SCAN TOOL DOES NOT POWER UP
✓
Review the “ Safety Precautions” before troubleshooting.
If the tool will not power up, communicate with your vehicle’s PCM, pass Tool
Self-Tests, or functions incorrectly in any other way, then try these Trouble-
shooting Tips below before consulting Actron.
Though the tool requires at least 6.5V to power up, the vehicle’s control mod-
ules require a minimum of 8 volts to power up and operate.
Check the following:
Using Non-OBD II Adapter Cables
❒
The cigarette lighter adapter is hooked up. Make sure the cigarette
lighter end is firmly held in the cigarette lighter socket.
❒
Verify that the vehicle’s cigarette lighter fuse is OK. Some vehicles must
have the key on for the cigarette lighter socket to be on.
Using J1962 (OBD II) or Chrysler LH Adapter Cable
❒
Make sure the scan tool’s DLC is connected correctly to the vehicle’s
DLC. Verify the pins are clean and fully seated in the DLC.
❒
At least 8.0 volts (V) must be present between the power and ground
pins to power the computer module(s) and communicate.
