Reverse Signal Circuit (FROM 12/2010): Procedure

1. Disconnect the N9 connector from the inner rear view mirror assembly.
2. Measure the voltage according to the value(s) in the table below.

   Standard Voltage

   Tester Connection	Condition	Specified Condition
   N9-3 (REV) - Body ground	Ignition switch ON, shift lever in R	7 V or higher

NG → See step   2 

OK → See step   4 

1. Disconnect the N9 connector from the inner rear view mirror assembly.
2. Disconnect the B13 connector from the park/neutral position switch assembly.
3. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   N9-3 (REV) - B13-2 (RL)	Always	Below 1 Ω
   N9-3 (REV) - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Disconnect the B13 connector from the park/neutral position switch assembly.
2. Measure the resistance according to the value(s) in the table below.
