Speedometer does not work?

Hi PANTERANEGRA,

Seems you are describing a DTC code # 10 instead of # 1.
1 should be a short quick flash and a prolonged flash before it goes off is 10.

DTC # 1 = Lockup solenoid valve A problem.

DTC # 10 = Disconnected Engine Coolant Temperature sensor.

The symptom does not tally with the codes on display and I believe you need to substitute a TCM totest.

Hi PANTERANEGRA,

DESCRIPTION

Automatic transaxle is electronically controlled. Transaxle shifting and torque converter lock-up are controlled by Automatic Transaxle Control Unit (ATCU) for optimal performance. The ATCU receives information from various input devices and uses this information to control shift and lock-up control solenoid valves.

Vehicle is equipped with "S" (sport mode) switch mounted on shift lever in the vehicle. The "S" switch is used to change shift points under part throttle acceleration. When "S" switch is depressed with ignition on, "S" indicator light on instrument panel should come on and then go off when "S" switch is released.

Your symptom is consistent with a faulty TCM or its wire connections. When cold the TCM works ok, when heated up, resistance builds up or some of the TCM internal capacitors etc stops and when the brain senses a fault, it goes into fail safe mode (limp mode). When you turn ignition off, the TCM iresets and restarts woould have the TCM working normally till it senses any faults.

Hi PANTERANEGRA,

If the color of the trans fluid looks dark or brownish, it is best replaced. If it is bright red, it is still in good condition.

Regarding the window motor, what is the problem that you are facing? If it is sluggish, it usually is caused by the runchannels and not the motor. If the runchannel is distorted, especially near the wing mirrors, you need to replace it.

Hi,

The symptom indicates a failing brake master cylinder which is leaking internally. You need to repair/replace the master cylinder and bleed the system to rectify.

The bouncing comes from the cable binding up in the housing. Remove the speedometer gear from the transmission then remove the speedometer cable. Try pulling it out of the housing. If it is broken then you will have to disconnect it under the dash at the sppedometer. With it broken you may have to get a complete cable assembly.

Do you have a tach on the vehicle? If so does it still work? If not, I would suspect the sender and if so, the speedometer.

I would give the nod to the speedometer itself having failed. The sender is doing its job.

No not really because you will likely only find used parts and they are reasonable. I would check to see that nothing was disconnected during the alternator replacement and forgotten to be reconnected.
