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.

PCS (Pre-Collision
System)
When the radar sensor detects possibility of a frontal collision,
the pre-collision system such as the brakes and seat belts are
automatically engaged to lessen impact as well as vehicle damage.

Inspection
1. INSPECT GARAGE DOOR OPENER
Press the switch and check that each red LED turns
on. If one or more of the switches does not turn on
the LED, confirm normal operation of the fuse and
wire harness, then replace the garage door opener.

Data list / active test
1. READ DATA LIST
HINT:
Using the intelligent tester to read the Data List allows
the values or states of switches, sensors, actuators and
other items to be read without removing any parts. This
non-intrusive inspection can be very useful because
intermittent conditions or signals may be disco ...
