Conditions For Setting DTC

WARNING: This page is about a different car, the 2000 Buick Park Avenue. However, it is still accessible from the selected car via links, so may be relevant.

DTC sets when driver deployment loop voltage and resistance tests are not within specified ranges.

DTC will set if DEPLOYMENT LOOP VOLTAGE test is within the following ranges:

IGNITION POSITIVE VOLTAGE is within normal operating range.
Deployment loop is not shorted to voltage.
DRIVER HIGH voltage is less than 2.4 volts.
Deployment loop resistance is at least 6 ohms for 500 milliseconds. DTC will set if DEPLOYMENT LOOP RESISTANCE test is within the following ranges:
IGNITION POSITIVE VOLTAGE is within normal operating range.
Deployment loop is not shorted to voltage.
Deployment loop is not shorted to ground.
Deployment loop resistance is greater than 4.8 ohms for 500 milliseconds.
