GTS.
Chassis > Brake/EPB > Trouble CodesHINT:
When DTC C05001C, C05061C, C050C1C and/or C05121C are output together with DTC C116E63, C116F63 and/or C124E62, inspect and repair the trouble areas indicated by DTC C05001C, C05061C, C050C1C and/or C05121C first.

2. |
PRE-CHECK |
(a) Check that all 4 tires are of correct size, are inflated to the correct pressure, and do not show excessive signs of wear.

HINT:
If a tire is deformed or an incorrectly sized tire or wheel is installed, this DTC may be stored.

3. |
CHECK FREEZE FRAME DATA (WHEEL SPEED AND VEHICLE SPEED) |
(a) Select a DTC to display the Freeze Frame Data.
(b) Read the freeze frame data of DTC C116E63, C116F63 and/or C124E62.

(b) Start the engine.
(c) Perform a road test under the same malfunction conditions recreated based on the Freeze Frame Data or customer problem analysis.
(d) Check the value of Wheel Speed and Vehicle Speed.
OK:
The value of each Wheel Speed and Vehicle Speed changes in accordance with vehicle speed and the maximum difference between any 2 sensors is less than 6%.
HINT:
If the result of the road test is within the specified range, it is possible that this DTC was stored due to a particular situation.
Using to the freeze frame data, the approximate vehicle conditions that were present when the DTC was stored can be determined.
