INSPECT EFFECT OF VEHICLE CONDITION FOR MALFUNCTION
•  Verify how the customer drives the vehicle by asking the customer the following:
―  Engine speed is high and remains high for continuous long periods like when climbing a long steep grade.
•  Is the engine generating excessive heat when driven?
Yes
Go to the next step.
No
Go to Step 6.
5
INSPECT FOR MALFUNCTION DUE TO OVERHEATING
Caution
•  While performing this step, always operate the vehicle in a safe and lawful manner.
•  When the M-MDS is used to observe monitor system status while driving, be sure to have another technician with you, or record the data in the M-MDS using the PID/DATA MONITOR AND RECORD capturing function and inspect later.
•  Access the ECT PID using the M-MDS.
•  Is the ECT PID value less than 110 °C {230 °F} while the vehicle is driven on a flat road?
Yes
Explain to the customer that the vehicle is normal.
Go to Step 7.
No
The cause of this concern could be from the cooling system overheating.
•  Perform the symptom troubleshooting “NO.22 COOLING SYSTEM CONCERNS-OVERHEATING”.
