DTC 22 - Driver-Side Deployment Loop Resistance Low: Description
When ignition is first turned to RUN, inflatable restraint control module performs tests to diagnose internal critical malfunctions. Inflatable restraint control module monitors IGNITION 1 and deployment loop voltages for respective voltage. Inflatable restraint control module proceeds with RESISTANCE MEASUREMENT test. During one portion of RESISTANCE MEASUREMENT test inflatable restraint control module grounds DRIVER-SIDE LOW terminal No. 3 through internal current sink, connects DRIVER-SIDE HIGH terminal No. 2 to internal constant current source which drops voltage in deployment loop, measures voltage difference between DRIVER-SIDE HIGH and DRIVER-SIDE LOW, and calculates resistance of passenger deployment loop using measured voltage.
