HELP USING THE wiTECH DIAGNOSTIC APPLICATION FOR FLASHING AN ECU IS
AVAILABLE BY SELECTING “HELP” THEN “HELP CONTENTS” AT THE TOP OF
THE wiTECH DIAGNOSTIC APPLICATION WINDOW.
THE wiTECH SOFTWARE LEVEL MUST BE AT RELEASE 13.03 OR HIGHER TO
PERFORM THIS PROCEDURE.
SUBJECT:
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 and if required radio replacement.
MODELS:
2012

(RT)

Voyager/Grand Voyager/Town and Country
(international only)

NOTE: This bulletin applies to international vehicles, 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 when using the Navigation system, it shows their vehicle in
the wrong location.
This is caused by the GPS system locking in on 3 or less satellites, which is due to
Electromagnetic Interference (EMI) blocking the satellite signals. Also the Navigation
system is not getting the proper distance traveled from the ABS module.
The system needs to have a lock on 4 or more satellites, to function properly. Replacing
the radio will correct this condition. The Navigation system needs proper distance traveled
to calculate vehicle location when the satellite signals are blocked by mountains or large
buildings. Updating the ABS module will correct this conditions.
DIAGNOSIS:
Using a Scan Tool (wiTECH™) with the appropriate Diagnostic Procedures available in
TechCONNECT, verify no Radio/Nav are set. If DTC's are present record them on the

REPAIR PROCEDURE:
1. Using the wiTECH check if the ABS module has the latest software.
2. Is the ABS module programmed with the latest software?
a. Yes >>> Proceed to Step #5.
b. No >>> Update the ABS module software, proceed to Step #3.
NOTE: Install a battery charger to ensure battery voltage does not drop below 13.2
volts. Do not allow the charging voltage to climb above 13.5 volts during the
flash process.
NOTE: If this flash process is interrupted/aborted, the flash should be restarted.
3. Flash reprogram the ABS module. Help using the wiTECH Diagnostic Application for
flashing the control modules is made available through the wiTECH Diagnostic
Application. For instructions select the “HELP” tab on upper portion of the wiTECH
window, then “HELP CONTENTS”. This will open the Welcome to wiTECH Help
screen where help topics can be selected.
4. Clear any DTC's that may have been set in other modules due to reprogramming. The
wiTECH application will automatically present all DTCs after the flash and allow the
tech to clear them.
NOTE: A customer may experience a similar type concern under normal conditions.
Satellite signals can be block by mountains, large building and location. This
condition will be easy to duplicate, if the radio has this issue. Before
performing this bulletin the condition HAS to be duplicated.
5. Can you duplicate the condition?
a. Yes >>> Check the number of satellites the radio can lock on, proceed to Step #6.
b. No >>> This bulletin doesn't pertain, normal diagnostics needs to be performed.
6. Take the vehicle to a open area clear of any obstruction that can block the satellite
signals.
7. Press the Menu hard key on the outside of the radio.
8. Press soft key NAV Setting, then GPS Information soft key.
9. The number of satellites will be displayed in the lower right hand corner of the screen.
