No power when i plug in a code scanner - 2006 Buick Rainier

The scanner check procedure for Innova or Innova venturer is as follows:
(1) Turn the ignition switch to OFF (disconnected);
(2) Plug the scanner power cord into the cigarette lighter holder;
(3) Connect the scanner to the diagnostic communication circuit or the diagnostic socket of the check connector;
(4) Turn on the ignition switch; start the scanner to check the fault code;
(5) Turn off the ignition switch for troubleshooting and analysis, then turn on the ignition switch, and use the scanner to erase the stored fault code;
(6) Take off the scanner.

Check for power at d.l.c.if none find blown fuse in c.j.b

remove the ecu plug connection and check these connections, you will need the wiring code and check the wires from the ecu plug to the obd scan socket. if this is all fine check the scanner on another vehicle and check it works on that one if the same fault then the scanner is the problem, could be one of the miro switchers in the scanner have gone.

This is on a 1987 audi 5000s. The light that comes on is an engine with a lightning bolt through it. When this comes on the car loses power, have to turn off and restart. That will work for a short distance and the light back on again. I just got the car about a month ago for my 16 yr. son's first car. If there is anything you can do I appreciate it. Thank you.
Open the driver's door of the PT Cruiser and kneel down to locate the 16-point data link connector (DLC) under the dash. It sits up under the dash to the left of the brake pedal on earlier model Cruisers. Later models moved the connector slightly to the right, closer to the steering wheel column, but still under the dash.

2 Plug the pocket scanner plug into the DLC. Because of its unique shape, there is only one way to plug any connectors onto the DLC, making it foolproof.

3 Place the key into the ignition and turn it two clicks forward to the "II" position. This position provides accessory power and illuminates the instrument cluster without the engine running. It also provides accessory power to the pocket scanner.

4 Read the onscreen menu of the pocket scanner. The scanners are easy to use, but if necessary, read the manual provided with the scanner to navigate through the menu. Many modern pocket scanners are equipped with "Erase" buttons -- in that case, press erase to reset the code. Other models may have "Enter" or "Scroll" button(s) to navigate through a few different options (one of the options being the erase codes option).

5 Erase the code(s) with the scanner and start the engine of the Cruiser. Determine if the service light is out. If not, repeat the procedure. If the light is still on, it means there is a "hard code" that must be read (with the scanner under "Read Codes" option) and properly repaired.

is your code reader "can" ready? the newer cars communicate to scanners using different protocols and your scanner may not have that protocol. have you scanned the vehicle using this scanner before? also check fuses as most manufacturers use the cigaret lighter fuse to power the "dlc" data link connector.

What kind of problems are you having? You plug it in, turn key to "ON" not start and scanner goes into scan mode. You can then scroll up & down between options. (I have one also)

the engine has to be off abd the key in the on position.

Not exactly. The scanner doesn't get its power from the computer of the car, but from another pin, which is the 16. You may have some blown fuses to the computer, which could be the same fuse for the pin 16 which is the power for the scanner. You can check on the Data Link Connector pin 16 if you have 12v, if you don't start looking for blown fuses.

you need to have the code read to see what it is most auto parts store can do that for free that will help use tell you what it is

you most likley have a blown fuse. the fuse for the connector and cig lighter are usually on the same circuit . if you have a owner manuel check and see which fuse is for the obd/cig lighter. if you dont have a manuel then check every fuse in the box and see if you find a blown one. the plug whare the scanner connects is what powers the scanner so if you cant find a blown fuse then you know youre not getting power to the plug for some reason.
