Symptom Troubleshooting
'99-01 Models
When the ignition key is turned to the ON (II) position,
the SRS control unit performs a self-test that takes
about 6 seconds. During the self-test, there is not any
voltage from the control unit going to the SRS indicator
circuit. This turns the indicator on. If the self-test is OK,
the control unit will send about 8.5 V to the SRS
indicator circuit. This turns the indicator off.
