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

   Standard Resistance

   Front LH side 

   Front RH side 

   Rear LH side 

   Rear RH side 

   Tester Connection (Symbols)	Condition	Specified Condition
   a1-1 (TRG-) - a1-3 (TRG+)	Lock switch not pushed	10 kΩ or higher
   	Lock switch pushed	Below 1 Ω

   Tester Connection (Symbols)	Condition	Specified Condition
   Z1-1 (TRG-) - Z1-3 (TRG+)	Lock switch not pushed	10 kΩ or higher
   	Lock switch pushed	Below 1 Ω

   Tester Connection (Symbols)	Condition	Specified Condition
   c1-1 (TRG-) - c1-3 (TRG+)	Lock switch not pushed	10 kΩ or higher
   	Lock switch pushed	Below 1 Ω

   Tester Connection (Symbols)	Condition	Specified Condition
   b1-1 (TRG-) - b1-3 (TRG+)	Lock switch not pushed	10 kΩ or higher
   	Lock switch pushed	Below 1 Ω

NG → REPLACE OUTSIDE HANDLE ASSEMBLY

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Replace the electrical key oscillator.
2. Check that the entry LOCK/UNLOCK function operates normally.

   OK

   Entry LOCK/UNLOCK function operates normally.

NG → PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE 

OK → END (ELECTRICAL KEY OSCILLATOR IS DEFECTIVE)
