This DTC is output when a communication malfunction occurs between the sensors and ECUs.

This DTC indicates internal abnormalities of the ECM.

The distance control ECU sends brake control request signals, warning request signals, etc. to the master cylinder solenoid (skid control ECU) through the ECM. Based on these signals, the brake actuator operates and the warning buzzer sounds. The master cylinder solenoid (skid control ECU) sends brake system malfunction signals, etc. to the ECM.

Remove the STOP and IGN fuses from the engine room relay block.

The distance control ECU sends brake control request signals, warning request signals, etc. to the master cylinder solenoid (skid control ECU) through the ECM. Based on these signals, the brake actuator operates and the warning buzzer sounds. The master cylinder solenoid (skid control ECU) sends brake system malfunction signals, etc. to the ECM.

If a malfunction (a rapid change in vehicle speed) in the vehicle speed signal being output from the master cylinder solenoid (skid control ECU) is detected while the dynamic radar cruise control is in operation, the ECM determines there to be a momentary interruption and noise, and outputs a DTC.

In the dynamic radar cruise control system, the ECM and the distance control ECU communicate with one another to control the system based on designation information. If the designation information of the ECM and the distance control ECU is different or the distance control ECU is malfunctioning, this DTC is recorded.

The speed sensor detects the wheel speed and sends the appropriate signals to the master cylinder solenoid (skid control ECU). The master cylinder solenoid (skid control ECU) converts these wheel speed signals into a 4-pulse signal and outputs it to the ECM via the combination meter. The ECM determines the vehicle speed based on the frequency of these pulse signals.
