What does differential mag pulse generator feed: ABS+Speedo+Odo+Cruise?

posted by  someone claiming to be io333 on  Sat Mar 27 15:25 CST 2004 [RELATED]

Hi all. I'm still trying to figure out what my speedo and odo are dead.

I have some questions to help me narrow down possibilities. Does the pulse generator in the differential feed:

1. ABS for rear wheels?

2. Cruise control *directly*, or does the signal get modified before going into the CC computer?


The reason I ask, is because I don't understand why the pulse generator, or the wiring from it might be bad, when my ABS system is functioning perfectly, and has not turned on the dash warning light. Is it possible that there is still sufficient pulse to let the ABS think that things are OK, but it is still not strong enough to make the speedometer and odometer run? Also, my Odo started working intermittently for a while, and then died completely, before the speedo died, or stuck constantly at 45mph. Is this consistent with a dying pulse generator?

I'm pulling the differential cover off monday to clean off the generator to see if that helps. Should I just replace the thing while I'm at it? How much does a new pulse generator cost? Is replacement procedure obvious and simple, or do I have to measure & align stuff?
