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 INTELLIGENT TESTER OR TECHSTREAM (COOLANT TEMP) 
   1. Connect an intelligent tester or a Techstream to the DLC3.
   2. Turn the ignition switch on (IG) and turn the tester on.
   3. Operate the intelligent tester or Techstream according to the display and select "ACTIVE TEST" or "Active Test" (See DATA LIST / ACTIVE TEST  ).
      1. Intelligent tester

         Body / Combination Meter / ACTIVE TEST: 

         BODY / COMBINATION METER / ACTIVE TEST
         
         

         Item	Test Details	Diagnostic Note
         COOLANT TEMP	LOW / NORMAL / HIGH	Value selected during ACTIVE TEST is displayed

      2. Techstream

         Body Electrical / Combination Meter / Active Test: 

         BODY ELECTRICAL / COMBINATION METER / 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" or "Active Test" is displayed. 

   NG : REPLACE COMBINATION METER ASSEMBLY  (See REMOVAL  ).

   OK: Go to next step 

2. READ VALUE USING INTELLIGENT TESTER OR TECHSTREAM (COOLANT TEMP) 
   1. Connect an intelligent tester or a Techstream to the DLC3
   2. Turn the ignition switch on (IG) and the tester on
   3. Operate the intelligent tester or Techstream according to the display and select "DATA LIST" or "Data List" (See DATA LIST / ACTIVE TEST  ).
      1. Intelligent tester

         Body / Combination Meter / DATA LIST: 

         BODY / COMBINATION METER / DATA LIST
         
         

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

      2. Techstream

         Body Electrical / Combination meter / Data List: 

         BODY ELECTRICAL / COMBINATION METER / DATA LIST
         
         

         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. 

   NG : REPLACE COMBINATION METER ASSEMBLY  (See REMOVAL  )

   OK: Go TO  SFI SYSTEM
