The D4 light blinks when the computer that controls your transmission has detected a problem...either with internally or with one of the information inputs it uses. The check engine light is on because a failure in the transmission can affect the overall emissions produced by your car. Lastly, the fact that your speedometer won't read speed tells me to first check the sensor that relays that information. On your car, and many others, a sensor called the Vehicle Speed Sensor reads rpm in the output shaft of the transmission. This information is used by the transmission and engine computers for a variety of needs. It is also passed on to the speedometer to provide speed information to the driver. I suspect the sensor is bad, but it will take a special peice of equipment called a "scan tool" to verify. The scan tool connects to the on board computers and allows the user to see the same information the computers are seeing. For help in locating a local mechanic, visit www.autoservicetech.com
Don't know what you're working on but it sounds like you have accidently disconnected the speedometer cable from the speedometer. Check it out.
The check engine light comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, a check engine light is lit when there is a problem in the emissions or somthing that is affecting the effectiveness of the emissions.
If you turn on your 1999 mustang v6 car and the right signal light stays on and doesn't blink and you switch the car off and then the left signal light stays on without blinking, then you need to see a mechanic.
I assume you have a 96 and up vehicle. If the light is blinking and then eventually it will stay on, it's always been a misfire code for me. Take your car to an autozone or advance auto parts and they will read the code for you. It will usually be plugs, wires, or a coil, depending on your car. Hope this helps.
The odometer stays on for a while so that service personnel have time to record the mileage when, say, getting your oil changed. It uses very little power.
You need to have it checked for codes with a scan tool. Once you know the code, you can diagnose the cause.
Hi, You need to check the brake fluid reservoir, it may only be about 5ml out, but that's what caused the same problem on our 97 Odyssey , i tried topping it up after mechanics couldn't fix the problem. Hasn't been a problem since:-)

Defective turn signal switch.
Check the front directional bulb
Yes, and so you should. It is called the 'cursor' and indicates the position that any text you enter will start.
If it keeps doing that all the time and dont starts check your key the key that you may have is a security key and what it does is that it does that on your dasch board odometer, you may have a security key the have a sensol right onb the middle of the key so check that out ok....
