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

   Tester Connection	Condition	Specified Condition
   2 (RB) - 6 (PL)	Shift lever in P	Below 1 Ω
   2 (RB) - 6 (PL)	Shift lever not in P	10 kΩ or higher

NG → See step   6 

OK: Go to next step 

1. Disconnect the d1*1 or c1*2 ECU connector.
   • *1: for LH Side
   • *2: for RH Side
2. Disconnect the C33 switch connector.
3. Measure the resistance according to the value(s) in the table below.
   STANDARD RESISTANCE FOR LH SIDE
   
   

   Tester Connection	Condition	Specified Condition
   d1-6 (P) - C33-6 (PL)	Always	Below 1 Ω
   d1-6 (P) - Body ground	Always	10 kΩ or higher

   STANDARD RESISTANCE FOR RH SIDE
   
   

   Tester Connection	Condition	Specified Condition
   c1-6 (P) - C33-6 (PL)	Always	Below 1 Ω
   c1-6 (P) - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK → See step   7
