INSPECTION PROCEDURE
Tech Tips
-
If DTC P0A1A-151, P0A1A-155, P0A1A-658, P0A1A-659, P0A1A-791, P0A1B-163, P0A1B-164, P0A1B-192, P0A1B-511, P0A1B-512, P0A1B-661, P0A1B-786 or P0A1B-794 is output, clear the DTCs, perform the following procedure, and check that the same DTC is not output after the repair.
-
Turn the power switch on (IG) and wait for 5 seconds or more.
-
If DTC P0A1A-156 or P0A1B-193 is output, clear the DTCs, perform the following procedure, and check that the same DTC is not output after the repair.
-
Turn the power switch on (IG) and wait for 1 minute or more.
-
If DTC P0A1A-166 is output, clear the DTCs, perform the following procedure, and check that the same DTC is not output after the repair.
-
Turn the power switch on (READY).
-
With the vehicle stopped and the shift lever in P, depress the accelerator pedal and start the engine.
-
Depress the accelerator pedal and keep the engine running for 30 seconds or more.
-
If DTC P0A1B-198 is output, clear the DTCs, perform the following procedure, and check that the same DTC is not output after the repair.
-
