"Linking Error" OBDII Comm failure ' DSMtuners

Hey...this code sets after maintaing the throttle body...this error is ABS speed sensor related...its an acceleration or deceleration error code...to clear this code... U need a profesdsional scanner to relearn the sensors...its a process called G-zero initialization...!
Am your Digimaster!

You have a fault with ASC you need to get the fault code.

Hi James,

With the key in the ignition you cycle the key to the on position ( not start) 3 times and stop on the 4 th on position. it will appear in the odometer screen. It make take a few tries to get it. Cheers!

This is the ASC indicator. It comes on when the system is turned off. To get the light out, turn the system back on by pushing the ASC(dsc) button on the console. It's located just ahead of the shift lever. ASC is the Automatic Stability Control system.
It's a traction control light. it warns whenever the system is turned on and the car senses a loss of traction. you can deactivate the system by pushing the ASD(dsc) button and holding. this light will illuminate to say: you may lose traction.
Can sometimes be activated by faulty brake(ABS) sensors,ABS pump,While checking ensure that your brake pads aren't worn right down.
If the light still stays up get your local service dealer to scan cars computer for fault code relating to which sensor is perhaps faulty.
I hope this helps you or get back with your findings

take it for a diagnostic check up to display and read out codes and errors.

If you have an automatic transmission, you may have two exclamation points in warning lights on the dash. The one in the circle with gear cogs around its perimeter is an error warning light for the computer in the automatic transmission. I have never had that light, but I would first disconnect the battery to try to clear it, and if that failed, I would have to take the car to a good independent shop that specializes in BMWs. Go to Car Talk website for recommendations for a shop.
The exclamation point in a triangle which in turn is in a circle, located between the speedometer and tach, is for the Automatic Stability Control. It should illuminate when you press the ASC button on the console which turns the ASC off. The light warns you when the ASC is turned off.
If there is a problem with the ASC, the most common problems are: 1) Failed switch in the console. 2) Damage or foreign objects in the wheel speed sensors. There are tooth wheels near the front brake rotors and on the rear axle. There are sensors near the toothed wheels that detect wheel speed. The the sensors must be the correct distance from the toothed wheel. If their wires are chaffed, or the toothed wheel is bent or broken, they won't work. 3) Poor connections on the ASC electrical connectors under the hood. Look on the ASC (outboard) throttle body and on the brake controller module. 4) I once put on a new throttle body rubber boot, and I left the screw on the hose clamp positioned at 12 o-clock, up on top of the boot. The ASC throttle arm collided with the hose clamp screw so the throttle motion was restricted. That set an ASC error code and illuminated the light.

How To How to Reset the Computer on a Nissan Sentra When the check engine light illuminates on the dash in a Nissan
Sentra, it is an indication that the computer has recognized a problem within its sphere of influence. Once the problem has been addressed and corrective action completed, the computer can be reset by erasing the existing codes.
jQuery('.intro .thumbnail').each(function(i,e){ jQuery(e).find('img').one('error',function(){ jQuery(e).remove(); }); });

Instructions Things You'll Need:

• Code scanner

1. Step 1 Insert the code scanner's connector into the OBD port located under the dash to the right of the steering column.
   
2. Step 2 Turn the ignition key to the run position. Make sure the engine is off.
   
3. Step 3 Press the button for "Read" on the code scanner. Within less than 1 minute, the scanner will display all failure codes that are stored in its memory.
   
4. Step 4 Write down the failure codes displayed by the scanner. Cross-reference the codes with the code sheet that comes with the scanner. The codes are displayed with a letter followed by a four-digit number code. Deciphering these codes by cross-referencing them with the code sheet offers an explanation of the failure.
   
5. Step 5 Turn the key off. Correct the failure so that the computer can be reset.
   
6. Step 6 Turn the ignition key on, keeping the engine off. Press the "Erase" button on the scanner. Start the vehicle and allow it to run for 5 minutes. Watch for the check engine light to come back on. If it does, the problem has not been corrected. If it stays off, the problem has been successfully resolved.
   

The flashing check engine light would mean that the engine is misfiring, If you have a scanner, use it on the diagnostic port of the engine to check for the error code to get which cylinder is misfiring and if there are other errors that needs to be checked.

ASC is short for "automatic stability control" u will need to have the ABS/Traction control system tested by the dealer for a possiable fault code.
