P2610 ECM INTERNAL TIMER

Description

INFOID:0000000012198702

This ECM contains a timer and measures time between an ignition switch OFF and the next ignition switch

ON. This enables the judging of the state of engine cooling at an engine start.

PERFORM DTC CONFIRMATION PROCEDURE-II

CAUTION:

To start this self-diagnosis, the conditions listed bellow are required to be satisfied. Perform the fol-

lowing steps to satisfy the conditions.

• Engine coolant temperature decrease by 55

°C (131°F) or more during the time between an ignition

switch OFF (after engine warm-up) and the second ignition switch ON.

• A fuel temperature at the second ignition switch ON is

−5°C (23°F) or more and less than 35°C (95°F).

• The temperature difference between engine coolant and fuel is 5

°C (41°F) or more.

NOTE:

This self-diagnosis is not performed if the distance traveled is extremely short.

1. Turn ignition switch ON.

2. Start engine and warm it up to normal operating temperature.

3. Turn ignition switch OFF and soak the vehicle for at least 12 hours.

CAUTION:

• Never turn ON the ignition switch during soaking.

• Never open the fuel filler cap and perform refueling during soaking.

4. Turn ignition switch ON and wait at least 190 seconds.

5. Check 1st trip DTC.
Is 1st trip DTC detected?

YES

>> Proceed to

EC-1178, "Diagnosis Procedure"

>> INSPECTION END

Diagnosis Procedure

Is the inspection result normal?

YES

>> GO TO 2.

>> Repair or replace error-detected parts.

CHECK SELF-DIAGNOSTIC RESULT

Check that DTCs related to the fuel system and the cooling system are not detected.
Is the inspection result normal?

YES

>> Check the DTC. Refer to

EC-706, "DTC Index"

>> GO TO 3.

PERFORM DTC CONFIRMATION PROCEDURE

1. Erase DTC.

2. Perform DTC Confirmation Procedure again. Refer to

EC-1177, "DTC Logic"

Is the 1st trip DTC P2610 displayed again?

YES

>> Replace ECM. Refer to

EC-1256, "Removal and Installation"
