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.
If malfunction code is displayed during the DTC check (sensor check), check the circuit listed for that code in DIAGNOSTIC TROUBLE CODE TABLE . (Proceed to the DTC No. given for that circuit).

HINT:
- *1 : If the room temp. is approx. -18.6°C (-3.7°F) or lower, trouble code 11 may be output even though the system is normal.
- *2 : If the ambient temp. is approx. -52.9°C (-61.4°F) or lower, a malfunction code may be output even though the system is normal.
- *3 : If the check is performed in a dark place, DTC 21, 24 (solar sensor circuit) could be displayed.
- *4
: Compressor lock (DTC 22) is indicated only for a existing malfunction (See DTC 22 COMPRESSOR LOCK SENSOR CIRCUIT
).
To confirm DTC 22, perform the following steps.
- With the engine ON, enter the DTC check mode.
- Press the R/F switch to enter actuator check mode, and set the operation to Step No. 3.
- Press the AUTO switch to return to DTC check mode.
- The DTC is displayed after approx. 3 sec.
- *5 : The A/C amplifier memorizes the DTC of the respective malfunction which occurred within the period of the time indicated in the brackets.
- *6 : Even though the system is in good condition, DTC is output when the seat sensor temperature senses below -40° (-104°F) and over 99°C (210.2°F).
- *7 : DTC 24, 36 and 46 are indicated only for limited grade (right/left independent temperature control system).
