ABS, Brake warning, Engine check lite up. Tach, Speedo, mileage
2009 Honda Accord. I am told that the remote tire monitor system or ECM (what is that) can be affected by a single CB radio transmission. (outside the car antenna and radio is in a metal box under driver's seat and the antenna is fed with groounded-shield coax!!) When told that my 1997 Toyota Avalon had a 100 watt ham radio and 12 watt SSB CB, the tech said, ''yeah but it does not have the tire monitor system.'' Mabe that is why I have never seen a police car with all their electronic gadgets being a Honda. Walt.

Re: ABS, Brake warning, Engine check lite up. Tach,...
THE SENSORS FOR TIRE PRESSURE ARE INDEED MINIATURE RADIO TRANSMITTER'S, THE FREQUENCY OF THAT SIGNAL IS NOT IN THE SPECIFIED IN THE FACTORY SERVICE MANUAL, SO YES IT IS POSSIBLE FOR THE SIGNALS TO BE INTERFERED WITH BY A CB RADIO TRANSMISSION, BUT THE TRANSMISSION SOURCE WOULD HAVE TO BE VERY CLOSE. ECM STANDS FOR "ELECTRONIC CONTROL MODULE", THE SYSTEM IN THE CAR THAT MONITORS TIRE PRESSURES IS CALLED A "TPM", OR TIRE PRESSURE MONITOR, IT CONSISTS OF 5 SENSORS (4 TIRES AND SPARE) THAT ARE RADIO TRANSMITTERS AND A RECEIVER THAT RECIEVES IT'S SIGNAL FROM THE WHEEL MONITORS THROUGH THE ANTENNA OF THE CAR. DO U HAVE A PROBLEM WITH THE TPM SYSTEM?

You need to have the vehicle scanned for fault codes and then the causes of those codes diagnosed.
You will need to have this car checked out by a professional with the right diagnostic equipment for Hondas. The Vehicle Stability Assist (VSA)***, brake and ABS warnings may just be due to a failed sensor or sensors but you need to have a proper diagnosis carried out so the causes can be identified and any failed parts replaced.
The flashing D light relates to the auto transmission and may well be a caused by a faulty sensor on the transmission or something else. The correct scanner should throw up any fault codes being generated. In the meantime if your Accord model has the engine bay filler tube and diptstick for the auto transmission , check your fluid level in the auto transmission.
Only if the warning light showed on the dash...most often these abs sensors get clogged with brake dust or dislodged during wheel swaps if the pads are fine and fluid level correct...first check the brake pads then the disks and clean the sensors with an old toothbrush and reseat, also check the fluid level on the abs system.this should clear warning light.but any error codes stored on ecu need to be cleared using obd.
I HAVE RUN ACROSS SOME WEIRD STUFF ON THESE VEHICLES EX. TACH, SPEEDO, RADIO ,LIGHTS AND SO ON ,,WATER /MOISTURE WAS FOUND IN THE TRANSMISSION RANGE SWITCH ( NEUTRAL SAFETY SWITCH )CONNECTOR ,,,THAT WAS CAUSING SOME MAJOR TECHNICAL DIFFICULTIES ,I REPLACED THE SWITCH AND CONNECTOR AND THAT SOLVED IT , , I DON'T KNOW WHAT ALL THE SYMPTOMS ARE FOR THAT PROBLEM BUT I WOULD DEFINITELY CHECK IT OUT ,,,
the abs control unit controls the speedo (tach) also tells the cruise signal. abs should be fixed or replaced for any of these to work properly with the abs system not working you have no signal to the ecu to say what fuel air mix is for the speed you are doing and will think you are idling.
To my knowledge, the ABS light coming on indicates that the system has been disabled for some unknown reason(s). This would then translates to your vehicle having only standard/conventional power brakes, but brakes you will still have.
The correct procedure would be to have your ABS Brake Code scanned and interpreted.
The ABS warning light could be triggered by faulty sensor in any of the wheels or damaged wiring/connector or worst case scenario defective ABS module, pump or motor. Alternately, you try to fill the reservoir up. Normally, there would be a rubber cap andanother plastic cap under it. Add Honda brake fluid with the engine running. It would be preferable to do it slowly as to allow the air bubbles to escape. Additionally, pls check for any sign of leakage. If for some reason it would considerable fluid has to be added, it may be necessary to bleed the system. Pls reference this page for the procedures.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
