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 and 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 and 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. Ref. to CONTINUOUSLY VARIABLE TRANSMISSION (TR580)>INHIBITOR SWITCH . Ref. to CONTINUOUSLY VARIABLE TRANSMISSION (TR690)>INHIBITOR SWITCH .

   Is the check result OK?

   Yes  : Replace the ECM. Ref. to FUEL INJECTION (FUEL SYSTEMS) (H4DO)>ENGINE CONTROL MODULE (ECM) . Ref. to FUEL INJECTION (FUEL SYSTEMS) (H4DOTC)>ENGINE CONTROL MODULE (ECM) .

   No  : Replace the inhibitor switch.
