Inspection Procedure

HINT:

In case of using the hand-held tester, start the inspection from 1 and in case of not using the hand-held tester, start from step  2.

1. Read value on hand-held tester. 

   PREPARATION: 

   1. Connect the hand-held tester to the DLC3.
   2. Turn the ignition switch to the ON position and turn the hand-held tester main switch on.
   3. Select the item below in the "DATA LIST", and read the display on the hand-held tester.

   CHECK: 

   Check that the CRUISE main indicator light comes on when the cruise main switch is ON, and go off when the cruise main switch is OFF.

   CCS (ECM): 

   CCS (ECM) INDICATOR
   
   

   Item	Measurement Item/Display (Range)	Normal Condition	Diagnostic Note
   CCS INDICATOR	Cruise indicator signal (Main CPU)/ON or OFF	ON: "CRUISE main indicator" ON OFF: "CRUISE main indicator" OFF	-
   CCS INDICATOR S	Cruise indicator signal (Sub CPU)/ON or OFF	ON: "CRUISE main indicator" ON OFF: "CRUISE main indicator" OFF	-

   OK: 

   When the cruise control main switch is operated, the normal conditions listed above are shown on the display. 

   1. NG : Go to step 2. 
   2. OK : Proceed to next circuit inspection shown in  PROBLEM SYMPTOMS TABLE   . 
2. Check combination meter assy. 

   CHECK: 

   1. Check if other functions in the combination meter (speedometer, indicator, etc.) operate normally.

   OK: 

   Functions operate normally. 

   1. NG : Go to combination meter system (See  CIRCUIT  ). 
   2. OK : Go to next step. 
3. Check harness and connector (Combination meter assy - ECM) 

   PREPARATION: 

   Disconnect the combination meter and ECM connectors.

   CHECK: 

   Measure the resistance according to the value(s) in COMBINATION METER ASSY - ECM  .

   OK: 

   COMBINATION METER ASSY - ECM
   
   

   Tester Connection (Symbol)	Condition	Specified condition
   C11-3 - E4-18 (PI)	Always	Below 1 Ω
   C11-3 - Body ground	Always	10 kBelow 1 Ω or higher
