DTC C1776 SPEED SENSOR CIRCUIT

CIRCUIT DESCRIPTION

DTC Detecting Condition:

The speed sensor monitors the speed of a wheel, and sends an appropriate speed signal to the suspension control ECU through the brake actuator assembly (skid control ECU).

If trouble occurs in the either right rear speed sensor or left rear speed sensor, the DTC (C1776/76) is output. When inspecting by test mode, the suspension control ECU scans changes of the signals. If there is no change, it outputs the test DTC (C1784/84, C1785/85).

HINT: When DTC C1784/84 and C1785/85 are output, follow the same procedure as DTC 1776/76.
