DTC SUMMARY

DESCRIPTION
To ensure the accuracy of the EVAP (Evaporative Emission) monitor values, the soak timer, which is built into the ECM, measures 5 hours (+/- 15 minutes) from when the ignition switch is turned off, before the monitor is run. This allows the fuel to cool down, which stabilizes the Fuel Tank Pressure (FTP). When 5 hours have elapsed, the ECM turns on.

MONITOR DESCRIPTION
5 hours after the ignition switch is turned off, the soak timer activates the ECM to begin the EVAP system monitor. While the engine is running, the ECM monitors the synchronization of the soak timer and the CPU clock. If these two are not synchronized, the ECM interprets this as a malfunction, illuminates the MIL and sets the DTC (2 trip detection logic).

INSPECTION PROCEDURE
HINT:
ECM replacement is required.
1 REPLACE ECM
(a) Replace the ECM (See page ES-498).
2 CHECK WHETHER DTC OUTPUT RECURS
(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch to the ON position.
(c) Clear the DTCs (See page ES-39).
(d) Start the engine and wait for 10 minutes or more.
(e) Select the following menu items on the tester: DIAGNOSIS / ENHANCED OBD II / DTC INFO / PENDING CODES.
(f) If no pending DTC is displayed, the repair has been successfully completed.
OK: No DTC output.
