1. CHECK TRANSMISSION TYPE. 

   Is the transmission type CVT?

   Yes:  Go to  2.

   No:  Go to  5. (MT model)

2. CHECK INHIBITOR SWITCH CIRCUIT. 
   1. Turn the ignition switch to OFF.
   2. Disconnect the inhibitor switch harness connector.
   3. Turn the ignition switch to ON.
   4. Measure the voltage between harness connector terminal and chassis ground.

      Connector & terminal 

      (T7) No. 6 (+) - Chassis ground (-):

   Is the voltage 10 V or more?

   Yes:  Go to  3.

   No:  Check for open or short circuit in the harness between inhibitor switch and ECM.

3. CHECK INHIBITOR SWITCH CIRCUIT. 
   1. Turn the ignition switch to OFF.
   2. Disconnect the starter motor harness connector.
   3. Measure the resistance between the inhibitor switch harness connector terminal and the starter motor.

      Connector & terminal 

      (T7) No. 9 - Starter motor:

   Is the resistance less than 10 Ω?

   Yes:  Go to  4.

   No:  Repair the harness.

4. CHECK INHIBITOR SWITCH. 

   Remove and check the inhibitor switch. Refer to CRUISE CONTROL SYSTEM>INHIBITOR SWITCH .

   Is the check result OK?

   Yes:  Replace the ECM.

   Refer to FUEL INJECTION (FUEL SYSTEMS) (EXCEPT FOR STI)>ENGINE CONTROL MODULE (ECM) . Refer to FUEL INJECTION (FUEL SYSTEMS) (STI)>ENGINE CONTROL MODULE (ECM) .

   No:  Replace the inhibitor switch.

5. CHECK NEUTRAL POSITION SWITCH CIRCUIT. 
   1. Turn the ignition switch to OFF.
   2. Disconnect the neutral position switch harness connector.
   3. Turn the ignition switch to ON.
   4. Measure the voltage between harness connector terminal and chassis ground.

      Connector & terminal 

      Engine type: FA 

      (B25) No. 2 (+) - Chassis ground (-):

      Engine type: EJ 

      (T12) No. 1 (+) - Chassis ground (-):

   Is the voltage 10 V or more?

   Yes:  Go to  6.

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

6. CHECK NEUTRAL POSITION SWITCH CIRCUIT. 
   1. Turn the ignition switch to OFF.
   2. Measure resistance between harness connector terminal of neutral position switch and chassis ground.

      Connector & terminal 

      Engine type: FA 

      (B25) No. 1 - Chassis ground:

      Engine type: EJ 

      (T12) No. 2 - Chassis ground:

   Is the resistance less than 10 Ω?

   Yes:  Go to  7.

   No:  Repair the harness.

7. CHECK NEUTRAL POSITION SWITCH. 

   Remove and check the neutral position switch. Refer to CRUISE CONTROL SYSTEM>NEUTRAL POSITION SWITCH .

   Is the check result OK?

   Yes:  Replace the ECM.

   Refer to FUEL INJECTION (FUEL SYSTEMS) (EXCEPT FOR STI)>ENGINE CONTROL MODULE (ECM) . Refer to FUEL INJECTION (FUEL SYSTEMS) (STI)>ENGINE CONTROL MODULE (ECM) .

   No:  Replace the neutral position switch.
