Hi I just bought a 99 black FRC. I love it, but the odometer doesn't work. Is there anyway the previous owner could have disconnected it. I would like to hook it back up.

 

Does the speedometer still work?
Maybe the previous owner disabled the odometer so that his driven miles don't show It's a cruel world...

 

Just a thought but if you just bought it have you tried the trip button to the right of the stearing wheel. Not sure how much you have played with yet and not sure what's not working?

 

The speedometer is working and it's not on TRIP. I don't know. Is there a cable that can be unhooked from the trans?

 

So you can see the odometer numbers while driving but there is no change? Just trying to see what your up against.

 

yes, exactly

 

Heres the troubleshooting guide

Hopefully its a bad connection at either the PCM or the IPC

1. Install a scan tool.
2. Raise the vehicle's drive wheels. Refer to Lifting and Jacking the Vehicle in General Information.
3. Start the engine.
4. Place the transmission into drive for automatic transmission and third gear for manual transmission.
5. With the scan tool, observe the Vehicle Speed parameter in the PCM Engine Data 1 data list.

Does the Vehicle Speed parameter match the speedometer display?

1. Turn the ignition OFF.
2. Disconnect the PCM connector C2.
3. Turn the ignition ON, with the engine OFF.
4. Measure the voltage from the vehicle speed signal circuit to a good ground.

Does the voltage measure greater than the specified value?


9.6 V

Thats what I was gonna say! all joking aside that was a great reply

 

The speedo is electric not mechanical if im not mistaken.
