Inside the diagnostic box. Connect separate wires to terminals Tc and AB.

Turn the ignition switch to ACC or ON and wait approx. 6 secs.

Ground to chassis the wire connected to the TC. Then unground and ground the wire connected to terminal AB.

Do this twice each, in cycles of 1.0 0.5 seconds.

After the last cycle. Continue grounding terminal Tc.

Note, when alternately grounding terminals Tc and AB. Unground one terminal and immediately ground the other. The action must be done within the time limit. If not done within the time limit, repeat the procedure until code clear.

If successful. Several seconds after performing the procedure. The SRS light will blink in a 50 m sec. cycle to indicate the codes have been cleared. Then turn off ign. Remove wires.

Hello Joey,

Finally got everything back together. No luck with the airbag light. I tried what you suggested and it seems to "almost" work. I can get the light to shut off and then blink as if it is resetting; however, when I remove the ground AB wire the light comes back on and stays on.

Thanks for your help.

Could be technique.

Ground Tc wire to chassis for 1sec +/- 0.5sec. SRS light should be off when Tc is grounded.

Unground Tc and immediately ground AB for 1s +/-0.5s. SRS should be on.

Unground AB and immediately ground Tc wire to chassis for 1s +/- 0.5s. SRS light should be off.

Unground Tc and immediately ground AB for 1s +/-0.5s. SRS should be on.

Unground AB and immediately ground Tc for SEVERAL sec. SRS light should start to blink if codes are clear. After blinking, unground Tc.

Thanks again. I'll keep trying. Does the ignition have to be turned off before ungrounding Tc?

Hope you are enjoying your weekend.

NO. If/when the SRS light flashes, the codes are now cleared. Can then remove wire and turn off ign.

For the procedure to be successful. The manual is ADAMANT about doing the ground/unground procedure in the times specified.
