K73 Telematics Communication Interface Control Module: Programming and Setup: Notes

CAUTION:

Before programming a control module, the following must be observed, or control module damage may occur:

The TIS terminal, MDI, and/or scan tool must have the latest software.
The vehicle battery must be fully charged. The battery voltage should be between 12 - 14 volts.
The TIS terminal, MDI, and/or scan tool connections must be secure.
A battery charger must NOT be connected to the battery when programming a control module.

NOTE:

Do NOT program a control module unless directed to by a service procedure or a service bulletin. If the control module is not properly configured with the correct calibration software, the control module will not control all of the vehicle features properly.
Stable battery voltage is critical during programming. Any fluctuation, spiking, over voltage or loss of voltage will interrupt programming. When required install the below mentioned special tool to maintain system voltage. If not available, connect a fully charged 12 V jumper or booster pack disconnected from the AC voltage supply.
Turn Off or disable systems that may put a load on the vehicle's battery. For example, interior lights, daytime running lights, HVAC, and radio.
During the programming procedure, follow the Service Programming System (SPS) prompts for the correct ignition switch position.
Clear DTCs after programming is complete. Clearing powertrain DTCs will set the Inspection/Maintenance (I/M) system status indicators to No.
