Rear Left Center Sensor Malfunction (C1AE7)
DESCRIPTION The No. 1 ultrasonic sensor (rear center sensor LH) is installed on the rear bumper. The ECU detects obstacles based on signals received from the No. 1 ultrasonic sensor (rear center sensor LH). If the No. 1 ultrasonic sensor (rear center sensor LH) has an open circuit or other ma ...

A-TRAC Indicator Light Remains ON
DESCRIPTION This is the A-TRAC main switch circuit. When the A-TRAC switch is turned on with the transfer in L4, the A-TRAC function is available and the A-TRAC indicator light illuminates. WIRING DIAGRAM CAUTION / NOTICE / HINT NOTICE: When replacing the skid control ECU (master ...

Vehicle Speed Signal Malfunction (B2282,B2283)
DESCRIPTION DTC B2282 is stored when the vehicle speed signal sent by the combination meter assembly via direct line and the vehicle speed signal sent via CAN communication do not match. DTC B2283 is stored when a malfunction in the vehicle speed sensor is detected. HINT: When the cable is d ...
