Powertrain Interface Module – V6 

Page 6E1–6 

 

1 General 

Information 

A powertrain interface module (PIM) is fitted that incorporates the following functionality: 

• 

Communication protocol between the engine control module (ECM) and transmission control module (TCM) is 
General Motors Local Area Network (GM LAN). 

• 

Communication protocol between the PIM and immobiliser control unit is keyword 2000. 

• 

ECM to PIM and PIM to immobiliser control unit (ICU) authentication for vehicle security. 

• 

The following switches, where fitted, input directly into the PIM: 

• 

Automatic transmission power mode switch. 

• 

Automatic transmission 3

rd

 gear start switch. 

• 

Cruise control switch. 

1.1 General 

Description 

Serial Data Communication 

The various electronic control modules communicate with each other through the serial data bus. The ECM and TCM 
communicate on the serial data bus using the GM LAN communication protocol. Figure 6E1 – 2 shows the serial data 
layout. 

N O T E  

Serial data components shown in Figure 6E1 – 2 
will vary depending on vehicle options. 

Bus 

A bus is a physical circuit or circuits which provides a communication path between two or more control modules.  

GM LAN Serial Data Bus 

The GM LAN bus is a two wire circuit (1), refer to Figure 6E1 – 1. The GM LAN bus circuits are terminated with cut-off 
resistors (2) which are located inside the two control modules at either end of the bus circuit. The purpose of these cut-off 
resistors is to prevent data from returning as an echo after reaching the end of the GM LAN bus circuit. 

N O T E  

•  For illustration purposes, the cut-off resistors 

are shown outside of the control modules. 

•  The two control modules with the cut-off 

resistors are the PIM and the ECM.
