About a months ago the brake dash light suddenly decided to stay one
Unpluged feeds from the parking brake switch and the brake pressure
switch..... no effect on the light
Then last week it started flashing out 6 dots and a dash, or a dash
and 6 dots, continuously when running.
I don't have ABS

Are those aliens trying to signal me.....again?

RWAL Fault codes
Codes for Dodge RWAL, Ford RABS and GM RWAL applications are similar but
have a few differences:

1.. Should not occur (replace the controller if it does)
2.. Open isolation valve circuit or defective ABS module
3.. Open dump valve circuit or defective ABS module
4.. Grounded or closed RABS or RWAL valve switch
5.. Excessive actuations of dump valve during ABS braking
6.. Erratic speed sensor signal
7.. Shorted isolation valve or defective ABS module
8.. Shorter dump valve or defective ABS module
9.. High resistance or open speed sensor circuit (resistance should be
1000 to 2500 ohms)
10.. Low speed sensor resistance (Dodge & Ford only)
11.. Open speed sensor circuit (GM only)
12.. Stop lamp switch circuit (Dodge & Ford)
13.. ABS module speed processor (Dodge & Ford only)
14.. ABS module program (Dodge & Ford only)
15.. ABS module RAM memory failure (Dodge & Ford)
To manually clear a stored fault code on GM and some Dodge trucks with RWAL,
remove the ABS fuse or disconnect the battery for 5 seconds. Ford RABS codes
will automatically clear when the ignition is turned to the off position.

6 flashes - Speed Sensor Fault. Probably dirty contacts or wiring is
chafed someplace. Notice any problems with the speedometer or the cruise
control?

Speedo is fine, while I've never used the cruise control feature. I'll
try it later today.
