Diagnostic Trouble Code Table

WARNING: This page is about a different car, the 2006 Toyota 4Runner. However, it is still accessible from the selected car via links, so may be relevant.

DTCS FOR SUPPLEMENTAL RESTRAINT SYSTEM

If a trouble code is displayed during the DTC check, check the circuit listed for the code in DTC TABLE .

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 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 table, 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:
"O": DTC is corresponding to the check mode.

"-": DTC is not corresponding to the check mode.
When DTC B1150/23 is detected as a result of troubleshooting for the Supplemental Restraint System, perform troubleshooting for the occupant classification system as shown in DTC TABLE .

DTCS FOR FRONT PASSENGER OCCUPANT CLASSIFICATION SYSTEM

HINT:

Use the hand-held tester to check the DTC of the occupant classification ECU, otherwise the DTC cannot be read.
When DTC B1150/23 is detected as a result of troubleshooting for the Supplemental Restraint System, perform troubleshooting for the occupation classification system as shown in DTC TABLE .
