B222A-VEHICLE LINE MISMATCH

For a complete wiring diagram, refer to appropriate SYSTEM WIRING DIAGRAMS article .

When powered, the Electronic Pedestrian Protection Module (EPPM) performs an internal self test. The repair of this fault centers on verifying the EPPM and Totally Integrated Power Module (TIPM) configuration. Configuration covering the model year, vehicle line, country code, body style, and LHD/RHD, and checking for differences between what is programmed in the EPPM and what is actually on the vehicle.

The EPPM checks its feature configuration for a stored Vehicle Line and Country Code continuously 12 seconds after initialization. The monitoring rate is done at startup during the first 16 seconds of the key cycle.

This DTC sets when the ORC detects a mismatch between the Vehicle Configuration and the EPPM configuration with in the early initialization. Once the code sets in this ignition cycle it stays active for this ignition cycle.

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Refer to STANDARD PROCEDURE .

1. DETERMINE ACTIVE OR STORED DTC NOTE: Make sure the battery is fully charged. Turn the ignition on. Wait 12 seconds, then with the scan tool, read all active EPPM DTCs. Is the DTC active or stored?

B276C-2B-RIGHT HOOD HINGE PEDESTRIAN PROTECTION SQUIB - WIRES SHORTED TOGETHER

For a complete wiring diagram, refer to appropriate SYSTEM WIRING DIAGRAMS article .

For description of the Electronic Pedestrian Protection Module (EPPM), refer to ACTUATOR, ELECTRONIC PEDESTRIAN PROTECTION HOOD HINGE, DESCRIPTION . For operation of the EPPM, refer to MODULE, ELECTRONIC PEDESTRIAN PROTECTION, OPERATION . When powered, the EPPM sends a test current to the Electronic Pedestrian Protection actuator squibs to verify the integrity of the squib and the wiring. Use of the Supplemental Restraints System (special tool #8443A, SRS Load Tool) in the tests below substitutes a suspect EPPM actuator squib with a known good component. The use of the (special tool #8443-25, 56 Way ACM Adapter) provides a test point, as well as a method for opening the shorting bar connections within the harness connector. The EPPM is powered by a Ignition Run/Start (F943) control output circuit through the 32 pin connector side of the 56 way EPPM module connector. The 32 pin connector side of the 56 way EPPM module connector provides ground.

The EPPM sends out a 40mA diagnostic current on each squib voltage supply circuit at power up and every 200ms thereafter while the ignition is in on.

The EPPM will set this DTC if it detects low resistance between the EPPM Squib 2 circuits. The DTC will set when the EPPM squib 2 circuits become shorted together for more than 2.6 seconds. The DTC will go from active to stored when the module sees a recovery from the shorted together for more than 2.6 seconds.

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Refer to STANDARD PROCEDURE .

