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.)

INSPECTION PROCEDURE

1. Remove the AM2 NO. 2 and IG2 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 2E junction block connector.
   

   
   
   
   

2. 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. Disconnect the 1A engine room junction block connector.
   

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

   Standard voltage:

   Tester Connection	Condition	Specified Condition
   1A-4 - Body ground	When battery voltage is not applied to terminals 1A-2 and 1A-3	Below 1 V
   1A-4 - Body ground	When battery voltage is applied to terminals 1A-2 and 1A-3	11 to 14 V

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

   
   
   
   

   Standard resistance:

   Tester Connection	Condition	Specified Condition
   1A-2 - E51-5 (IG2D)	Always	Below 1 Ω
   1A-3 - Body ground		Below 1 Ω
   E51-5 (IG2D) - Body ground		10 kΩ or higher

1. Remove the IG1 relay from the instrument panel junction block.
   

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

   Standard resistance:

   Tester Connection	Condition	Specified Condition
   3 - 5	When battery voltage is not applied to terminals 1 and 2	10 kΩ or higher
   3 - 5	When battery voltage is applied to terminals 1 and 2	Below 1 Ω

1. Disconnect the 2F junction block connector.
   

   
   
   
   

2. Disconnect the E51 ECU connector.
   

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

   Standard resistance:

   Tester Connection	Condition	Specified Condition
   2F-3 - E51-6 (IG1D)	Always	Below 1 Ω
   E51-6 (IG1D) - Body ground	Always	10 kΩ or higher

1. Disconnect the 2G junction block connector.
   

2. 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

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

   Standard voltage:

   Tester Connection	Condition	Specified Condition
   2G-1 - Body ground	Always	11 to 14 V
