Pinpoint Test - DTC: I — 2016 workshop reference 1850

Using a diagnostic scan tool, perform RCM self-test. DIAGNOSTIC TIP: When viewing Diagnostic Trouble Codes (DTCs) with the passenger safety belt buckle switch disconnected, an open circuit fault is normally retrieved. A Belt Tension Sensor (BTS) circuit fault will also be present in the OCSM, since the passenger safety belt buckle switch shares a connector with the Belt Tension Sensor (BTS).
