DTC 036
DTC 36
CIRCUIT DESCRIPTION
The inflatable restraint instrument panel (I/P) module deployment loop consists of a inflatable restraint I/P module the I/P module high and I/P module low circuits. A shorting bar is used in the inflatable restraint I/P module connector which will short together the I/P module high and I/P module low circuits when the connector is disconnected, this will help to prevent unwanted deployment of the inflator module during servicing. During a frontal crash of sufficient force the sensing and diagnostic module (SDM) will allow current to flow through the deployment loop in order to deploy the inflatable restraint steering wheel module. The SDM performs continuous diagnostic tests on the deployment loops to check for proper circuit continuity and for shorts to ground or voltage. If a malfunction is detected a DTC will be stored.
CONDITIONS FOR RUNNING THE DTC
Ignition voltage is within the normal operating voltage range.
CONDITIONS FOR SETTING THE DTC
- DTC 35 will set when the SDM detects a high capacitance condition in the I/P module deployment loop.
- DTC 36 will set when the SDM detects a low capacitance condition in the I/P module deployment loop.
ACTION TAKEN WHEN THE DTC SETS
The SDM commands the AIR BAG indicator ON.
CONDITIONS FOR CLEARING THE DTC
The condition responsible for setting the DTC no longer exists and the scan tool Clear DTCs function is used.
DIAGNOSTIC AIDS
Thoroughly inspect the wiring and the connectors. An incomplete inspection of the wiring and the connectors may result in a misdiagnosis, causing a part replacement with the reappearance of the malfunction.
The following are possible causes of the malfunction:
- A high capacitance in the inflatable restraint I/P module inline capacitor.
- A low capacitance in the inflatable restraint I/P module inline capacitor.
If an intermittent malfunction exists, refer to Testing for Intermittent and Poor Connections in Diagrams.
