13A-DIAGNOSTIC TROUBLE CODE CHART

DIAGNOSTIC TROUBLE CODE CHART

warning

When touching the throttle valve, surely shut off the driving circuits of the throttle valve. In the event that the throttle valve is operated, a finger might be injured as the result of being caught by the throttle valve.

caution

During diagnosis, a DTC associated with other system may be set when the power supply mode of the electric motor switch is turned on with connector(s) disconnected. On completion, confirm all systems for DTC(s). If DTC(s) are set, erase them all.

note	If the diagnostic trouble code (DTC) of the PHEV-ECU had been erased, the DTC of the engine control module (ECM) had also been erased at the same time.

note	Do not replace the engine control module (ECM) until a through terminal check reveals there are no short/open circuits.

note	Check that the ECM ground circuit is normal before checking for the cause of the problem.

note	After the ECM detects a malfunction, a diagnostic trouble code is recorded the next time the electric motor unit is started and the same malfunction is re-detected. However, for items marked with a "^*1", the diagnostic trouble code is recorded on the first detection of the malfunction.

note	The codes marked with a "^*2" in the diagnostic trouble code number column have the following two conditions for recording the diagnostic trouble code.

In case that the misfire causing the damaged catalyst is detected, the diagnostic trouble code is recorded at the time.
In case that the misfire deteriorating the exhaust gas is detected, the diagnostic trouble code is recorded when the same malfunction is redetected after the next engine start.

note

When the refuel control mode cannot be canceled even if fuel filler lid is closed^*3, it can be canceled the refuel control mode by performing the following operations.
*3: The related refuel indication on the combination meter does not disappear, the fuel tank solenoid valve does not turn off, or the power of the ECM does not turn off even if the fuel filler lid is closed.

Using scan tool (M.U.T.-IIISE), "Forced Refuel control completion" from Special Function screen is executed.
30 minutes passed after the item execution.
Drive the vehicle continuously for about 30 seconds.
