1. CHECK CRUISE CONTROL COMMAND SWITCH CIRCUIT  .
   1. Remove the driver's airbag module. Ref. to AIRBAG SYSTEM>DRIVER'S AIRBAG MODULE> REMOVAL .
   2. Disconnect the cruise control command switch connector.
   3. Turn the ignition switch to ON.
   4. Measure the voltage between connector terminal and chassis ground.

      Connector and terminal 

      (ST3) No. 3 (+) - Chassis ground (-):

      (ST3) No. 4 (+) - Chassis ground (-):

   Is the voltage 5 V or more?

   Yes:  Go to  2.

   No:  Check the harness between cruise control command switch and ECM, and the steering roll connector for open or short circuit, or for poor contact.

2. CHECK CRUISE CONTROL COMMAND SWITCH CIRCUIT  .
   1. Turn the ignition switch to OFF.
   2. Using the tester, measure the resistance between cruise control command switch connector and chassis ground.

      Connector terminal 

      (ST3) No. 9 - Chassis ground:

   Is the resistance less than 10 Ω?

   Yes:  Go to  3.

   No:  Check for open circuit between cruise control command switch, ECM, and chassis ground and check the ECM.

3. PERFORM UNIT INSPECTION OF CRUISE CONTROL COMMAND SWITCH  .

   Measure the resistance between switch terminals when the cruise control command switch is not depressed.

   Terminals 

   No. 3 - No. 9:

   Is the resistance approx. 4 kΩ?

   Yes:  Go to  4.

   No:  Replace the cruise control command switch.

   Ref. to CRUISE CONTROL SYSTEM>CRUISE CONTROL COMMAND SWITCH .

4. PERFORM UNIT INSPECTION OF CANCEL SWITCH  .
   1. Remove the cruise control command switch. Ref. to CRUISE CONTROL SYSTEM>CRUISE CONTROL COMMAND SWITCH .
   2. Measure the resistance between switch terminals with the CANCEL switch pressed.

      Terminals 

      No. 3 - No. 9:

   Is the resistance approx. less than 1 Ω when the CANCEL switch is pressed?

   Yes:  Go to  5.

   No:  Replace the cruise control command switch. Ref. to CRUISE CONTROL SYSTEM>CRUISE CONTROL COMMAND SWITCH .

5. PERFORM UNIT INSPECTION OF SET/- SWITCH  .

   Measure the resistance between the switch terminals with the SET/- switch pressed.

   Terminals 

   No. 3 - No. 9:

   Is the resistance approx. 250 Ω when the SET/- switch is pressed?

   Yes:  Go to  6.

   No:  Replace the cruise control command switch. Ref. to CRUISE CONTROL SYSTEM>CRUISE CONTROL COMMAND SWITCH .

6. CHECK RES/+ SWITCH CIRCUIT  .

   Measure the resistance between the switch terminals with the RES/+ switch pressed.

   Terminals 

   No. 3 - No. 9:

   Is the resistance approx. 1, 500 Ω when the RES/+ switch is pressed?

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

   No:  Replace the cruise control command switch. Ref. to CRUISE CONTROL SYSTEM>CRUISE CONTROL COMMAND SWITCH .
