95 Ranger, air bag code 33
I have searched the forum and found others that have had this problem but nobody has posted what they found as the cause or repair. Code 33 is high resistance for passenger side air bag (I think) but I don't think my kids truck has a passenger side bag. Is there a resistor or jumper at what would be the r/s harness? Can anyone shoot me in the right direction to try to troubleshoot and repair this? My kid is 16 so I would really like the driver side bag to work (I don't think it will with the light on) but don't have the cash to pay a repair shop to check/repair it. On the plus side I am a 25 year heavy truck mechanic, just don't do much automotive.
Any help is appreciated. Thanks,
Jeff.

FWIW, this is from a '96 For manual:
PASSENGER SIDE AIR BAG CIRCUIT HIGH RESISTANCE OR OPEN — LAMP FAULT CODE 33
Possible Causes
- An open circuit or high resistance in the wiring harness in either Circuit 607 (LB/O), Pin C1-5 or Circuit 616 (PK/BK), Pin C1-4, Circuit 1112 (W/LB) or Circuit 1113 (Y/LG).
- An open circuit or high resistance in the passenger side air bag module. Do not attempt a direct resistance measurement of the air bag. Follow the diagnostic procedure to determine if the air bag resistance is higher than normal.
- An open circuit or high resistance in the passenger air bag deactivate (PAD) switch.
It's interesting that, for 1996 (and probably '95), a 33 code could also be attributable to a PAD switch problem. This is not the the case in later models.
Which leads to the question: does the PAD switch lamp light up?

PAD switch lamp? I'm unsure what that is but will guess it is the passenger airbag disable? If so this truck doesn't have a passenger air bag disable switch, I'm pretty sure it doesn't have a passenger side air bag. That is what is confusing me about this fc.

Based on the scant information I can get from the service manuals from back then, the 1995 Ranger was only avaliable with a driver air bag. It had a 2 ohm simulator installed in the connector 242F in the area of the dash that would normally have the passenger air bag. If the simulator is missing from that connector, or the wiring is cut creating an open circuit then you would get the high resistance code. Otherwise the fault would be in the diagnostic monitor itself.

Well it's been a while but I finally popped the air bag cutout off on the passenger side dash last night (my '95 doesn't have the passenger side air bag). The wiring for the air bag (if it had one) runs up and is attached to the back side of the dash piece and the 2-ohm simulator is plugged into the end of it. Mine tested at 6 ohms. I plugged and unplugged the simulator end a couple times to try to clean the connections "just in case" and wouldn't you know that was all the problem was. Air bag light went off. If it does come back on again I will try to round up a new simulator since mine is out of spec.
Anyone that is thinking about testing theirs should know it's very simple to remove the dash cut-out. Use a large flat blade screwdiver and GENTLY pry it directly toward you (as long as you're sitting in the passenger seat). It's that simple.
Thanks guys for the help.
Jeff.
