Test 2C: No Response From Orc

WARNING: This page is about a different car, the 2001 Dodge Grand Caravan, 2001 Dodge Caravan, 2001 Chrysler Voyager, and 2001 Chrysler Town & Country. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Prior to performing any air bag system test, go to PRETEST INSPECTION & DIAGNOSTIC PROCEDURE  under DIAGNOSTICS. Perform air bag verification test after all repairs unless otherwise directed. See TEST VER-1: AIR BAG VERIFICATION TEST  under DIAGNOSTIC TESTS.
Check for FCM DTCs. If FCM DTCs are present, diagnose and resolve FCM malfunction(s) prior to performing this procedure.
  1. Disable air bag system. See DISABLING SYSTEM  under DISABLING & ACTIVATING AIR BAG SYSTEM. Access and disconnect ORC connector. See OCCUPANT RESTRAINT CONTROLLER (ORC)  under REMOVAL & INSTALLATION. Turn ignition switch to ON position. Connect negative battery cable. Using 12-volt test light connected to ground, probe ORC RUN and RUN-START circuits at ORC connector terminals No. 14. (Pink-Orange wire) and No. 15 (Pink-Violet). See Figure . If test light illuminates at both terminals, go to next step. If test light does not illuminate at both terminals, repair open circuit or blown fuse in fused ignition switch output circuits (Pink-Orange and Pink-Violet wires). See WIRING DIAGRAMS  .
  2. Turn ignition switch to OFF position. Disconnect negative battery cable and wait 2 minutes. Measure resistance between ground and ORC connector terminal No. 16 (Black wire). If resistance is less than 5 ohms, go to next step. If resistance is more than 5 ohms, repair open circuit in Black wire between ORC connector and ground.
    3. NOTE: Ensure there is PCI bus communications with other vehicle control modules. Diagnose and resolve any PCI bus malfunctions before proceeding to next step.
  3. Turn ignition switch to ON position. Connect negative battery cable. Using Scope Input Cable (CH7058), connect scope input cable to DRB channel one connector. Using Cable-to-Probe Adapter (CH7062) and Red and Black test probes, connect cable-to-probe adapter and Red and Black test probes to scope input cable. On DRB select DRB STANDALONE, LAB SCOPE, LIVE DATA and 12 VOLT SQUARE WAVE. Press F2 for scope and ENTER to select channel. Press F2 and use down arrow to set voltage range to 20 volts. Press F2 when voltage range is set. Connect Black test probe to body ground. Connect Red test probe to ORC connector terminal No. 21 (White-Violet wire). If voltage reading on DRB display pulses from 0-7.5 volts, replace ORC. If voltage reading on DRB display does not pulse from 0-7.5 volts, repair open circuit in White-Violet wire (PCI bus).
