Onstar Component Replacement - 9-5 Wagon

VIU/VCU

To remove:

1 Lift the cover off of the passenger side storage bin in the cargo area.





2 Remove the storage bin containing the VIU/VCU modules out by lifting the front extension first.

3 Release the electrical connectors from the modules.





4 To remove the VCU, release the retaining strap.

5 To remove the VIU, remove the 4 screws securing the metal bracket to the underside of the plastic bin.

To fit:

1 Refit the new module(s) in reverse order. Take care when refitting the storage bin that it is fitted with the rearward extension first. Take up the slack in the wiring harness and tuck it behind the carpet.

NOTE:
Before fitting the new module(s), the serial number (VCU) or station ID (VIU) must be recorded and provided to the OnStar Call Center, at 1-888-ONSTAR1, prompt 1.

2 Reset the Onstar system by pressing and holding the Call End (white dot) button on the OnStar three-button assembly. The LED will be green, turn red, then go back to green again.

3 Move the vehicle outside. Leave it running for ten minutes. Press the OnStar key and ask the advisor for a reconfiguration.

If you have trouble connecting to OnStar, configuring or activation on a Saab OnStar system, try the following:

^ Let the car run for 10 minutes. then press the blue OnStar Call Button. You should see the LED flashing green because a call is in progress You will then hear connecting to OnStar. You may also hear a fast busy beep then dead air, and then a cell carrier message. The important thing is to allow enough time for the call to go through: at least 5 minutes. If OnStar requested ended is heard, then try the red emergency key next. Always write down what you hear after the keypress for the OnStar Technical Assistance Center consultant: this will help in diagnosis.

^ Check to make sure the coax cable is connected to the VCU and coupling box. Also make sure the coax cable is not nicked, cut, scraped or twisted above the headliner.

^ Next check the cell antenna installation. Make sure the cell antenna is mounted in the correction location, the antenna is above the vehicle roof line, the coupling box and cell antenna mount are lined up properly, and finally, there is not after-market window tint on the vehicle glass.