1. Before attempting to repair any electronic pedestrian protection (EPPM) system, technicians should be familiar with and fully understand the system operation. Refer to EPPM System Description and Operation for complete details. Refer to «MODULE, ELECTRONIC PEDESTRIAN PROTECTION, DESCRIPTION»(/chrysler/town-country/v-2010-2016/remont/airbag/#restraints-service-information) . Refer to «MODULE, ELECTRONIC PEDESTRIAN PROTECTION, OPERATION»(/chrysler/town-country/v-2010-2016/remont/airbag/#restraints-service-information) . The following should be used as a checklist to be completed in its entirety prior to referencing specific EPPM Diagnostic Procedures. FOLLOW THE BASIC OUTLINE SET FORTH IN THE SIX-STEP TROUBLESHOOTING PROCEDURE Verification of complaint. Verification of any related symptoms. Symptom analysis. Problem isolation. Repair of isolated problem. Verification of proper operation. TAKE INTO ACCOUNT CURRENT VEHICLE CONDITION, REPAIR HISTORY, AND TECHNICAL SERVICE BULLETINS (TSBs) Verify that there are no outward signs of vehicle damage or effects from a collision that could impact the proper operation of the EPPM system. Check for aftermarket vehicle accessories that may have been installed improperly or could interfere with the system. Check the vehicle repair history for repairs that may relate to the current condition. Check for current Technical Service Bulletins (TSBs) for the EPPM system related to the customer concern. If a TSB applies, follow the procedure outlined in the TSB. DIAGNOSE ONLY THOSE FAILURES THAT ARE ACTIVE AND CAN BE REPRODUCED Check the control module central to the subsystem that is exhibiting the condition for active DTCs. For an intermittent failure that is not active at the time of vehicle inspection, perform the EPPM SYSTEM INTERMITTENT TEST diagnostic procedure and document the event on the repair order. Refer to «EPPM SYSTEM INTERMITTENT TEST»(/chrysler/town-country/v-2010-2016/remont/collisionavoidance/#electronic-pedestrian-protection-epp-module-electrical-diagnostics__eppm-system-intermittent-test) . ADDRESS ACTIVE DIAGNOSTIC TROUBLE CODES (DTCs) IN THE CORRECT ORDER Low/High Voltage and Serial Data Loss of Communication Codes. Module Internal Failure and Configuration Mismatch Codes. Circuit specific DTC failures. Should the malfunction still be present after conducting this Pre-diagnostic Procedure, technicians should continue to the appropriate DTC procedure. Refer to the «DIAGNOSTIC CODE INDEX»(/chrysler/town-country/v-2010-2016/remont/collisionavoidance/#electronic-pedestrian-protection-epp-module-electrical-diagnostics__diagnostic-code-index) . Was the Pre-Test reviewed and is the DTC still present? Yes Perform the appropriate DTC procedure. Refer to the «DIAGNOSTIC CODE INDEX»(/chrysler/town-country/v-2010-2016/remont/collisionavoidance/#electronic-pedestrian-protection-epp-module-electrical-diagnostics__diagnostic-code-index) . No Test Complete.

1. Perform the EPPM System Verification Test NOTE: If the EPPM has been replaced, the EPPM Initialization Procedure must be performed to clear the EPPM Unlocked DTC and bring the module to a full state of readiness. Refer to the «DIAGNOSTIC CODE INDEX»(/chrysler/town-country/v-2010-2016/remont/collisionavoidance/#electronic-pedestrian-protection-epp-module-electrical-diagnostics__diagnostic-code-index) . Remove any special tools or jumper wires and reconnect all previously disconnected components - except the Battery. If equipped with the keyless ignition, use this ignition on warning for EPPM. WARNING: Disconnect the 12-volt battery wait two minutes before proceeding, remove the EPPM fuse, connect the 12-volt battery, wait two minutes before proceeding. Cycle the ignition to the On position, then reconnect the EPPM fuse. Wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury. If equipped with the standard key ignition, use this ignition on warning. WARNING: Turn the ignition on, then reconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury. Connect the scan tool to the Data Link Connector - use the most current software available. With the scan tool, erase stored DTCs in all airbag system modules. Perform module reset. NOTE: If equipped with an Airbag On - Off switch, read the DTCs in all switch positions. Exercise the EPPM System to duplicate the appropriate monitor conditions for any DTCs that were set. Wait one minute, and read active codes, if there are none present, read the stored codes. If the scan tool shows any active or stored codes, return to the «DIAGNOSTIC CODE INDEX»(/chrysler/town-country/v-2010-2016/remont/collisionavoidance/#electronic-pedestrian-protection-epp-module-electrical-diagnostics__diagnostic-code-index) and follow the path specified for that trouble code. If no active or stored codes are present, the repair is complete. Are any DTCs present or, is the original condition still present? Yes Refer to the «DIAGNOSTIC CODE INDEX»(/chrysler/town-country/v-2010-2016/remont/collisionavoidance/#electronic-pedestrian-protection-epp-module-electrical-diagnostics__diagnostic-code-index) and perform the appropriate diagnostic procedure. No If the battery was disconnected for any reason, you must perform the Battery Reconnection procedure. Refer to the appropriate Service Information. Repair is complete.
