The Restraints Control Module (RCM) ground pin must be connected to the vehicle chassis in the immediate location
of the RCM mounting area.
WARNING!
After installing the Restraints Control Module (RCM), make sure all of the connectors are firmly connected, and
the harness is routed properly. The resistance between the RCM housing and the vehicle body should be less
than 100 m.

DTC Confirmation Procedure:
Before performing the following procedure, confirm that battery voltage is more than 12 V.
• Turn ignition switch off.
• Connect the X-431 scan tool to the Data Link Connector (DLC) - use the latest software available.
• Turn ignition switch on.
• With the scan tool, record and erase stored DTCs in the RCM.
• Turn ignition switch off and wait for a few seconds.
• Turn ignition switch on then select view DTC.
• If the DTC is detected, the DTC condition is current. Go to Diagnostic Procedure - Step 1.
• If the DTC is not detected, the DTC condition is intermittent (See Diagnostic Help and Intermittent DTC Trou-
bleshooting in Section 14 Restraints for more information).
Diagnostic Guide Lines
Observe the following guide lines while diagnosing this DTC:
•Troubleshoot any Engine Control Module (ECM) charging/cranking DTCs before proceeding.
• If the warning lamp goes out immediately after the warning lamp flashed for6-7seconds, this indicates that
the system is OK.
• If the warning lamp is on for6-7seconds continuously, then goes out, or the warning lamp is on continuously,
this indicates that there are history DTCs in the system. Use the Scan Tool to erase the DTCs.
• If any other condition occurs, use the Scan Tool to erase the history DTCs first, then check the warning lamp.
If the warning lamp does not go out immediately after the warning lamp flashes for6-7seconds when using
the Scan Tool, erase the history DTCs first.
• In the course of troubleshooting the airbag system, make sure the system power supply is shut off, and wait
two minutes for the system capacitor to discharge.
• The squib circuit connectors integrate a shortingspring (which prevents the airbag from deploying unintention-
ally due to static electricity by shorting the positive wire to the negative wire in the squib circuit when the con-
nectors are disconnected). Therefore, if the airbag electrical connector or spiral cable electrical connector is
damaged or improperly connected, the shorting spring may not be released when the electrical connector is
connected.
• The following tools are required to perform the DTC diagnostic procedure:
X-431 Scan Tool
Airbag Special Load Tool
Digital Multimeter

Clearing Service Monitor Lamp
Perform the following to clear the service monitor lamp:1. Turn the ignition switch off.
2. Press down and hold the Mode switch.
3. Turn the ignition switch on.
4. Release the Mode switch.
5. Press the Mode switch and the Clock switch simultaneously within 30 seconds and hold less than 2 seconds to clear the mileage maintenance identification.
Diagnostic Help
1. The X-431 scan tool connects to the Data Link Connector (DLC) and communicates with the vehicle electronicmodules through the class two serial data circuit.
2. Confirm that the malfunction is current and carry-out the diagnostic tests and repair procedures.
3. If the DTC cannot be deleted, it is a current fault.
4. Use a digital multimeter to perform voltage readings on electronic systems.
5. Refer to any Technical Bulletins that issued.
6. Visually inspect the related electrical wiring harness.
7. Inspect and clean all Instrument Cluster (IC) grounds that are related to the DTC.
8. If numerous trouble codes were set, use the electrical schematic and look for any common ground circuits or voltage supply circuits that may apply to the DTC.
Intermittent DTC Troubleshooting
If the failure is intermittent, perform the following:
•Check for loose connectors.
• Look for any chafed, pierced, pinched, or partially broken wires.
• Monitor the scan tool data relative to this circuit.
• Wiggle the related electrical wiring harness and connectors while looking for an interrupted signal on the
affected circuit.
• If possible, try to duplicate the conditions under which the DTC set.
• Look for the data to change or for the DTC to reset during the wiggle test.
• Look for broken, bent, pushed out or corroded terminals.
• Inspect the sensor and mounting area for any condition that would result in an incorrect signal, such as dam-
age or foreign material.
• A data recorder, and/or oscilloscope should be used to help diagnose intermittent conditions.
Ground Inspection
Ground connections are very important to the proper operation of electrical and electronic circuits. Ground connec-
tions are often exposed to moisture, dirt and other corrosive elements. The corrosion (rust) can become an unwanted
resistance. This added resistance can alter the way a circuit works.
Electronically controlled circuits are very sensitive to proper grounding. A loose or corroded ground can drastically
affect an electronically controlled circuit. A poor or corroded ground can effect the circuit. Perform the following when
inspecting a ground connection:
1. Remove the ground bolt or screw.
2. Inspect all mating surface for tarnish, dirt, rust, etc.
3. Clean as required to assure good contact.
4. Reinstall bolt or screw securely.
5. Inspect for add-onaccessories which may be interfering with the ground circuit.
6. If several wires are crimped into one ground eyelet terminal, check for proper crimps. Make sure all of the wires are clean, securely fastened and providing a good ground path. If multiple wires are crimped to one eyelet, make
sure no excess wire insulation has been crimped creating a bad ground.
