Control Module Grounding
The control module is grounded via the three securing bolts. No grounding leads from other systems may be connected to the control module securing
bolts as the function of the airbag may be disrupted and a fault indication be received by the control module.
Insufficient grounding will not produce a diagnostic trouble code. When the grounding contact is reestablished after having been broken, this is
equivalent to switching on the voltage and the control module restarts its self-test and the SRS lamp lights for 3 to 4 seconds.
If the grounding contact is again broken during these 3 to 4 seconds, this is equivalent to the voltage being switched off and the lamp goes out. If the
grounding contact both breaks and returns during the 3 to 4 second period, this is equivalent to the voltage being switched on and off, which makes the
SRS lamp flicker.
