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

      Connector & terminal 

      Engine type: FB 

      (T31) No. 5 (+) - Chassis ground (-):

      Engine type: FA 

      (T31) No. 6 (+) - Chassis ground (-):

   Is the voltage 10 V or more?

   Yes  : Go to  2.

   No  :

   • Check the fuse.
   • Check for open or short circuit in the harness between inhibitor switch and ECM.
2. CHECK INHIBITOR SWITCH CIRCUIT  .
   1. Turn the ignition switch to OFF.
   2. Disconnect the ECM connector.
   3. Measure the resistance between inhibitor switch connector terminal and ECM connector terminal.

      Connector & terminal 

      Engine type: FB model 

      (T31) No. 5 - (B62) No. 50:

      Engine type: FA model 

      (T31) No. 6 - (E52) No. 27:

   Is the resistance less than 10 Ω?

   Yes  : Go to  3.

   No  : Repair the harness.

3. CHECK INHIBITOR SWITCH  .

   Remove and check the inhibitor switch. Refer to CONTINUOUSLY VARIABLE TRANSMISSION (TR580)>INHIBITOR SWITCH . Refer to CONTINUOUSLY VARIABLE TRANSMISSION (TR690)>Inhibitor Switch .

   Is the check result OK?

   Yes  : Replace the ECM. Refer to FUEL INJECTION (FUEL SYSTEMS) (H4DO)>Engine Control Module (ECM) . Refer to FUEL INJECTION (FUEL SYSTEMS) (H4DOTC)>Engine Control Module (ECM) .

   No  : Replace the inhibitor switch.
