SIR Schematics (30 Series Pickup): Fuse Block, Inflatable Restraint Sensing And Diagnostic Module:

The inflatable restraint side impact sensor (SIS) circuit Consists of a side impact sensor (SIS), the SIS signal circuit, and the SIS voltage circuit. When the ignition is turned ON, the inflatable restraint sensing and diagnostic module (SDM) performs tests to diagnose critical malfunctions within itself. The SDM provides input power to the SIS. When input power is first detected, the 518 responds by performing internal diagnostics The SIS then sends an ID message to the SDM. The SDM will consider this to be a valid ID if the response time is less than 5 seconds after the 815 is powered up. The SIS will continually communicate a status message to the SDM The SDM is capable of resetting the SIS by removing and applying power to it.

CONDITIONS FOR RUNNING THE DTC
Ignition 1 voltage is within the normal operating voltage range.

CONDITIONS FOR SETTING THE DTC
The SDM has received a NOK (not OK) message from the right SIS.

ACTION TAKEN WHEN THE DTC SETS
The SDM commands ON the AIR BAG indicator via Class 2 serial data.

CONDITIONS FOR CLEARING THE DTC
^ The condition responsible for setting the DTC no longer exists
^ You issue a scan tool CLEAR DTCs command
^ A history DTC will clear once 255 malfunction free ignition cycles have occurred.

TEST DESCRIPTION

Steps 1-4:

The following number refers to the step number in the diagnostic table:
2. Tests the communication status of the right SIS.
