Reverse Signal Circuit [08/2015 - ]: Procedure

1. Disconnect the I8 navigation receiver assembly connector.
2. Measure the voltage according to the value(s) in the table below.

   Standard Voltage

   Tester Connection	Condition	Specified Condition
   I8-2 (REV) - Body ground	Ignition switch ON Shift lever in R	11 to 14 V
   I8-2 (REV) - Body ground	Ignition switch ON Shift lever in any position other than R	Below 1 V

NG → See step   2 

OK → See step   4 

1. Disconnect the I8 navigation receiver assembly connector.
2. Disconnect the E4 park/neutral position switch assembly connector.
3. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   I8-2 (REV) - E4-2 (RL)	Always	Below 1 Ω
   I8-2 (REV) - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Disconnect the E4 park/neutral position switch assembly connector.
2. Measure the voltage according to the value(s) in the table below.

   Standard Voltage

   Tester Connection	Condition	Specified Condition
   E4-1 (RB) - Body ground	Ignition switch ON	11 to 14 V
