INSPECTION PROCEDURE
HINT:

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

If DTC P1300 is displayed, check ignition coil No.2 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.
1 Check for spark plug and spark of misifining cylinder (See page DI±89).
NG Go to step 4.
OK
2 Check for open and short in harness and connector in IGF signal circuit between
ECM and ignition coils (See page IN±31).
NG Repair or replace harness or connector.
OK

ECM Power Source Circuit
CIRCUIT INSPECTION
When the ignition switch is turned on, battery positive voltage is applied to terminal IGSW of the ECM and
the EFI main relay (Marking: EFI) control circuit in the ECM sends a signal to terminal MREL of the ECM
switching on the EFI main relay.
This signal causes current to flow to the coil, closing the contacts of the EFI, main relay and supplying power
to terminals +B of the ECM.
If the ignition switch is turned off, the ECM continues to switch on the EFI main relay for a maximum of 2
seconds for the initial setting of the IAC valve.
