INSPECTION PROCEDURE

NOTICE:

Inspect the fuses for circuits related to this system before performing the following inspection procedure.

1. Enter the "Display Check" mode and select "Vehicle Signal Check Mode" (RAV4_ACA30 RM000003A3N00LX.html).
   

2. Check that the display changes between ON and OFF according to the shift lever operation.
   

   OK:

   Shift Lever Position	Display
   R	ON
   Except R	OFF

   HINT:

   This display is updated once per second. As a result, it is normal for the display to lag behind the actual shift lever operation.

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

   Standard Voltage:

   Tester Connection	Switch Condition	Specified Condition
   E57-5 (REV) - Body ground	Ignition switch ON Shift lever in R	11 to 14 V
   E57-5 (REV) - Body ground	Ignition switch ON Shift lever in any position except R	Below 1 V

1. Check the transaxle type.
   

   Result

   Result	Proceed to
   CVT	A
   Automatic Transaxle	B
   Manual Transaxle	C

1. Disconnect the E57 navigation receiver assembly connector.
   

2. Disconnect the B28 park/neutral position switch connector.
   

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

   Standard Resistance:

   Tester Connection	Condition	Specified Condition
   E57-5 (REV) - B28-2 (RL)	Always	Below 1 Ω
   E57-5 (REV) - Body ground	Always	10 kΩ or higher

1. Disconnect the B28 switch connector.
   

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

   Standard Resistance:

   Tester Connection	Condition	Specified Condition
   1 (RB) - 2 (RL)	Shift lever in R	Below 1 Ω
   1 (RB) - 2 (RL)	Shift lever in P	10 kΩ or higher

1. Disconnect the E57 navigation receiver assembly connector.
   

2. Disconnect the B28 park/neutral position switch connector.
   

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

   Standard Resistance:

   Tester Connection	Condition	Specified Condition
   E57-5 (REV) - B28-2 (RL)	Always	Below 1 Ω
   E57-5 (REV) - Body ground	Always	10 kΩ or higher

1. Disconnect the B28 switch connector.
   

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

   Standard Resistance:

   Tester Connection	Condition	Specified Condition
   1 (RL) - 2 (RB)	Shift lever in R	Below 1 Ω
   1 (RL) - 2 (RB)	Shift lever in P	10 kΩ or higher

   NG (U241E)	C

1. Disconnect the E57 navigation receiver assembly connector.
   

2. Disconnect the B25 switch connector.
   

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

   Standard Resistance:

   Tester Connection	Condition	Specified Condition
   E57-5 (REV) - B25-1	Always	Below 1 Ω
   E57-5 (REV) - Body ground	Always	10 kΩ or higher

1. Disconnect the B25 switch connector.
   

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

   Standard Resistance:

   Tester Connection	Condition	Specified Condition
   1 - 2	Shift lever in R	Below 1 Ω
   1 - 2	Shift lever not in R	10 kΩ or higher
