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

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   J29-1 (GND) - Body ground	Always	Below 1 Ω
   J29-2 (SGND) - Body ground	Always	Below 1 Ω

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

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

   Standard Voltage

   Tester Connection	Condition	Specified Condition
   J29-7 (B) - J29-1 (GND)	Always	10 to 14 V
   J29-7 (B) - J29-2 (SGND)	Always	10 to 14 V

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR (STEERING LOCK ACTUATOR ASSEMBLY - BATTERY) 

OK → See step   3
