Possible Causes

An incorrect module design level code could be caused by an RCM installed on wrong vehicle, an incorrectly programmed RCM or vehicle ID terminals not connected as expected.

  1. Check for hard or intermittent DTC

    Ensure ignition is off. Connect NGS tester to DLC. See USING NGS TESTER  under DIAGNOSTICS. Turn ignition switch to RUN position. Retrieve and record any continuous DTCs. See RETRIEVING FAULT CODES  under DIAGNOSTICS. Perform on-demand self-test. See ON-DEMAND SELF-TEST  under DIAGNOSTICS. If DTC C1414 was retrieved during on-demand self-test, fault is hard. Go to next step. If DTC C1414 was not retrieved, fault is intermittent. Go to step  4 .
    NOTE: For the following test, RCM connector terminal No. 14 should be open circuited.
  2. Check vehicle identification No. 3

    Turn ignition off. Disable air bag system. See DISABLING SYSTEM  under DISABLING & ACTIVATING AIR BAG SYSTEM. Access RCM. See RESTRAINTS CONTROL MODULE  under REMOVAL & INSTALLATION. Inspect RCM harness connector terminal No. 14 to ensure it is empty (contains no wire) and that no connection would be made when mated to RCM. See Figure . If terminal is empty (contains no wire), go to next step. If terminal is not empty (has wire attached), repair as necessary. See WIRING DIAGRAMS  .Go to next step.
    NOTE: For the following test, RCM connector terminals No 10 and No. 13 should be connected to ignition voltage.
  3. Check vehicle identification No. 1 & No. 2

    Measure voltage between ground and RCM harness connector terminal No. 10 (Green/Orange wire). See Figure . Measure voltage between ground and RCM harness connector terminal No. 13 (Green/Orange wire). If voltage is more than 9 volts, go to next step If voltage is less than 9 volts, repair open in appropriate Green/Orange wire. Go to next step.
  4. Check RCM programmed vehicle identification

    USING NGS TESTER, select PID/DATA MONITOR AND RECORD. Select PID VID #1, VID #2, VID #3. If VID #1 and VID #2 is IGNITION and VID #3 is NO CONNECT, go to next step. If VID #1, VID #2 and VID #3 is not as specified, replace RCM and go to step  6 .
  5. Check for intermittent fault

    Refer to continuous DTCs recorded in step  1 . If DTC retrieved in step 1 was an intermittent fault, check for cause of intermittent open on RCM harness connector terminal No. 10 (Green/Orange wire). Attempt to recreate fault by flexing wire harness and cycling ignition switch frequently. Repair any intermittent problems found. Go to next step. If DTC retrieved in step  1 was not an intermittent fault, go to next step.
  6. Check for additional DTCs

    Refer to continuous DTCs recorded in step  1 . If any continuous DTCs were retrieved, go to diagnostic trouble code identification table for direction to appropriate test. See DIAGNOSTIC TROUBLE CODE (DTC) IDENTIFICATION  table. If no continuous DTCs were retrieved, reactivate air bag system. See ACTIVATING SYSTEM  under DISABLING & ACTIVATING AIR BAG SYSTEM. Clear all DTCs. See CLEARING FAULT CODES  under DIAGNOSTICS.
