Toyota Corolla Cross: ABS Operation Continuous Request (C116E63,C116F63,C124E62)

Toyota Corolla Cross (2022-2024) Service Manual / Brake / Brake Control / Dynamic Control Systems / Electronically Controlled Brake System (for Gasoline Model) / ABS Operation Continuous Request (C116E63,C116F63,C124E62)

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.

DTC No.

Result

Proceed to

C116E63, C116F63 and/or C124E62 and C05001C, C05061C, C050C1C and/or C05121C are output simultaneously

A

C116E63, C116F63 and/or C124E62 is output

(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.
