2. Disconnect the ECM connectors.
3. Turn the ignition switch to ON, and measure the voltage according to the value(s) in the table below when the shift lever is moved to each position.

   Standard Voltage

   Tester Connection	Shift Position	Specified Condition
   B29-77 (P) - Body ground	P	11 to 14 V
   	Except P	Below 1 V
   B29-99 (N) - Body ground	N	11 to 14 V
   	Except N	Below 1 V
   B29-76 (R) - Body ground	R	11 to 14 V*
   	Except R	Below 1 V
   A37-47 (D) - Body ground	D and 3	11 to 14 V
   	Except D and 3	Below 1 V
   B29-39 (2) - Body ground	2	11 to 14 V
   	Except 2	Below 1 V
   A37-26 (L) - Body ground	L	11 to 14 V
   	Except L	Below 1 V

   HINT: 

   ^* : The voltage will drop slightly due to lighting up of the back up light.

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Disconnect the transmission control switch connector of shift lock control unit assembly.
