Manual Extract -Actions for Non-Reoccurring Malfunctions

In cases where the malfunction does not reoccur, perform the actions below to determine the cause of the
malfunction.

-Verify that there is no DTC stored in the memory.
-Conduct a reoccurrence test in “Reoccurrence” mode based on the questionnaire. Use the data (ECU voltage
value, etc.) to determine the cause of the malfunction.
-Assume that an electrical system wiring harness or connector is the cause of the
malfunction. Shake these components by hand to verify whether or not a malfunction
occurs and a DTC is generated.
-Assume that an electrical system female connector terminal is the cause of the
malfunction. Verify that the connection points are not defective.
-Heat the accelerator pedal position sensor and other electrical components with
a hair dryer. Verify whether or not the voltage value (resistance value) changes.

-Verify whether or not malfunction symptoms occur under heavy engine loads (headlights, A/C, wiper
switches ON, etc.)
If any aftermarket electrical products have been installed, remove the products and verify that the malfunction
symptoms do not occur.
