DESCRIPTION

УКАЗАНИЕ:

To allow use of the intelligent tester to inspect the push-button start function when the engine switch is off, repeat opening and closing any of the doors. Opening and closing a door establishes communication between the intelligent tester and the main body ECU. (Opening and closing a door can also be simulated by operating a door courtesy light switch.)

WIRING DIAGRAM

INSPECTION PROCEDURE

1. Inspect entry detection area.
   

   1. When the electrical key is in either of the 2 inspection points in the illustration, the clutch pedal is depressed, check that the engine switch indicator illuminates in green.
      

      OK:

      Engine switch illuminates in green.
      

      УКАЗАНИЕ:

      If the engine switch does not illuminate, perform troubleshooting according to PROBLEM SYMPTOMS TABLE (See page Нажмите здесь).

1. Remove the AM2 NO. 2 fuse from the engine room junction block.
   

2. Measure the resistance of the fuse.
   

   Standard resistance:

   Below 1 Ω
   

1. Check that the connectors are securely connected and the terminals are not deformed or loose.
   

   OK:

   The connectors are securely connected and the terminals are not deformed or loose.
   

1. Disconnect the E50 and E51 ECU connectors.
   

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

   Standard voltage:

   Tester Connection	Condition	Specified Condition
   E51-1 (AM1) - Body ground	Always	11 to 14 V
   E50-6 (AM2) - Body ground	Always	11 to 14 V

1. Disconnect the E51 ECU connector.
   

   
   
   
   

2. Disconnect the 2E junction block connector.
   

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

   Standard resistance:

   Tester Connection	Condition	Specified Condition
   2E-17 (GND1) - Body ground	Always	Below 1 Ω
   E51-4 (GND2) - Body ground	Always	Below 1 Ω

1. Delete the DTCs (See page Нажмите здесь).
   

   УКАЗАНИЕ:

   After all the DTCs are cleared, check if the trouble occurs again 5 seconds after the engine switch is turned on (IG).

2. Check for DTCs again.
   

   OK:

   No DTC is output.
   

1. Connect the intelligent tester to the DLC3.
   

2. Turn the engine switch on (IG).
   

3. Check the DATA LIST for proper functioning of the start switches 1 and 2.
   

   УКАЗАНИЕ:

   When using the intelligent tester with the engine switch off, turn on and off any of the door courtesy light switches repeatedly at 1.5 second intervals or less until communication between the tester and vehicle starts.

   
   

   Body:

   Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
   St SW1	Start Switch 1/ON or OFF	ON: Engine switch is pushed OFF: Engine switch is not pushed	-
   St SW2	Start Switch 2/ON or OFF	ON: Engine switch is pushed OFF: Engine switch is not pushed	-

   OK:

   ON (engine switch is pushed) and OFF (engine switch is not pushed) appear on the screen.
   

1. Remove the engine switch (for sedan: See page Нажмите здесь).
   

   
   
   
   

2. Remove the engine switch (for hatchback: See page Нажмите здесь).
   

3. Measure the resistance of the switch.
   

   Standard resistance:

   Tester Connection	Switch Condition	Specified Condition
   7 (SS1) - 5 (GND)	Pushed	Below 1 Ω
   2 (SS2) - 5 (GND)	Pushed	Below 1 Ω
   7 (SS1) - 5 (GND)	Not pushed	10 kΩ or higher
   2 (SS2) - 5 (GND)	Not pushed	10 kΩ or higher

4. Proceed to the next step based on the inspection result.
   

   Result:

   Result	Proceed to
   OK	A
   NG (for sedan)	B
   NG (for hatchback)	C

1. Disconnect the E51 ECU connector.
   

   
   
   
   

2. Disconnect the E38 switch connector.
   

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

   Standard resistance:

   Tester Connection	Condition	Specified Condition
   E38-7 (SS1) - E51-10 (SSW1)	Always	Below 1 Ω
   E38-2 (SS2) - E51-9 (SSW2)	Always	Below 1 Ω
   E38-5 (GND) - Body ground	Always	Below 1 Ω
   E38-7 (SS1) or E51-10 (SSW1) - Body ground	Always	10 kΩ or higher
   E38-2 (SS2) or E51-9 (SSW2) - Body ground	Always	10 kΩ or higher
