(1) If the room temp, is approx. -20°C (-4°F) of less, DTC B1411/11 maybe output even though the system is normal.
(2) If the ambient temperature is approx. -50°C (-58°F) or less, a DTC maybe output even though the system is normal.
(3) If the check is being performed in a dark place, DTC B1421/21 (solar sensor circuit abnormal) could be displayed. In this case, perform DTC check again while shining a light, such as inspection light, on the solar sensor. If DTC B1421/21 is still displayed, there could be trouble in the solar sensor circuit.
(4) If the check is being performed in a dark place, DTC B1424/24 (solar sensor circuit abnormal) could be displayed. In this case, perform DTC check again while shining a light, such as inspection light, on the solar sensor. If DTC B1424/24 is still displayed, there could be trouble in the solar sensor circuit.
(5) *5 Compressor lock (DTC B1422/22) is indicated only for a current malfunction (See DTC B1422/22 COMPRESSOR LOCK SENSOR CIRCUIT ). To confirm DTC B1422/22, perform the following steps. (1) With the engine ON, enter the DTC check mode. (2) Press the R/F switch to enter actuator check mode, and set the operation to Step No. 3. (3) Press the AUTO switch to return to DTC check mode. (4) The DTC is displayed after approx. 3 secs.
(6) *6 The A/C control assembly memorizes the DTC of the respective malfunction when it occurs for period of time indicated in the brackets.
(7) *7 If the check is being performed in a dark place, DTC B1421/21 (solar sensor circuit abnormal) could be displayed. In this case, perform DTC check again while shining a light, such as inspection light, on the solar sensor. If DTC B1421/21 is still displayed, there could be trouble in the solar sensor circuit.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
