USB Audio System Recognition/Play Error
DESCRIPTION
When a USB device or "iPod" is connected to the USB jack of the No. 1 stereo
jack adapter assembly, it must have playable files. The device must also communicate
with and be recognized by the radio and display receiver assembly. This diagnosis

Invalid Data Received from Deceleration Sensor (C1442,C1443)
DESCRIPTION
The airbag sensor assembly has a built-in yaw rate and acceleration sensor.
The skid control ECU (brake actuator assembly) receives signals from the yaw
rate and acceleration sensor (airbag sensor assembly) via the CAN communication
system.
DTC No.
