Diagnostic Trouble Code Table

If a trouble code is displayed during the DTC check, inspect the trouble areas listed for that code. For details of the code, refer to the DTC No. below.

HINT:

• When the SRS warning light remains on and the DTC output is the normal system code, a voltage source drop has most likely occurred. This malfunction is not stored in memory by the center airbag sensor. If the power source voltage returns to normal, the warning light will automatically go off.
• When 2 or more codes are indicated, the code with the lower number appears first.
• If a code not listed in the table is displayed, the center airbag sensor may have malfunction.
• 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 the malfunction diagnosis again.
• When DTC B1150/23 is detected as a result of troubleshooting for the Supplemental Restraint System, perform troubleshooting for the occupant detection system as shown in DIAGNOSTIC TROUBLE CODE TABLE  .
• Mark in the check mode column:

  *1: DTC is not corresponding to the check mode.

  *2: DTC is corresponding to the check mode.
