(2) Using a continuity tester, test continuity from the X3 cavity of the horn relay to ground. Refer to (a) If continuity is detected, proceed to step Step 3. (b) If NO continuity, replace the horn relay. (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. If fuse is blown, check for a shorted switch in the airbag module. and FUSE BLOWN (1) Verify condition of battery terminals and volt- age, (Refer to 8 - ELECTRICAL/BATTERY SYSTEM (2) Using a voltmeter, test for battery voltage at both sides of horn fuse 7. If voltage is OK, on both (3) Using a suitable ammeter in place of the fuse, test amperage draw of the horn circuit. If amperage (4) Remove the horn relay from the IPM. If the amperage draw drops to 0 amps, the horn switch or (5) Disengage a wire connector from one of the horns. If amperage drops and the connected horn (6) Using a continuity tester, with the horns dis- connected test continuity of the X2 cavity of the horn relay to ground. If continuity is detected, the circuit FUSE OK (1) Remove the horn relay from the intelligent power module. (2) Using a continuity tester, Depress horn switch and test continuity from the X3 cavity of the horn (a) If continuity is detected, proceed to Step 3. (3) Using a suitable jumper wire, jump across the fuse F62 cavity and the X2 cavity of the horn relay in (a) If the horn sounds, replace the horn relay. (4) Remove airbag trim cover from steering wheel. Refer to ELECTRICAL, RESTRAINTS. (5) Test continuity across horn switch connectors with horn switch depressed. (a) If continuity is detected, repair open circuit between the relay and the horn switch. (b) If NO continuity, replace airbag trim cover. (6) Install horn relay into intelligent power mod- ule. (7) Disengage wire connectors from horns. a voltmeter, with the horn switch depressed test voltage across horn connector termi- (a) If voltage is detected, replace horns. (b) If NO voltage, proceed to step Step 9. (9) With the horn switch depressed, test for volt- age between the X2 circuit and ground. (a) If voltage OK, repair system ground at right cowl area. (b) If NO voltage, repair open X2 circuit between the relay and the horns. Fig. 1 Horn Connector 8H - 4 HORN RS HORN (Continued) |
