Toyota Sienna Service Manual: Diagnostic trouble code chart
1. DTCS FOR AIRBAG SYSTEM
If a malfunction code is displayed during the DTC check, check the circuit listed for the code in the table below (Proceed to the page 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 memory by the center airbag sensor assembly. If 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 is not listed on the display chart, the center airbag sensor assembly 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.
- When DTC B1150/23 is detected as a result of troubleshooting for the Airbag System, perform troubleshooting for the Occupant Classification System as shown in the chart below.
- Mark in the check mode column:
*1: DTC is not corresponding to the check mode.
*2: DTC is corresponding to the check mode. - DTC which has the mark of the *3 is output only the equipped car of side airbag.
