INFORMATION
Subject:
IPC Odometer Programming Method Quick Reference Guide
Models:
2020 and Prior GM Passenger Cars and Trucks
Attention: This bulletin applies to vehicles sold in the U.S. and Canada Only.
This bulletin has been revised to add the 2020 Model Year, update the information in the table
and remove the Chevrolet
Low Cab Forward models. Please discard Corporate Bulletin
Number 07-08-49-020P.
The purpose of this bulletin is to provide a reference
guide to help identify which season odometer
programming method to use after replacing the
instrument panel cluster (IPC). The three season
odometer programming methods in use today are listed
below. In addition, this reference guide lists the
component where the season odometer value is stored.
The season odometer value may be stored in the IPC,
the driver information center (DIC) or the integrated
body control module (IBCM), also commonly called a
body control module (BCM).
Season Odometer Programming Methods in Use
Today
1. IPC reprogramming and setup using the service
programming system (SPS).
Model
2. Odometer setup at the electronic service center
(ESC) when using an exchange IPC/DIC.
3. Tech 2® – The Tech 2 is used to set up a
replacement BCM, which includes loading the
odometer value that is displayed and stored in the
IPC. A replacement IPC will display the previously
stored vehicle odometer value, communicated
from the BCM, after cycling the ignition or driving
the vehicle.
Important: Stable battery voltage is critical during
programming. Any fluctuation, spiking, over voltage or
loss of voltage will interrupt programming. Install the
EL-49642 SPS Programming Support Tool (GM Dealer
Equipment Item #PSC-550) to maintain system voltage.
If not available, connect a fully charged 12V jumper or
booster pack disconnected from the AC voltage supply.
DO NOT connect a battery charger.
