The entire dash electrical pod as an assembly may be loose . I would take it out and inspect it and the contacts where it plugs in.
If the ABS light is flashing it means the system is malfunctioning but still working. The dash light behind the speedometer is burnt out.
It means your alarm is armed
Drive as fast as you can and ignore the flashing lights behind you!
speed sensor is out or is going out. your speedometer is out too right?
Sounds like you need a speed sonsor
A flashing D4 light on Honda Accords is commonly the result of a bad speed sensor. The speed sensor is located on the transmission and sends a signal to the speedometer and a signal telling the transmission when to shift.
You're screwed
You can do it with a scanner. Usually when the security light is flashing it means there is a problem with the passlock system. Dealer item and about $500.00-$700.00 to replace parts & reprogram.
Could be several reasons. Start with having the codes read. The codes will guide you towards the cause.
turn key to on position ,but do not try to start until antitheft light quites flashing. It may take 5 to 10 minutes. When antitheft light quites flashing you should be able to start your car. If not repeat the procedure.
The s3 light coulb be your speedometer cable if it is not working mine did that i hope this works.
With the key in the off position, hold down the trip odometer reset button until the dash lights start flashing. When it is all done start the car, and see if it reset.
