TELEMATICS TELEMATICS SYSTEM(for Gasoline Model) B15CB11 Telephone Main Antenna Circuit Short to Ground B15CB13 Telephone Main Antenna Circuit Open

DESCRIPTION

If an open or short circuit in the navigation antenna assembly is detected continuously for 1 minute as a result of a terminal check performed by the telematics transceiver every minute after the engine switch is turned on (IG), these DTCs will be stored.

DTC No.	Detection Item	DTC Detection Condition	Trouble Area
B15CB11	Telephone Main Antenna Circuit Short to Ground	Navigation antenna assembly impedance (Ω) is lower than the malfunction threshold for 10 seconds or more when the engine switch is on (IG) (Short circuit)	· Navigation antenna assembly · Antenna cord sub-assembly · Telematics transceiver
B15CB13	Telephone Main Antenna Circuit Open	Navigation antenna assembly impedance (Ω) is higher than the malfunction threshold for 10 seconds or more when the engine switch is on (IG) (Open circuit)	· Navigation antenna assembly · Antenna cord sub-assembly · Telematics transceiver
