CRUISE CONTROL SYSTEM(except 1ND-TV, 8NR-FTS), Diagnostic DTC:P0500

DTC Code DTC Name
P0500 Vehicle Speed Sensor 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 diagnosis using the inspection procedure for DTC P0500 in the SFI system*1 or ECD system*1. 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.
