CRUISE CONTROL: DYNAMIC RADAR CRUISE CONTROL SYSTEM: P0500: Vehicle Speed Sensor Malfunction
P0500 - Vehicle Speed Sensor Malfunction

DESCRIPTION

The dynamic radar cruise control system uses the same vehicle speed signal that is sent to the ECM for the SFI system. If DTC P0500 is detected, perform the diagnosis using the inspection procedure for DTC P0500 in the SFI system (for 2GR-FE) P0500. The speed signal is converted for use by the cruise control inside the ECM. Both the SFI system and the dynamic radar cruise control system can set DTC P0500, however, the detection conditions of the two systems are different.

INSPECTION PROCEDURE

This DTC may be output by the SFI system at the same time. In that case, perform troubleshooting for the SFI system first.

PROCEDURE

1. READ OUTPUT DTC (DTC P0500)

(a) Clear the DTCs Dynamic Radar Cruise Control System.

(b) Perform the following to make sure that the DTC detection conditions are met.

HINT
If the detection conditions are not met, the malfunction cannot be detected.

(1) With the shift lever in D, drive the vehicle for more than 10 seconds when the engine coolant temperature is more than 20°C (68°F).

(c) Check for DTCs Dynamic Radar Cruise Control System.

Result:





B -- GO TO SFI SYSTEM

A -- USE SIMULATION METHOD TO CHECK How To Proceed With Troubleshooting
