P2610 ECM INTERNAL TIMER

Description

INFOID:0000000011278169

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.

ECM/PCM INTERNAL ENG OFF TIMER
(ECM/PCM internal engine off timer perfor-
mance)

• ECM internal engine off timer is malfunctioning.
• The time calculated by ECM based on a descent allowance of engine 

coolant temperatures during ignition switch OFF is extremely shorter 
than the time counted by the Engine internal OFF timer.

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-457, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000011278171

1.

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-69, "CONSULT Function"

.

NO

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE

1. Erase DTC.

2. Perform DTC Confirmation Procedure again. Refer to  

EC-456, "DTC Description"

.

Is the 1st trip DTC P2610 displayed again?

YES

>> Replace ECM. Refer to 

EC-502, "Removal and Installation"

.

NO

>> INSPECTION END
