WIRING DIAGRAM

INSPECTION PROCEDURE

1. Using the intelligent tester, read the Data List (HILUX_TGN26 RM000000PM306GX.html).
   
   

   Cruise Control

   Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
   CCS Main SW M-CPU	Cruise control main switch signal (Main CPU) / ON or OFF	ON: Cruise control main switch (Main CPU) on OFF: Cruise control main switch (Main CPU) off	-
   Cancel Switch	CANCEL switch signal / ON or OFF	ON: CANCEL switch on OFF: CANCEL switch off	-
   SET/COAST Switch	SET / COAST switch signal / ON or OFF	ON: -SET switch on OFF: -SET switch off	-
   RES/ACC Switch	RES / ACC switch signal / ON or OFF	ON: +RES switch on OFF: +RES switch off	-

   OK:

   The display is as specified in the normal condition column.
   

1. Remove the cruise control main switch (HILUX_TGN26 RM000000VQ3069X.html).
   

   
   
   
   

2. Measure the resistance according to the value(s) in the table below.
   

   Standard Resistance:

   Tester Connection	Switch Condition	Specified Condition
   3 (CCS) - 1 (ECC)	Cruise control main switch on	Below 2.5 Ω
   	Cruise control main switch off	1 MΩ or higher
   	+RES switch held on	235 to 245 Ω
   	-SET switch held on	617 to 643 Ω
   	CANCEL switch held on	1509 to 1571 Ω

1. Remove the cruise control switch wire.
   

2. Measure the resistance according to the value(s) in the table below.
   

   Standard Resistance:

   Tester Connection	Condition	Specified Condition
   A-3 (CCS) - B-3 (CCS)	Always	Below 1 Ω
   A-1 (ECC) - B-4 (ECC)

1. Remove the spiral cable (HILUX_TGN26 RM0000010B200SX.html).
   

2. If there are any defects as follows, replace the spiral cable with a new one: scratches, cracks, dents or chips on the connector or spiral cable.
   

3. Check the spiral cable.
   

   1. Set the spiral cable to the center position (HILUX_TGN26 RM0000010AZ00SX.html).
      

   2. Rotate the spiral cable 2.5 times clockwise and measure the resistance according to the value(s) in the table below. Then rotate the spiral cable 5 times counterclockwise and measure the resistance according to the value(s) in the table below.
      

      NOTICE:

      As the spiral cable may break, do not rotate the spiral cable more than the specified amount.

      Standard Resistance:

      Tester Connection	Condition	Specified Condition
      A-1 (CCS) - B-3 (CCS)	Always	Below 1 Ω
      A-2 (ECC) - B-4 (ECC)

   3. Set the spiral cable to the center position and rotate the spiral cable 2.5 times clockwise. Then, while rotating the spiral cable 5 times counterclockwise, measure the resistance according to the value(s) in the table below.
      

      Standard Resistance:

      Tester Connection	Condition	Specified Condition
      A-1 (CCS) - B-3 (CCS)	Always	Below 1 Ω
      A-2 (ECC) - B-4 (ECC)

1. Disconnect the G12 spiral cable connector.
   

2. Disconnect the G39 ECM connector.
   

3. Measure the resistance according to the value(s) in the table below.
   

   Standard Resistance:

   Tester Connection	Condition	Specified Condition
   G12-1 (CCS) - G39-21 (CCS)	Always	Below 1 Ω
   G12-2 (ECC) - Body ground
   G12-1 (CCS) - Body ground	Always	10 kΩ or higher
