Body No. 2 Ecu Power Source Circuit
- Check MPX-B3, MPX-IG, D B/ANC, HAZ and PANEL fuses. See FUSE LOCATIONS (BODY NO. 2 ECU) table. If fuses are okay, go to next step. If fuse(s) are faulty, replace appropriate fuse and retest system operation.
- Turn ignition on. Measure voltage between driver-side junction block terminals MPX-IG and GND. See PIN VOLTAGE TESTS . Voltage should be 10-14 volts. Turn ignition off. Disconnect driver-side junction block connector. Measure voltage between driver-side junction block connector terminal GND2 and terminals MPXB, A/ANC, HAZ and PANEL1. If 10-14 volts are present, go to next test listed in appropriate SYMPTOM DIAGNOSIS table under TROUBLE SHOOTING . If 10-14 volts are not present, check wiring between body No. 2 ECU and ground. Repair wiring as necessary. See WIRING DIAGRAMS . If wiring is okay, go to next test listed in BODY NO. 2 CONTROL SYSTEM table under TROUBLE SHOOTING .
