logic card have to change

Bad main board. Get the number off the board as there are 2 different kinds.

Sounds like your controller board is bad but would need some more information from you. Like controller board part# with version #. email or contact me back. rcardenas@mrp.to

This is a 15V power failure, but refers usually to the ribbon drive.
Here's a PDF with these things explained and the areas of the circuit board involved.

You won't find a better document for this failure than this one, but look it over thoroughly.

chek your printer smps or connection loos contact

Only way you can get 15v anywhere is if the voltage regulator in the charging system has failed or your meter is inaccurate. Check meter against another known good one and if good, go for the regulator (can be in the computer or alternator depending upon which system is in yours) Nothing in the system should ever have more than normal battery voltage...12-14max.

Sometimes the plastic cog on the side of the throttle body (TB) breaks. This cog is "pulled" by the cruise control accuator's cable.
To check, simply look on the side of the TB and check to see of the cable end has broken free. (The mechanisim is much like the brake cable on a bike)

Hi Serap,

If a fault condition occurs in the printer, the status indicator on the control panel flashes on and off, and the message display indicates the specific fault.

For the operator-correctable faults, After correcting the displayed fault, press the CLEAR key to clear the error message and status indicator and resume printing. If the fault message reappears, contact your authorized service representative.
If a fault is not correctable by the operator, you may try two steps to clear the fault before calling your authorized service representative:

1. Set the printer power switch to O (Off), wait 15 seconds, then turn the printer on again. Run your print job again. If the message does not appear, it was a false indication and no further attention is required.

2. If the message reappears, press the CLEAR key. If the message disappears, it was a false indication and no further attention is required. If the message reappears, call your authorized service representative at 1-800-243-3338.

As far as software for the flash file is concerned , I have checked with their officaial sites , but they donot have any firmware updates.
