is on! How do I diagnose this? ODB (1) code reader only addresses check engine light?
Thanks!

 

There are ABS capable code readers, you'll need one of those to be able to read ABS codes.

 

for the info does anyone know a model of scanner that can do the abs codes? Hate to have to go to the dealer as I am a poor person and they will charge me $100 just to look at it, ouch.
Thanks

 

You may not need a scanner... if it works the way the trucks do (worth a shot..), try this... I use this for my 95 ram truck. (just like cycling the ignition 3 times in under 5 seconds works to display codes by flashing the check engine light....) My van is newer and obd2 so I can't check it to see... give it a try and see if it works... I'm curious...

To read the codes on 96 and older trucks:

1. turn key to the "on" position.

2. for just a second, ground pin # 13 on the diagnostic plug located on the knee bolster (#13 is a black wire, it's the 4th from right bottom row).

watch your ABS/Brake light for codes.

start counting with the first long flash, end with last short flash.

there are only 13 codes.

1. Not used.
2. open isolation valve wiring or bad control module.
3. open dump valve wiring or bad contol module.
4. closed rwal switch.
5. not used 4wd. over 16 dump pulses in 2wd.
6. erratic speed sensor reading. (most common)
7. electronic control module fuse pellet open, isolation output missing, or valve wiring shorted to ground.
8. dump output missing or valve wiring shorted to ground.
9. speed sensor wire resistance/ high reading.
10. speed sensor wire resistance/ low reading.
11. brake switch always on, RWAL light comes on over 40mph.
12. not used.
13. electronic control module phase lock loop failure.
14. electronic control module program check failure.
15. electronic control module RAM failure.

 

thanks will try
