DTC | |||||
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 | On-demand | ||

Ignition ON. Access Bezel Diagnostics. REFER to: Bezel Diagnostics (415-00B Information and Entertainment System - General Information - Vehicles With: Touchscreen Display, General Procedures). Monitor the "Number of Satellites" and "Fix Mode" in APIM Location Information. If the values read less than 3 for "Number of Satellites" or "No GPS Fix" for "Fix Mode," drive the vehicle to an outdoor location that is free from obstacles such as tall buildings or large trees until at least 3 satellites are listed for "Number of Satellites" and "3D" is listed for "Fix Mode."
Can 3 or more satellites and a 3D fix be obtained?
