While performing electrical diagnosis & testing, always refer to the electrical schematics for specific circuit
and component information.
Diagnostic Procedure
1.CHECK RCM DTC
• Connect the X-431 scan tool to the Data Link Connector (DLC) - use the most current software available.
• Turn the ignition switch on, with the scan tool, view and erase stored DTCs in the RCM.
• Turn the ignition switch off, and wait a few seconds, then turn the ignition switch on.
• Wait one minute, and with the scan tool, view active DTCs in the RCM.
Is DTC B2501 present?
Ye s>>Go to the next step.
No
>>Go to step 5.
2.CHECK WARNING LAMP
• Turn ignition switch off, and wait a few seconds, then turn ignition switch on.
• Observe the airbag warning lamp.
Is the airbag warning lamp not illuminated with the ignition switch ON?
Ye s>>Go to the next step.
No
>>Go to step 4.
3.CHECK WARNING LAMP CIRCUITS
WARNING!
To avoid serious or fatal injury, turn ignition switch off, disconnect the negative battery cable and wait two min-
utes before proceeding.
• Disconnect the RCM electrical connector (1) (See
Restraints Control Module (RCM) Removal & Instal-
lation in Section 14 Restraints).
• Disconnect the instrument cluster electrical connec-
tor.
• Disconnect the front fuse and relay box electrical
connector B14.
NOTE :
Check connectors - Clean and repair as necessary.
• Check fuse F6.
• Measure the following circuits with a digital multim-
eter:
Harness connector C-106, J-100.
Harness for an open between the front fuse
and relay box electrical connector (terminal B4, B14 ) and instrument cluster C-001 (terminal 11 and 13).
Harness for open between the instrument cluster C-001 (terminal 17) and RCM electrical connector J-001 (terminal 7).

4.CHECK CONNECTORS
NOTE :
Diagnose and repair all active codes before diagnosing stored codes (See Restraints Control Module DTC List in
Section 14 Restraints).
• With the scan tool, record and erase all RCM DTCs.
• Using the electrical schematic as a guide, inspect the following:
Inspect the wiring and connectors of the related airbag system.
Look for any chafed, pierced, pinched, or partially broken wires.
Look for broken, bent, pushed out or corroded terminals.
Verify that there is good pin to terminal contact in the related connectors.
Were any problems found?
Ye s>>Repair as necessary.
No
>>Go to the next step.
5.CHECK DTC
• Reconnect all disconnected components and harness connectors.
• With the X-431 scan tool, read RCM DTCs.
• Refer to DTC Confirmation Procedure.
Is DTC B2501 still present?
Ye s>>Replace the RCM.
No
>>The system is now operating properly.
Reassemble the vehicle and road test to verify the customers complaint is repaired.
