DTC |
B15C0 |
Short in GPS Antenna |
|
DTC |
B15C1 |
Open in GPS Antenna |
DESCRIPTION
This DTC is set when the DCM (Telematics Transceiver) detects an open or a short in the telephone and GPS antenna circuit. The DCM (Telematics Transceiver) receives 1574.42 - 1576.42 MHz radio frequency signals from satellites through the telephone and GPS antenna assembly. The cable is a 50 Ω coaxial cable.
|
DTC No. |
DTC Detection Condition |
Trouble Area |
|---|---|---|
|
B15C0 |
Current for telephone and GPS antenna assembly is lower (Ω) malfunction criterion for 10 seconds when ignition switch is ON. (Short circuit) |
|
|
B15C1 |
Current for telephone and GPS antenna assembly is higher (Ω) malfunction criterion for 10 seconds when ignition switch is ON. (Open circuit) |
HINT:
Refer to "PARTS LOCATION" for the installation location of telephone and GPS antenna cord (See page
![2016 - 2017 MY Sienna [12/2015 - 11/2017]; CELLULAR COMMUNICATION: SAFETY CONNECT SYSTEM: PARTS LOCATION](/t3Portal/stylegraphics/info.gif)
).
PROCEDURE
|
1. |
CHECK 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) Turn the Techstream on.
(e) Perform "HEALTH CHECK" and check for current DTCs (See page
).
