Using Output Controls With A Scan Tool

IMPORTANT: Do not use the scan tool Output Controls until the vehicle is at normal operating temperatures. The PCM will not respond to a request for Output Controls until the engine coolant temperature is above 80°C (175°F). Failure to wait for normal operating temperatures can result in the incorrect diagnosis of a driveability problem.

The Output Controls are disabled if the PCM stores any DTCs. Clear the DTCs before using the scan tool Output Controls.

The Tech 2 can command the PCM to operate solenoids, valves, motors, and switches. This scan tool function is referred to as the "Output Controls". The Output Controls item is in the Special Functions menu on the Tech 2 scan tool. Limit the operation of a PCM controlled device with the scan tool to a maximum of 10 seconds per test period.
