- 1) VERIFY OPERATION OF THE ELECTRONIC OVERHEAD MODULE Turn the ignition on. With the scan tool, erase Electronic Overhead Module DTCs. With the scan tool, activate the Electronic Overhead Module self test. With the scan tool, read Electronic Overhead Module DTCs. Does the scan tool display DTC B2217-EVIC/EOM/CMTC INTERNAL? YES Replace the Electronic Overhead Module. See «OVERHEAD CONSOLE - SERVICE INFORMATION»(ref-247649-S17525378962007020100000) . Perform «BODY VERIFICATION TEST - VER 1»(ref-247618-S35373433422007020100000) . NO Test complete.
- 1) TEST FOR AN INTERMITTENT CONDITION Turn the ignition on. With the scan tool, record and erase any Electronic Overhead Module DTCs.

Yes Go To step 2) . No The condition that caused this code to set is not present at this time. Using the wiring diagram as a guide, inspect the wiring and connectors for an intermittent condition. Operate the system several times and recheck for active DTCs. Perform «BODY VERIFICATION TEST - VER 1»(ref-247618-S35373433422007020100000) .
- 2) VERIFY COMMUNICATION WITH FRONT CONTROL MODULE With the scan tool in ECU VIEW, read active modules on the bus. Does the scan tool show the Front Control Module active on the bus? Yes Go To step 3) . No Refer to the Communication category for the related symptoms. Perform «BODY VERIFICATION TEST - VER 1»(ref-247618-S35373433422007020100000) .
- 3) CHECK FRONT CONTROL MODULE FOR ACTIVE DTCs With the scan tool, erase FCM DTCs. Turn the ignition off. Wait approximately 10 seconds. Turn the ignition on. With the scan tool, read FCM DTCs.
