(4) If no voltage, refer to HORNS WILL NOT SOUND. If voltage is OK, go to step Step 5. (5) Using ohmmeter, test ground wire for continu- ity to ground. (6) If no ground repair as necessary. replace horn. HORNS SOUND CONTINUOUSLY CAUTION: Continuous sounding of horns may The horn switch (membrane) sometimes can be the cause without the switch being depressed. (1) Remove the horn relay from the intelligent power module. (2) Using a continuity tester, test continuity from the X3 cavity of the horn relay to ground. Refer to the (a) If continuity is detected, proceed to step Step 3. (3) Remove the airbag trim cover from the steering wheel and disengage horn connector. (4) Install horn relay into Integrated Power Mod- ule (IPM). (a) If horn does not sound, replace airbag trim cover. (b) If horn sounds, repair grounded X3 circuit from IPM to clockspring in the steering column. HORNS WILL NOT SOUND Check horn fuse # 8 in the IPM.
