SUPPLEMENTAL RESTRAINT SYSTEMS: AIRBAG SYSTEM: DIAGNOSTIC TROUBLE CODE CHART; 2016 - 2020 MY Sienna [12/2015

DIAGNOSTIC TROUBLE CODE CHART

If a DTC is displayed during the DTC check, check the circuit listed for the DTC in the table below. Refer to the appropriate reference listed for that circuit.

HINT:

When the SRS warning light remains on and the normal system code is output, a decrease in the source voltage is likely to occur. This malfunction is not stored in the memory of the center airbag sensor assembly. If the power source voltage returns to normal, the SRS warning light will automatically go off.
When 2 or more DTCs are indicated, the DTC with the lowest number appears first.
If a DTC is not listed on the DTC chart, the center airbag sensor assembly may have malfunctioned.
In the case of any malfunctions concerning open circuits, shorts to ground, or shorts to B+ due to squibs, other DTCs may not be stored. In this case, repair the malfunction currently indicated and then perform the malfunction diagnosis again.
Mark in the check mode column:
*1: DTC does not correspond to check mode.

*2: DTC corresponds to check mode.
