Inspection Procedure

HINT:

• If DTC P1300 is displayed, check No.1 ignition coil with igniter circuit.

• If DTC P1305 is displayed, check No.2 ignition coil with igniter circuit.

• If DTC P1310 is displayed, check No.3 ignition coil with igniter circuit.

• If DTC P1315 is displayed, check No.4 ignition coil with igniter circuit.

• Read freeze frame data using TOYOTA hand-held tester or OBD II scan tool. Because freeze frame records the engine conditions when the malfunction is detected, when troubleshooting it is useful for determining whether the vehicle was running or stopped, the engine warmed up or not, the air-fuel ratio lean or rich, etc. at the time of the malfunction.
