Circuit Description

When you first turn the ignition switch to the RUN position, the inflatable restraint sensing and diagnostic module (SDM) perform tests to diagnose critical malfunctions within itself. Next the SDM measures the IGNITION and the deployment loop voltages to make sure they are within their respective normal voltage ranges. Then the SDM proceeds with the RESISTANCE MEASUREMENT test. During one portion of the RESISTANCE MEASUREMENT test, the SDM does the following:

    • Grounds the Passenger Belt Low terminal 15 through an internal current sink.
    • Connects the Passenger Belt High terminal 45 to an internal constant current source. This current produces proportional voltage drops in the deployment loop.
    • Measures the voltage difference between Passenger Belt High and Passenger Belt Low.
    • Calculates the resistance of the passenger seat belt pretensioner deployment loop using the measured voltage.

Conditions for Setting the DTC
    • The passenger seat belt pretensioner deployment loop is not open.
    • The passenger seat belt pretensioner deployment loop is not shorted to voltage.
    • The passenger seat belt pretensioner deployment loop is not shorted to ground.
    • The passenger seat belt pretensioner deployment loop resistance is more than 2.85 ohms. The passenger seat belt pretensioner deployment loop consists of the following components:
       - Passenger seat belt pretensioner.
       - Harness wiring of CKT 2116.
       - Harness wiring of CKT 2117.
       - Connector terminal contact.

The RESISTANCE MEASUREMENT test checks for this malfunction. This test only occurs once each ignition cycle when IGNITION is within the normal operating voltage range.

Action Taken When the DTC Sets
    • The SDM sets a DTC B1030.
    • The SDM turns ON the AIR BAG warning lamp.

Conditions for Clearing the DTC
    • Current DTC
        The resistance of the passenger seat belt pretensioner deployment loop is less than 2.3 ohms and the ignition switch is cycled.
    • History DTC
       - You issue a scan tool CLEAR CODES command.
       - Once 250 malfunction free ignition cycles have occurred.

When you issue a scan tool CLEAR CODES command and the malfunction is still present, the DTC will not reappear until the next ignition cycle.

Diagnostic Aids

A poor connection can cause an intermittent condition. Check the following for a poor connection:

    • The passenger seat belt pretensioner wiring harness connector terminal A and terminal B.
    • The SDM wiring harness connector terminal 45 and terminal 15.
    • The wire to terminal connections in CKT 2116.
    • The wire to terminal connections in CKT 2117.

The diagnostic table directs the technician to note the entry value of RH PRETENS. RESIST. Comparing the value of RH PRETENS. RESIST. over multiple ignition cycles can be helpful in determining if an intermittent condition exists.

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

Test Description

The numbers below refer to the step numbers on the diagnostic table:

  1. This step checks the passenger seat belt pretensioner yellow 2-way wiring harness connector for corrosion or damaged terminals.

    2.

  2. This step isolates the malfunction to one side of the passenger seat belt pretensioner yellow 2-way connector.

    3.

  3. This step checks the SDM wiring harness connector for corrosion or damaged terminals.

    4.

  4. This step checks to see if there is a high resistance in CKT 2117.

    5.

  5. This step determines if there is a high resistance in CKT 2116 or if there is a malfunctioning SDM.
