Hi Everybody,
An update on my TOD woes:
I decided to get the TOD fixed since it appears you should not drive for very long with it in this condition.
I traced the problem to the rear speed sensor but I couldn't get it out. BTW-If you follow the troubleshooting guide in the manual it can lead to a misdiagnose of a bad TOD computer.
At this point I decided to get some help. It is at a auto repair facility with some Isuzu experience.
They found that the speed sensors can be bought from Ford. Go figure.
The also diagnosed both sensors as being bad so they replaced both of them.
However, as of Friday they were still getting the front and rear speed sensor errors, 14 and 24.
It is believed this is a wiring problem so they will continue next week.
I will post an update once it is fixed with details.
Bill
