Hi, all first post, hoping I can find my answer here. I have an obsolete part on my truck and I need to bypass it to continue to use the truck.
It is a 2000 ford f350 automatic 4x4 truck with a variable reluctance sensor on the rear axle that read a 120 tooth ring that creates a signal then it runs through the broken, obsolete ABS
module and the to the PCM and GEM to run the speedometer and partial shifting strategies for the auto trans.
Ive found online that the signal from the sensor is supposedly a pulsing DC signal and that the module supposedly converts it to a square wave for
the other modules to read. I would like to build a simple circuit to get around my broken module.
I have partially dissassembled the module but do not want to destroy it to inspect the chip side so I am waiting on a new soldering iron and desolder wick
to properly dissassemble it.
I have looked for replacements and repairs but no luck.
I am looking on Ebay to buy a Fluke 123 scopemeter to determine what the signals are but I will need help deciphering them and figuring out what to build.
Thank you very much in advance for any and all help. - A
