DTC 51-xx, 52-xx, 53-xx, 54-xx, 55-xx ("x" can be 0 thru 9 or A thru F): Internal Failure of the SRS Unit
NOTE:
- Before troubleshooting any of these DTCs, check the battery/system voltage and battery cable connections. If the voltage is low, repair the charging system or replace the battery before troubleshooting the SRS. If the battery/system voltage is now OK, ask the customer if the battery ever went dead or if the engine was started and run with the battery in a low state of charge. A dead battery may trigger one of these DTCs.
- Before doing this troubleshooting procedure, review SRS Precautions and Procedures (see PRECAUTIONS AND PROCEDURES ) and General Troubleshooting Information (see DTC (DIAGNOSTIC TROUBLE CODES) ).
- Clear the DTC memory (see CLEAR THE DTC MEMORY WITH THE HDS ).
- Turn the ignition switch ON (II), and check that the SRS indicator comes on for about 6 seconds and then goes off.
Does the SRS indicator stay on, and is DTC 51-xx, 52-xx, 53-xx, 54-xx, or 55-xx indicated?
YES -Replace the SRS unit (see SRS UNIT REPLACEMENT ).
NO -Intermittent failure, system is OK at this time. Go to TROUBLESHOOTING INTERMITTENT FAILURES . If another DTC is indicated, troubleshoot the DTC.
