Diagnostic Trouble Code Chart

  1. DTCS FOR SUPPLEMENTAL RESTRAINT SYSTEM 

    If a trouble code is displayed during the DTC check, check the circuit listed for the code in the table below (Proceed to the link listed for that circuit).

    HINT:

    • When the SRS warning light remains on and the DTC output is the normal system code, a voltage source drop is likely to occur. This malfunction is not stored in the memory by the airbag sensor assy center. If the power source voltage returns to normal, the SRS warning light will automatically go off.
    • When 2 or more codes are indicated, the code with the lower number appears first.
    • If a code is not listed on the display chart, the airbag sensor assy center may have failed.
    • In the case of any malfunction concerning an open circuit, short to ground, or short to B+ due to a squib, other trouble codes may not be detected. In this case, repair the malfunction currently indicated and then perform malfunction diagnosis again.
    • Mark in the check mode column:

      "x": The DTC is corresponding to the check mode.

      "-": The DTC is not corresponding to the check mode.

    • When DTC B1650/32 is detected as a result of troubleshooting for the supplemental restraint system, perform troubleshooting for the occupant classification system as shown in the chart below.
