Step	Check	Yes	No
1 CHECK CRUISE CONTROL COMMAND SWITCH CIRCUIT. Remove the driver's airbag module. Refer to DRIVER'S AIRBAG MODULE . Disconnect the harness connector of cruise control command switch. Turn the ignition switch to ON. Measure the voltage between harness connector terminal and chassis ground. Connector & terminal (ST3) No. 4 (+) - Chassis ground (-): (ST3) No. 3 (+) - Chassis ground (-):	Is the voltage 5 V or more?	Go to step 2.	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. Turn the ignition switch to OFF. Remove the cruise control command switch. Refer to CRUISE CONTROL COMMAND SWITCH . Measure the resistance between harness connector terminal and chassis ground. Connector & terminal (ST3) No. 2 - Chassis ground:	Is the resistance less than 10 Ω?	Go to step 3.	Check for open circuit between cruise control command switch, ECM, and chassis ground and check the ECM.
3 CHECK CRUISE CONTROL COMMAND SWITCH. Measure the resistance between switch terminals when the cruise control command switch is not depressed. Terminals No. 2 - No. 3:	Is the resistance approx. 4 kΩ?	Go to step 4.	Replace the cruise control command switch. Refer to CRUISE CONTROL COMMAND SWITCH .
4 CHECK CANCEL SWITCH. Turn the ignition switch to OFF. Remove the cruise control command switch. Refer to CRUISE CONTROL COMMAND SWITCH . Measure the resistance between switch terminals with the CANCEL switch pressed. Terminals No. 2 - No. 3:	Is the resistance approx. less than 1 Ω when the CANCEL switch is pressed?	Go to step 5.	Replace the cruise control command switch. Refer to CRUISE CONTROL COMMAND SWITCH .
5 CHECK SET/- SWITCH. Measure the resistance between the switch terminals with the SET/- switch pressed. Terminals No. 2 - No. 3:	Is the resistance approx. 250 Ω when the SET/- switch is pressed?	Go to step 6.	Replace the cruise control command switch. Refer to CRUISE CONTROL COMMAND SWITCH .
6 CHECK RES/+ SWITCH. Measure the resistance between the switch terminals with the RES/+ switch pressed. Terminals No. 2 - No. 3:	Is the resistance approx. 1, 500 Ω when the RES/+ switch is pressed?	Replace the ECM. Refer to ENGINE CONTROL MODULE (ECM) . Refer to ENGINE CONTROL MODULE (ECM) . Refer to ENGINE CONTROL MODULE (ECM) .	Replace the cruise control command switch. Refer to CRUISE CONTROL COMMAND SWITCH .
