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) sends and receives signals at a radio frequency of between 824 and 894 MHz or 1850 and 1990 MHz through the telephone and GPS antenna.
DTC Code |
DTC Detection Condition |
Trouble Area |
---|---|---|
B1573 |
The telephone and GPS antenna impedance is lower than the malfunction criterion for 10 seconds when the ignition switch is ON. |
|
B15CB |
The telephone and GPS antenna impedance is lower than the malfunction criterion for 10 seconds when the ignition switch is ON. |
HINT:
Refer to "Parts Location" for the 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
).
