APPLIES TO: Sorento
SERVICE TIP:
When diagnosing a compass that does not change direction, or when performing a position (bearing) correction on a Sorento compass (Sorento Technical Highlights, Body Electrical pg. 17), be aware that the compass requires a Vehicle Speed Sensor (VSS) input to initiate the correction. If the "DRT" indicator keeps flashing after two or more complete 360 degree turns at 12.5 MPH or less, check for VSS input at pin 2 of C-05 at the multi-meter. VSS input can be checked by backprobing between pin 2 of C-05 and ground with a volt meter and driving very slowly, or by jacking up a rear wheel and turning it by hand with the ignition key ON. Voltage should switch up and down from 0 to 7-8 volts.
