Dtc P0500: Vehicle Speed Sensor (Vss) Malfunction - Suzuki GRAND VITARA Owner's Manual

Step
18 Wire circuit check
1) Measure voltage between "RED/YEL" wire terminal of
radiator cooling fan relay No.3 connector and vehicle
body ground with ignition switch turned ON.
Is voltage 0 V?
19 Wire circuit check
1) Measure resistance between "RED/YEL" wire terminal of
radiator cooling fan relay No.3 connector and "E23-48"
terminal of ECM connector with ignition switch turned
OFF.
Is resistance below 5
20 Radiator cooling fan relay check
1) Check radiator cooling fan relay referring to "Radiator
Cooling Fan Relay Inspection: in Section 1F".
Is it in good condition?
