1. PERFORM REAL TIME DIAGNOSIS  .

   Check the input signal of cruise control system. Ref. to EYESIGHT (DIAGNOSTICS)>REAL-TIME DIAGNOSIS 

   Is the check result OK?

   Yes  : Currently, it is normal. Finish the diagnosis.

   No  : Go to  2.

2. CHECK INHIBITOR SWITCH CIRCUIT  .
   1. Turn the ignition switch to OFF.
   2. Disconnect the connector from inhibitor switch.
   3. Turn the ignition switch to ON.
   4. Using a tester, measure the voltage between inhibitor switch connector and chassis ground.

      Connector & terminal 

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

   Is the voltage 10 V or more?

   Yes  : Go to  3.

   No  :

   • Check the fuse. Ref. to WIRING SYSTEM>STARTER SYSTEM>WIRING DIAGRAM
   • 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 connector from ECM.
   3. Using a tester, measure the resistance between the inhibitor switch connector and the ECM connector.

      Connector & terminal 

      (T31) No. 6 - (E52) No. 12:

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

   Is the check result OK?

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

   No  : Replace the inhibitor switch. Ref. to CONTINUOUSLY VARIABLE TRANSMISSION (TR690)>INHIBITOR SWITCH
