INSPECTION PROCEDURE

HINT:

1. If DTC U0100 has been stored, troubleshoot the CAN communication system first.
   
2. If there is an open or short in the engine coolant temperature sensor circuit, an SFI system DTC is output. If output, perform troubleshooting on the SFI system.
   

1. Connect the intelligent tester to the DLC3.
   

2. Turn the ignition switch on (IG) and turn the tester ON.
   

3. Perform the ACTIVE TEST according to the prompts displayed on the tester.

   Combination meter

   Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
   Coolant Temperature	Coolant temperature / Min.: 0°C (32°F), Max.: 127.5°C (261.5°F)	After warming up: 80 to 95°C (176 to 203°F)	If the value is "0°C (32°F)" or "127.5°C (261.5°F)", sensor circuits are open or shorted.

   OK:

   Vehicle's coolant temperature and tester value are the same.
