AIRBAG SYSTEM > DIAGNOSTIC TROUBLE CODE CHART

for Preparation Click here


If a trouble code is displayed during the DTC check, check the trouble areas listed for the code in the table below (refer to the appropriate page).

HINT:
  1. When the SRS warning light remains on and the DTC is output (or the normal system code is output), this may be due to a source voltage drop. This malfunction is not stored in memory by the airbag sensor assembly. If the power source voltage returns to normal, the SRS warning light will automatically go off.
  2. When 2 or more codes are indicated, the code with the lower number appears first.
  3. If a code is not listed on the display chart, the airbag sensor assembly may have failed.
  4. 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.
  5. Mark in the check mode column:
    *1: DTC does not apply to check mode.
    *2: DTC applies to check mode.
  6. *3: DTC is only output for vehicles equipped with airbag cut off switch.
  7. *4: DTC is only output for LHD.
  8. *5: DTC is only output for RHD.
