SUBJECT:
Flash: RHW And RHP Navigation System Does Not Show The Proper Vehicle Location
OVERVIEW:
The Navigation system calculates distance traveled using the Antilock Brake System
(ABS) which requires an ABS software update.
MODELS:
2013
(RT)
Voyager/Grand Voyager/Town and Country
(international only)
NOTE: This bulletin applies to vehicles built before January 31, 2013 (MDH0131XX)
Build To Export MKT Specifications (sales code YAB) and equipped with
AM/FM/CD/NAV RADIO (sales code RHP) or Media Center 735N
CD/DVD/MP3/HDD/NAV (sales code RHW).
SYMPTOM/CONDITION:
The customer may experience the Navigation System was not accurate in tunnels,
mountains or where Satellite reception is likely to be poor.
At times the ABS controller is not properly calculating distance traveled. When Satellite
reception is poor, the Navigation system uses distance traveled to help calculate the
vehicles location.
DIAGNOSIS:
Using a Scan Tool (wiTECH™) with the appropriate Diagnostic Procedures available in
TechCONNECT, verify no Radio/Nav or ABS DTC's are set. If DTC's are present record
them on the repair order and repair as necessary before proceeding further with this
bulletin.
If the customer describes the symptom, perform the Repair Procedure.
