C1776

DTC C1776/76 Speed Sensor Circuit

DESCRIPTION

DTC Detection Condition:

The speed sensors monitor the speed of the front wheels, and send appropriate speed signals to the stabilizer control ECU through the skid control ECU.

If trouble occurs either in the right front or left front speed sensor, the DTC (C1776/76) is output.

When inspecting in test mode, the stabilizer control ECU scans changes of the signals. If there is no change, the ECU outputs the test DTC (C1794/94, C1795/95).
