B1035

When measurements are requested in this chart use J 39200 Digital Multimeter with correct terminal adapter from J 35616-A Connector Test Adapter Kit. When a check for proper connection is requested, refer to Intermittents and Poor Connections in Diagrams. When a wire, connector or terminal repair is requested, use J 38125-A Terminal Repair Kit and refer to Wiring Repair.

CIRCUIT DESCRIPTION
During the normal, non-deployment operation of the SIR system, a small amount of current flows through the driver deployment loop. The diagnostic resistors within the inflatable restraint arming sensor and the inflatable restraint discriminating sensors along with the resistance of the inflatable restraint steering wheel inflator module cause voltage drops within the deployment loop. The inflatable restraint Diagnostic Energy Reserve Module (DERM) monitors the voltage at the Driver Side Low terminal B8 to detect shorts or opens within the deployment loop. When the measured voltage is within a specified percentage of the Driver 36 VLR power supply for 500 milliseconds, DTC B1035 is set.

CONDITIONS FOR SETTING THE DTC
During continuous monitoring, the voltage measured at the Driver Side Low terminal B8 is within a specified percentage of the Driver 36 VLR power supply voltage for 500 milliseconds.

ACTION TAKEN WHEN THE DTC SETS
The DERM turns on the AIR BAG warning lamp and sets a diagnostic trouble code.

CONDITIONS FOR CLEARING THE DTC
The voltage measured at the Driver Side Low terminal B8 is above or below the percentage of the Driver 36 VLR power supply voltage which sets DTC B1035.

DIAGNOSTIC AIDS
An intermittent condition may be caused by one of the following:
- An improper connection at any of the inflatable restraint discriminating sensor terminals
- An open in one of the ground feeds to the inflatable restraint discriminating sensors
- An open inflatable restraint discriminating sensor interconnect circuit
- An increased resistance of one of the inflatable restraint discriminating sensors
- A decreased resistance of the inflatable restraint arming sensor

TEST DESCRIPTION
1. Start at the SIR Diagnostic System Check for all diagnosis.
7. This test checks for increased resistance of the LH forward inflatable restraint discriminating sensor.
8. This test checks for an open in the ground feed to the LH forward inflatable restraint discriminating sensor.
11. This test locates the open in the ground feed to the LH forward inflatable restraint discriminating sensor.
19. This test checks for increased resistance of the RH forward inflatable restraint discriminating sensor
21. This test checks for an open in the ground feed to the RH forward inflatable restraint discriminating sensor.
24. This test locates the open in the ground feed to the RH forward inflatable restraint discriminating sensor.
27. This test checks for an open in the inflatable restraint discriminating sensor interconnect circuit.
29. This test checks for a malfunctioning inflatable restraint arming sensor.
