1. Replace the DOR radiator.






CAUTION: To prevent damage to scan tool MB991958, always turn the ignition switch to the "LOCK" (OFF) position before connecting or disconnecting scan tool MB991958.

2. Connect scan tool MB991958 to the data link connector.
3. Turn the ignition switch to the "ON" position.
4. Read the DTC.
5. Turn the ignition switch to the "LOCK" (OFF) position.

Q: Is DTC P2567 set?

YES : Replace the ECM. When the ECM is replaced, register the ID code. Refer to ID Code Registration Judgment Table [Vehicles with KOS] or ID Code Registration Judgment Table [Vehicles with WCM]. Then go to Step 2.

NO : It can be assumed that this malfunction is intermittent. Refer to General (Body and Chassis), How to Use Troubleshooting/Inspection Service Points-How to Cope with Intermittent Malfunctions.

STEP 2. Using scan tool MB991958, read the diagnostic trouble code (DTC).

1. Turn the ignition switch to the "ON" position.
2. Read the DTC.
3. Turn the ignition switch to the "LOCK" (OFF) position.

Q: Is DTC P2567 set?

YES : Repeat the troubleshooting.

NO : The procedure is complete.
