1. CHECK NEUTRAL POSITION SWITCH CIRCUIT  .
   1. Turn the ignition switch to OFF.
   2. Disconnect the neutral position switch connector. Ref. to MANUAL TRANSMISSION AND DIFFERENTIAL (TY75)>SWITCHES AND HARNESS .
   3. Turn the ignition switch to ON.
   4. Measure the voltage between neutral position switch connector and chassis ground.

   Connector & terminal 

   (T44) No. 2 (+) - Chassis ground (-):

   Is the voltage 10 V or more?

   Yes:  Go to  2.

   No:  Check for open or short in the harness between neutral position switch and ECM.

2. CHECK NEUTRAL POSITION SWITCH CIRCUIT  .
   1. Turn the ignition switch to OFF.
   2. Disconnect the ECM connector. Ref. to FUEL INJECTION (FUEL SYSTEMS) (H4DOTC)>ENGINE CONTROL MODULE (ECM) .
   3. Measure the resistance between neutral position switch connector and ECM connector.

   Connector & terminal 

   (T44) No. 1 - (E52) No. 13:

   Is the resistance less than 10 Ω?

   Yes:  Go to  3.

   No:  Repair the harness.

3. PERFORM UNIT INSPECTION OF NEUTRAL POSITION SWITCH  .

   Remove and check the neutral position switch. Ref. to MANUAL TRANSMISSION AND DIFFERENTIAL (TY75)>SWITCHES AND HARNESS>INSPECTION .

   Is the check result OK?

   Yes:  Replace the ECM. Ref. to FUEL INJECTION (FUEL SYSTEMS) (H4DOTC)>ENGINE CONTROL MODULE (ECM) .

   No:  Replace the neutral position switch. Ref. to MANUAL TRANSMISSION AND DIFFERENTIAL (TY75)>SWITCHES AND HARNESS .
