DTC Fault Trigger Conditions

DTC

B119F:01

GPS Antenna: General Electrical Failure

Set by the APIM when a short to ground or short to battery voltage is detected on the GPS coaxial cable between the APIM and satellite radio/ GPS splitter for more than 250 milliseconds.

Continuous

B119F:13

GPS Antenna: Circuit Open

Set by the APIM when an open is detected on the GPS coaxial cable between the APIM and satellite radio/ GPS splitter for more than 250 milliseconds.

Continuous

B1A89:11

Satellite Antenna: Circuit Short To Ground

Set by the ACM when a short to ground is detected for more than 1 second on any of the following:

Satellite radio coaxial cable between the ACM and satellite radio/ GPS splitter Satellite radio/GPS splitter Rear satellite radio/GPS coaxial cable Antenna

Continuous and on-demand

B1A89:13 Satellite Antenna:

Circuit Open

Set by the ACM when an open is detected for more 250 milliseconds on any of the following:

Satellite radio coaxial cable between the ACM and satellite radio/ GPS splitter Satellite radio/GPS splitter Rear satellite radio/GPS coaxial cable Antenna

Continuous and on-demand

U1A00:87 Private

Communication Network: Missing Message

Set by the APIM when it sends a request over the HS-CAN3 to the ACM and does not receive a valid response from the ACM on the SDL circuits in five seconds with at least three retries, or if there is a fault which would prevent data from being transmitted through any of the following:

Satellite radio coaxial cable between the ACM and satellite radio/ GPS splitter Satellite radio/GPS splitter Rear satellite radio/GPS coaxial cable Antenna
