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

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   3 (IG) - 7 (S)	Shift lever in S, "+" or "-"	Below 1 Ω
   	Shift lever in any position other than S, "+" or "-"	10 kΩ or higher

3. Reconnect the transmission control switch connector.

NG → See step   9 

OK → REPAIR OR REPLACE HARNESS OR CONNECTOR (ECM - TRANSMISSION CONTROL SWITCH) 

1. Disconnect the park/neutral position switch assembly connector.

2. Turn the ignition switch to ON.
3. Measure the voltage according to the value(s) in the table below.

   Standard Voltage

   Tester Connection	Switch Condition	Specified Condition
   B5-1 (RB) - Body ground	Ignition switch ON	11 to 14 V

4. Reconnect the park/neutral position switch assembly connector.

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR (PARK/NEUTRAL POSITION SWITCH ASSEMBLY - BATTERY) 

OK: Go to next step 

1. Inspect the park/neutral position switch assembly, refer to INSPECTION .

NG → See step   10 

OK: Go to next step 

1. Turn the ignition switch to ON.
2. Measure the voltage according to the value(s) in the table below.

   Standard Voltage

   Tester Connection	Condition	Specified Condition
   B50-28 (P) - Body ground	Ignition switch ON Shift lever in P	11 to 14 V
   	Ignition switch ON Shift lever in any position other than P	0 to 1.5 V
   B50-27 (R) - Body ground	Ignition switch ON Shift lever in R	11 to 14 V
   	Ignition switch ON Shift lever in any position other than R	0 to 1.5 V
   B50-26 (N) - Body ground	Ignition switch ON Shift lever in N	11 to 14 V
   	Ignition switch ON Shift lever in any position other than N	0 to 1.5 V
   B50-30 (D) - Body ground	Ignition switch ON Shift lever in D	11 to 14 V
   	Ignition switch ON Shift lever in any position other than D	0 to 1.5 V

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR (ECM - PARK/NEUTRAL POSITION SWITCH ASSEMBLY) 

OK: Go to next step 

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

   Standard Resistance (Check for Open)

   Tester Connection	Condition	Specified Condition
   B5-4 (B) - B51-24 (NSW)	Always	Below 1 Ω

   Standard Resistance (Check for Short)

   Tester Connection	Condition	Specified Condition
   B5-4 (B) or B51-24 (NSW) - Body ground	Always	10 kΩ or higher

4. Reconnect the ECM connector.
5. Reconnect the park/neutral position switch assembly connector.

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR (PARK/NEUTRAL POSITION SWITCH ASSEMBLY - ECM) 

OK → See step   11
