Possible Error Messages

CALIB. = "ERROR" means a malfunction occurred during calibration
SENSOR = "GPS" means there is a reception problem or there is no communication with the GPS module. "GAL" means there is a malfunction in the speed-dependent volume control (GALA). "R" means reverse light signal was not recognized
INTERNAL = "ERROR" means there are malfunctions in the gyrocompass or GPS receiver
CD-DRIVE = "CD" means malfunctions occurred when reading the CD. "TEMP" means the temperature in the CD drive is too high

NOTE:

A malfunction is only display if it is active at the time of the malfunction check and the internal malfunction counter has exceeded a certain number for frequency of this malfunction.
