DTC P0500 Vehicle Speed Sensor Malfunction
DTC P0503 Vehicle Speed Sensor Circuit Malfunction
DESCRIPTION
The 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. The speed signal is converted for use by the cruise control inside the ECM.
Both the SFI system and the cruise control system can set DTC P0500, however the detection conditions of the two systems are different.

Vehicle Speed Signal Circuit between Radio Receiver and Combination
Meter
DESCRIPTION
This circuit is necessary for the ASL (Auto Sound Leveliser) built into the
radio receiver.
Speed signals are received from the combination meter and used for the ASL.
The ASL function automatically adjusts the sound data in order to enable hearing
the clear audio sound

Check for short circuit
(a) If the wire harness is ground shorted (Fig. 5), locate the section by
conducting a resistance check with the body ground (below).
(b) Check the resistance with the body ground.
(1) Disconnect connectors A and C and measure
the resistance.
Standard resistance (Fig. 6)
