DIAGNOSTIC CODE INDEX
Scheme 43
Diagnostic Test
- 1) REPLACE THE COMPASS TEMPERATURE MODULE (EOM) When this code is set, the Compass Temperature Module (EOM) must be replaced. Repair Replace the Compass Temperature Module (EOM) in accordance with the Service Information. Perform «BODY VERIFICATION TEST - VER 1»(ref-285334-S04155882182008052100000) .
Refer to B1A32-UNIVERSAL GARAGE DOOR / HOMELINK SWITCH 1 STUCK for the diagnostic test procedure.
Refer to B1A32-UNIVERSAL GARAGE DOOR / HOMELINK SWITCH 1 STUCK for the diagnostic test procedure.
- 1) VERIFY OPERATION OF THE COMPASS TEMPERATURE MODULE Turn the ignition on. With the scan tool, erase Compass Temperature Module (EOM) DTCs. With the scan tool, activate the Compass Temperature Module (EOM) self test. With the scan tool, read Compass Temperature Module (EOM) DTCs. Does the scan tool display DTC: B2217-EVIC/EOM/CMTC INTERNAL? Yes Replace the Compass Temperature Module (EOM) in accordance with the service information. Perform «BODY VERIFICATION TEST - VER 1»(ref-285334-S04155882182008052100000) . No Test complete.
- 1) TEST FOR AN INTERMITTENT CONDITION Turn the ignition on. With the scan tool, record and erase any Compass Temperature Module (EOM) DTCs. Turn the ignition off, wait 10 seconds then turn the ignition on. With the scan tool, read DTCs. Does the scan tool display: B222D - ECU UNABLE TO CONFIGURE / CONFIGURATION NOT LEARNED? Yes Go to 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-285334-S04155882182008052100000) .
- 2) CHECK COMPASS TEMPERATURE MODULE (EOM) BUSSED INPUTS If equipped with Automatic Temperature Control, use the scan tool in Data Display and check the Automatic Temperature Control State in the Compass Temperature Module (EOM). Does the scan tool display: "Automatic Temperature Control-ON" in the Compass Temperature Module Data Display? Yes Replace the Compass Temperature Module (EOM) in accordance to the Service Information. Perform «BODY VERIFICATION TEST - VER 1»(ref-285334-S04155882182008052100000) . No Go to 3) .
- 3) 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 4) . No Refer to the Communication category for the related symptoms. Refer to «ELECTRONIC CONTROL MODULES - ELECTRICAL DIAGNOSTICS»(ref-285334) article. Perform «BODY VERIFICATION TEST - VER 1»(ref-285334-S04155882182008052100000) .
- 4) 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. Are any active DTCs present? Yes Refer to symptom list for problems related to the Front Control Module. Refer to «ELECTRONIC CONTROL MODULES - ELECTRICAL DIAGNOSTICS»(ref-285334) article. Perform «BODY VERIFICATION TEST - VER 1»(ref-285334-S04155882182008052100000) . No Replace the Front Control Module in accordance with the Service Information. Perform «BODY VERIFICATION TEST - VER 1»(ref-285334-S04155882182008052100000) .
- 1) PERFORM THE VEHICLE DEMAGNETIZING PROCEDURE NOTE: A blank compass display indicates that vehicle degaussing is required. NOTE: After demagnetizing, the vehicle will enter Auto Fast-Cal when the ignition is turned on. NOTE: Ensure that the correct compass variance is stored in the compass memory. See "Setting Compass Variance in the Service Information." Refer to the Service Information for the Compass Demagnetizing Standard Procedure. View repair. Repair When the Demagnetizing Procedure is complete, perform the Verification Test. Perform «BODY VERIFICATION TEST - VER 1»(ref-285334-S04155882182008052100000) .
