Title: BRAKE CONTROL: VEHICLE STABILITY CONTROL SYSTEM: C1336/39; Zero Point Calibration of

Acceleration Sensor Undone; 2015 MY Tundra [08/2014 - ]

DTC

A new skid control ECU is supplied without zero point calibration for the deceleration sensor and master cylinder

pressure sensor. Until the zero points are calibrated, DTC C1336/39 remains stored. By entering test mode, the

zero point calibration is automatically performed, and DTC C1336/39 is erased automatically.
