2002 Tacoma SRS/Airbag ODB2 Code B1135

[b fig 2]

2002 Tacoma 2WD, standard transmission, base model. Issue: airbag / SRS light on dash comes on from time to time.

FYI: had the SRS Airbag Control Module refurbished about a year ago. Note: verified no loose connectors at module. Know rebuild doesn’t mean it didn’t go west again but my problem seems strange.

Getting ODB2 code B1135.

Just for easy reference, per internet search, various B1135 descriptions:

Malfunction of electrical connection check mechanism of airbag sensor assembly connector

“Airbag sensor assembly malfunction

Faulty Airbag Sensor Assembly Center

Airbag Sensor Assembly Center harness is open or shorted

Airbag Sensor Assembly Center circuit poor electrical connection”

When light comes on, read and clear code. Light stays off for a few days. Also, can turn the passenger side airbag off, run a few errands, get home and turn the air bag back on and once again light stays off for a few days. Not sure what the passenger side on / off switch has to do with clearing the code unless it is tied back to the control unit.

Other than a possible “flakey” control module would appreciate any other possible potential problem areas.

Thanks Bob

Come-on, where's jay?...your gen1 man. This should be in your wheelhouse. You've been calling other techs hacks for days.


On another note, it might be as simple as a faulty plug connection, or poor ground.
