Pinpoint Test P: The Position Cursor Is Inaccurate
Normal Operation
The primary source of vehicle location for the navigation system is the Audio Control Module (ACM) receiving the position signal through the Global Positioning System (GPS) antenna (integral to the satellite radio antenna).
In addition, the ACM receives the navigation rolling wheel count signal from the Instrument Cluster (IC) (which gateways the signal from the ABS module). This secondary signal is used to calculate vehicle position when the GPS signal is lost. It also supports the adaptive learning function of the ACM, whereby the ACM can compensate for long-term differences between the GPS signal location and the actual distance traveled by the vehicle.
If DTC B119F:01 or B119F:13 is present, Go To Pinpoint Test O to diagnose a concern with the GPS antenna. Pinpoint Test O: No Global Positioning System (GPS) Antenna Signal
- DTC U2014:09 (Control Module Hardware: Component Failure) - sets when the ACM detects a fault in the internal gyroscope. The gyroscope is not serviceable.
This pinpoint test is intended to diagnose the following:
- GPS antenna concern
- Communication network concern
- ACM
