CHECK IPDM E/R INPUT VOLTAGE
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R and horn relay.
3. Check continuity between IPDM E/R connector E122 terminal 45 and horn relay connector H-1 terminal 1.
  45 - 1 : Continuity should exist.
4. Check continuity between IPDM E/R connector E122 terminal 45 and ground.
  45 - Ground : Continuity should not exist.
OK or NG

OK: Further inspection is necessary. Refer to "SYMPTOM CHART ".

NG: Repair or replace harness
