Okay...I ended up tripping a SRS code on my 1998 T-100 SR5 2WD auto when I had to move the passenger side (right) airbag sensor cable while doing my stock air box mod.
After staring at it fer about a week...I decided to read the code and then reset it.
To read the code, I got about 8' of network cable and stripped back 1" from 2 wires. I located the Diagnostic port in the engine bay and plugged one wire into the 3rd column 1st row (E1), and the other wire into 5th column 2nd row (Tc).
Brought the unattached end of the cable into the cab of the truck.
Connected both wires together.
Turned the ignition to the ACC position.
Read the flashes...one...five.
Code 15..."Open in front air bag sensor circuit".
Turned the key back to the LOCK postion.
Disconnected the wires (no longer touching each other) and moved the 1st wire to the 4th column 1st row (AB).
Turned the key to the ACC position.
Wait at least 6 seconds.
Using the visor screw as a convenient ground point, I held the Tc wire to the screw fer 1 second.
Removed the Tc wire and immediately held the AB wire in place fer 1 second.
Removed the AB wire and immediately held the Tc wire in place fer 1 second.
Removed the Tc wire and immediately held the AB wire in place fer 1 second.
Removed the AB wire and immediately held the Tc wire in place until I saw the code reappear.
Removed the wire from touching the screw.
Turned the key to the LOCK position and leave it in that position fer at least 20 seconds or more.
Turned the key to the ACC position.
The airbag indicator should light fer about 6 seconds and then turn off. If it still stays on repeat the process above until you git it right.
