T 2 CRUISE CONTROL SYSTEM PRESS 45UOTX-209 Inspection Procedure Quick inspection 1. Connect a 1.4W test light between terminals D and F, of the cruise control unit connector. u Note There is no wire in terminal D of the connector. Push the test light through the connector and touch the cor- responding pin on the control unit. 2. Turn the ignition switch to ON. 3. Shift the selector lever to D or R range. 4. Verify that the MAlN switch is off. (The MAlN indicator light will be off .) 5. Turn the RESUMEIACCEL switch and the MAlN switch simultaneously to activate the system inspection. The MAlN indicator light will come on. 6. Operate each switch as described below and obtain the problem code numbers. Note The cruise control system will not operate in self-diag- nosis mode. 7. After retrieving the code(s), press the MAlN switch to deactivate the system inspection. The MAlN indicator light will go off. 8. Follow the action corresponding to the problem code. --, Service Code Table Press SETICOAST switch Procedure Press RESUMEIACCEL switch Pattern of output signal (Test light) ON OFF nn M nn Depress brake pedal ON OFF ON Drive vehicle above 40 km/h (25 MPH) Turn ignition switch to ON and shift the selector lever to P or N range (For AT) Depress clutch pedal (For MT) Code No. oN OFF Action lnspect cruise control switch (Refer to page T-106) lnspect cruise control switch (Refer to page T-106) lnspect stoplight switches (Refer to pages T-105 and T-56) lnspect parwneutral switch (Refer to section K) or clutch switch (Refer to page T-105) lnspect vehicle speed sensor or wire harness (Refer to page T-106) Gartner Banana
