Circuit | Short to Ground | High Resistance | Open | Short to Voltage | Signal Performance |
---|---|---|---|---|---|
Passenger Instrument Panel Air Bag High Circuit | B0019 02 | B0019 0D | B0019 04 | B0019 01 | B0019 0E |
Passenger Instrument Panel Air Bag Low Circuit | B0019 02 | B0019 0D | B0019 04 | B0019 01 | B0019 0E |
If a malfunction is detected, a DTC will be stored in non-volatile memory. During a side or frontal crash of sufficient force the inflatable restraint sensing and diagnostic module (SDM) will allow current to flow through the deployment loop in order to deploy the passenger instrument panel air bag. The SDM performs continuous diagnostic tests on the deployment loops to check for proper circuit continuity and for shorts to ground or voltage. There are 2 shorting bars used within the passenger instrument panel air bag connector which will short together both high and low circuits, when the connector is disconnected. This will help to prevent unwanted deployment of the air bag during servicing.
Ignition voltage is between 9-16 volts.
The passenger instrument panel air bag high and/or low circuit is shorted to voltage.
The passenger instrument panel air bag high and/or low circuit is shorted to ground.
The passenger instrument panel air bag high and/or low circuit is open.
The passenger instrument panel air bag deployment loop resistance is more than 3.54 ohms.
The passenger instrument panel air bag deployment loop resistance is less than 1.77 ohms.
• | The SDM commands the AIR BAG indicator ON via serial data communications. |
• | The SIR System is disabled and no deployments are allowed. |
• | The condition responsible for setting the DTC no longer exists and the scan tool Clear DTCs function is used. |
• | A history DTC will clear once 255 malfunction-free ignition cycles have occurred. |
Note: When removing connectors inspect for damage or corrosion. Damage or corrosion in the following requires repair or replacement of the affected component/connector. • Passenger instrument panel air bag • SDM • Passenger instrument panel air bag wiring harness connector • SDM wiring harness connector
⇒ | If any of the above conditions are found make the appropriate repair. |
⇒ | Replace the passenger instrument panel air bag. |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
• | Control Module References for SDM replacement, setup, and programming |
