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).

TYPICAL MALFUNCTION THRESHOLDS
INSPECTION PROCEDURE
HINT:
• DTC P2610 is set if an internal ECM problem is detected. Diagnostic procedures are not required.
ECM replacement is required.
• Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition
information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame
data can be helpful in determining whether the vehicle was running or stopped, whether the engine
was warmed up or not, whether the air-fuel ratio was lean or rich, as well as other data recorded at the
time of a malfunction.
(a) Replace the ECM (See page ES-498).
NEXT
(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.

hexagon wrench into the holes to fix the V-ribbed
belt tensioner.
INSPECTION
1. INSPECT V-RIBBED BELT
(a) Visually check the V-ribbed belt for excessive wear,
frayed cords, etc.
If any defect has been found, replace the V-ribbed
belt.
HINT:
Cracks on the rib side of a V-ribbed belt are
considered acceptable.
If the drive belt has chunks missing from its ribs, it
should be replaced.
HINT:
• A "new belt" is a belt which has been used for
less than 5 minutes with the engine running.
• A "used belt" is a belt which has been used for 5
minutes or more with the engine running.
2. INSPECT V-RIBBED BELT TENSIONER ASSEMBLY
(a) Check that nothing gets caught in the tensioner by
turning it clockwise and counterclockwise.
If a malfunction exitsts, replace the tensioner.
