Possible Causes

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

1. Check for hard or intermittent DTC
   
   Turn ignition switch to OFF position. Connect scan tool to Data Link Connector (DLC). See USING SCAN TOOL  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 .
2. Check vehicle identification pins No. 1 & 2
   
   Turn ignition switch to OFF position. Access and disconnect RCM harness connector C2041A. Measure resistance between harness side of RCM connector C2041A, terminals No. 10 and 21 (Black wire, circuit No. 57). Measure resistance between harness side of RCM connector C2041A, terminals No. 13 and 21 (Black wire). See Figure . If resistance is less than 5 ohms in both circuits, go to next step. If resistance is more than 5 ohms in either circuit, repair appropriate black wire. See WIRING DIAGRAMS  . Go to step  5 .
3. Check vehicle identification pin No. 3
   
   Measure voltage between ground and harness side of RCM connector C2041A, terminal No. 14 (Light Blue/Pink wire, circuit No. 601). If voltage is more that 10 volts, replace RCM. Go to step  5 . If voltage is less than 10 volts, repair Light Blue/Pink wire. Go to step  5 .
4. 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 fault. 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.
5. 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. DO NOT clear any DTCs until all DTCs have been resolved. 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.
