Toyota Tacoma 2015-2018 Service Manual / Brake Control / Dynamic Control Systems / Vehicle Stability Control System(for Vacuum Brake Booster) / Unusual Bank Angle Detected (C1440)

DESCRIPTION

If the skid control ECU (brake actuator assembly) determines that the vehicle is being driven at a steep bank angle, the skid control ECU (brake actuator assembly) stores DTC C1440 while VSC operation is temporarily disabled.

This is not a malfunction if the system and sensor circuits are normal and normal VSC operation resumes.

HINT:

If the skid control ECU (brake actuator assembly) determines that the vehicle is being driven at a steep bank angle, the skid control ECU (brake actuator assembly) stores DTC C1440 while VSC operation is temporarily disabled.
It is not a malfunction if the system and sensor circuits are normal and if the normal VSC operation resumes, which automatically clears DTC C1440, after the vehicle is returned to a normal position.
