Inspection Procedure

HINT:

• If DTC U0100 has been stored, troubleshoot the CAN communication system first.
• 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. PERFORM ACTIVE TEST USING TECHSTREAM (COOLANT TEMP) 
   1. Connect Techstream to the DLC3.
   2. Turn the ignition switch on (IG) and turn the tester ON.
   3. Operate the Techstream according to the display and select "ACTIVE TEST" (See DATA LIST / ACTIVE TEST  ).

      Item	Test Details	Diagnostic Note
      Water Temperature Meter Operation	LOW / NORMAL / HIGH	Value selected during Active Test is displayed

      OK: 

      Value selected during "ACTIVE TEST" is displayed. 

   NG : REPLACE COMBINATION METER ASSEMBLY  (See REMOVAL  ).

   OK: Go to next step 

2. READ VALUE USING TECHSTREAM (COOLANT TEMP) 
   1. Connect Techstream to the DLC3.
   2. Turn the ignition switch on (IG) and the tester on
   3. Operate the Techstream according to the display and select "DATA LIST" (See DATA LIST / ACTIVE TEST  ).

      Item	Measurement Item / Range	Normal Condition	Diagnostic Note
      Coolant Temperature	Engine coolant temperature Min.. 0 (0) Max.: 127.5 (261.5)	After warning up 75 to 105 (167 to 221)	Unit: °C (°F)

      OK: 

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