TEST B: BATTERY VOLTAGE OUT OF RANGE - DTC B1676
1. Check if vehicle has been jump started within past 2 weeks. If vehicle has been jump started, ABS is
okay. If vehicle has not been jump started, go to next step.
2. Using DVOM, measure voltage between positive and negative battery terminals. If voltage is 9-19 volts,
go to next step. If voltage is not 9-19 volts, diagnose charging system. See appropriate GENERATORS
article in STARTING & CHARGING SYSTEMS.
3. Turn ignition off. Disconnect 25-pin ABS control module. Install EEC-IV 60-pin Breakout Box (014-
00322). Turn ignition on. Measure voltage between breakout box terminal No. 20 and ground. If voltage
is more than 10 volts, go to next step. If voltage is less than 10 volts, repair Light Blue/Pink wire between
ABS control module and instrument panel fuse panel.
4. Turn ignition off. Measure voltage between breakout box terminal No. 25 and ground. If voltage is
greater than 10 volts, go to next step. If voltage is less than 10 volts, repair Red wire between ABS
control module and power distribution box/engine compartment fuse box.
5. Measure voltage between breakout box terminal No. 9 and ground. If voltage is greater than 10 volts, go
to next step. If voltage is less than 10 volts, repair Yellow/Light Green wire between ABS control module
and power distribution box/engine compartment fuse box.
6. Measure resistance between breakout box terminal No. 8 and ground. Also, measure resistance between
breakout box terminal No. 24 and ground. If both resistance measurements are less than 5 ohms, replace
ABS control module and repeat self-test. If either resistance measurement is greater than 5 ohms, repair
suspect Black wire between ABS control module and ground distribution.
NOTE: DTC B1676 will set if vehicle has been jump started.

If the problem you are having is that anywhere below 30 mph your odometer goes all over but at 40 mph and above it is fine. Also your ABS light is continuously remained on the whole time.
This problem is a 15 to 20 min fix. Go down to your auto parts store and it will cost you under $20.00. The name of the part that you will need is called a magnet speed control sensor. This is located on top of your rear differential. You will have to crawl under your truck with a 3/8 inch wrench to get the job done. Good Luck!

This might help a ton and save you money! So easy to fix, this video sounds like the same problem described! ABS light on, o/d flashing, check engine light on, tranny seems to be having issues, speedometer stops working. All fixed as described by the first answer james_hust , not tying to take your mojo but the video shows you what you need to do.
