DESCRIPTION

This DTC is stored when a failure of the automatic light control sensor circuit is detected.

Scheme 150

This DTC is stored when the main body ECU detects malfunctions in the inner rear view mirror.

Scheme 151

This DTC is stored when the main body ECU detects malfunctions in the automatic high beam system.

1. DTC B124D is stored when the main body ECU detects malfunctions in the LIN communication system.
2. DTC B2432 is stored when the AFS ECU detects malfunctions in the LIN communication system.

Scheme 152

This DTC is stored when the main body ECU detects malfunctions in the turn signal flasher relay circuit.

Scheme 153

These DTCs are stored when the AFS ECU detects errors in its own communications with the headlight swivel motor.

Scheme 154

The headlight swivel motor receives a signal from the AFS ECU to operate and sends a signal indicating the direction of the headlight and condition of the headlight swivel motor to the AFS ECU.

Scheme 155

The AFS ECU receives signals indicating the steering angle from the steering angle sensor using CAN communication.

Scheme 156

The AFS ECU receives signals indicating the front wheel speed from the skid control ECU using CAN communication.

Scheme 157

The AFS ECU receives signals indicating the height of the vehicle from the suspension control ECU.

Scheme 158

The headlight swivel motor (leveling portion) receives a signal from the AFS ECU to operate. The AFS ECU receives a signal indicating the operating conditions of the headlight swivel motor (leveling portion).

Scheme 159

When the AFS ECU detects a malfunction in itself, this DTC is stored.

This DTC is stored if the AFS ECU is not installed properly.

The headlight swivel motor (leveling portion) operates by receiving a signal from the AFS ECU. The AFS ECU detects the headlight swivel motor (leveling portion) status using the signal from the headlight swivel motor (leveling portion).

Scheme 160

1. The AFS ECU receives an engine running status signal and shift position signal from the ECM using CAN communication.

1. The AFS ECU receives front speed sensor LH and RH signals from the skid control ECU using CAN communication.

1. The AFS ECU receives the headlight status signal from the main body ECU using CAN communication.

1. The AFS ECU sends an AFS OFF indicator light on or off demand signal to the combination meter ECU using CAN communication.

The AFS ECU receives steering wheel position information (turned to the right or left) from the main body ECU via CAN communication.

Scheme 161

The main body ECU receives a headlight switch information signal from the light control switch, and illuminates the headlight low beam.

Scheme 162

The main body ECU receives light control switch and dimmer switch information signals from the headlight dimmer switch, and illuminates the headlight high beam.

Scheme 163

Scheme 164

The main body ECU receives a front fog light switch information signal from the light control switch (front fog switch), and illuminates the front fog lights.

Scheme 165

The park/neutral position switch turns on when the shift lever is moved to R, causing the back-up lights to illuminate.

Scheme 166

When the stop light switch is turned on, current flows to the stop lights to illuminate them.
