Land Cruiser URJ200 URJ202 GRJ200 VDJ200 CRUISE CONTROL

Keep in mind the following points when inspecting the dynamic radar cruise control system.

Connecting terminals TC and CG of the DLC3 causes the system to enter self-diagnostic mode. If a malfunction is present, DTCs will be output.

Select the item below in the Active Test, and then check that the cruise control SET indicator light illuminates ().

Using the intelligent tester, perform the Active Test ().

Using the intelligent tester, read the Data List ().

When the clutch pedal is released, the ECM receives positive (+) battery voltage through the LH-IG fuse. While depressing the clutch pedal, the clutch switch sends a signal to terminal D*1 or CLSW*2 of the ECM. The ECM cancels cruise control when terminal D*1 or CLSW*2 receives the signal.

Using the intelligent tester, read the Data List ().

If a malfunction (a rapid change in vehicle speed) in the vehicle speed signal being output from the master cylinder solenoid (skid control ECU) is detected while the cruise control is in operation, the ECM determines there to be a momentary interruption and noise, and outputs a DTC.

This DTC indicates the internal abnormalities of the ECM.
