Connect an oscilloscope between passenger airbag #1 and #2. Check for an intermittent short-circuit to supply voltage according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
The oscilloscope should now display a spiked pulse with an interval of approximately 500 ms.
Also take a reading between ground and airbag #2. The oscilloscope should read approximately 2 V.
The cable harness must be replaced if there is a fault in the wiring. No repairs may be made to the cable harness.
Remedy as necessary.
