Dynamic Radar Cruise Control System

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

DESCRIPTION

The vehicle speed sensors detect the wheel speed and send the appropriate signals to the skid control ECU. The skid control ECU converts these wheel speed signals into a 4-pulse signal and outputs it to the ECM via the combination meter assembly. The ECM determines the vehicle speed based on the frequency of these pulse signals.





WIRING DIAGRAM

- Refer to SFI System (for 2GR-FSE) SFI System.

- Refer to SFI System (for 4GR-FSE) SFI System.

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) Connect the Techstream to the DLC3.

(b) Turn the engine switch on (IG).

(c) Turn the Techstream on.

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

(e) 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).

(f) Enter the following menus: Powertrain / Radar Cruise / Trouble Codes.

(g) Read the DTCs Dynamic Radar Cruise Control System.

Result:





B -- GO TO SFI SYSTEM (for 2GR-FSE) SFI System

C -- GO TO SFI SYSTEM (for 4GR-FSE) SFI System

A -- USE SIMULATION METHOD TO CHECK Electronic Circuit Inspection Procedure
