Circuit Description

WARNING: This page is about a different car, the 2005 Suzuki Swift +, 2005 Pontiac Wave, and 2005 Chevrolet Aveo. However, it is still accessible from the selected car via links, so may be relevant.

The data link connector (DLC) provides operating power for the scan tool at terminal 16. The ground for the scan tool is provided at terminal 4. The 16- pin DLC provides the serial data signals at terminals 7 (engine control module (ECM), transmission control module (TCM), immobilizer serial data), 8 (theft deterrent serial data), 12 (ABS serial data), and 13 (SIR serial data). The scan tool will power up with the ignition OFF. The ignition must be ON in order for the scan tool to communicate with a control module.
