Speedometer/odometer/cruise control isn't working.

Hi Wendy. My name is Tim Dorton, I was a Nissan Senior Tech. The Frontier manual and auto transmissions are the same as far as the odometer is concerned. The computer uses the signal from the speed sensor to control the cruise control, speedometer, and determine mileage. Does the speedometer and cruise control work? If so the the problem is most likely in the guage cluster. Here is the wiring from the speed sensor.

The plastic gear in the back of the instrument panel is known to crack and break, this may have happened, A trip to the auto-recycler may net you a new-to-you speedo cable!

You could have a faulty speedometer/odometer combination meter causing a false Vehicle Speed Sensor error.
My 1998 Sienna had the following symptoms:
- Speedometer and odometer failed intermittently
- The check engine light would come on and I would get a p0500 code in the OBDII.
- The cruise control would stop working at the same time the speedometer failed.
There is a speed sensor in each one of the tires and they feed the speed information to the ABS ECU. From the ABS ECU the speed signal goes to the speedometer/odometer combination meter, and from there it goes to the Engine Control Module and to the Cruise Control ECU. I could see a signal coming into the speedometer/odometer, but no signal going out. Replacing the speedometer/odometer combination meter fixed the problem.

Your computer was not upgraded when the recall was done, take to dealer and tell them to upgrade your computer to reflect the changes made during the recall.

If the speedometer does work, but the odometer doesn't work, then you have a bad speedometer head assembly. The speedo head is a microprocessor that gathers the info coming from the vehicle speed sensor and translates it for you on the speedo and the odo. If one is working, but the other isn't, then it is getting the VSS signal, it just isn't processing it right. You could also be experiencing the below issue: The Brake Pressure Differential Deactivation Switch (SCDS) (2B264) located under the Master Cylinder (Behind the Air Filter) over time develops a leak. This causes a short and a fuse trip, fuse #10 if the engine is on. This leak also causes brake fluid to wick down two wires to the ABS brake module (2C219). The fluid accumulates on the (always on) power connectors for the ABS brake system which are powered by fuses 101 and 102 and are both 40 amp. The fluid attacts moisture, road salt and leads to a fire when the fluid and moisture act as conductor between the hot leads and ground. This switch has been the subject of other Ford Recalls, just not the Windstar van yet. Below is a picture of the switch in question. Notice the fluid that leaked on the part below it. This switch will cause cruise control problems, speedometer, odometer and ABS brake system problems.

It is most likely the speed sensor in the transmission.

yes the transmission speed sensor has most likely failed, to confirm this have a trouble code test run

replace the Vehicle Speed Sensor on the trans.

you have a problem with your speed sensor, you need to check or replace it.

Probably bad vss (vehicle speed sensor). No Cruise operation without speed sensor input to engine control module.
