DESCRIPTION
This DTC is stored when the DCM (Telematics Transceiver) detects an open or a short in the telephone and GPS antenna circuit. The DCM (Telematics Transceiver) receives signals at a radio frequency of between 1574.42 and 1576.42 MHz through the telephone and GPS antenna. The cable is a 50 Ω coaxial cable.
DTC Code |
DTC Detection Condition |
Trouble Area |
---|---|---|
B15C0 |
Current for the telephone and GPS antenna is more than the malfunction criterion for 10 seconds when the ignition switch is ON. |
|
B15C1 |
Current for the telephone and GPS antenna is less than the malfunction criterion for 10 seconds when the ignition switch is ON. |
HINT:
Refer to "Parts Location" for installation location of the telephone and GPS antenna cord (See page ).
PROCEDURE
1. |
CHECK FOR DTC |
(a) Turn the ignition switch off.
(b) Connect the Techstream to the DLC3.
(c) Turn the ignition switch to ON and wait for 10 seconds.
(d) Perform "Health Check" and check for current DTCs (See page ).
