DTC P1560: BACK-UP VOLTAGE CIRCUIT MALFUNCTION Subaru Forester SF рестайлинг

  1. Perform basic diagnostic procedure. See «BASIC DIAGNOSTIC PROCEDURE»(ref-11745-S33755862182000112700000). Turn ignition off. Using DVOM connected to ground, backprobe ECM connector B136 (30-pin connector) terminal No. 9. (Схема №7) If voltage is more than 10 volts, repair poor terminal contact in ECM connector. If voltage is not more than 10 volts, go to next step.
  2. Turn ignition off. Disconnect ECM connector B136 (30-pin connector). Using an ohmmeter connected to ground, measure resistance at ECM connector B136 (30-pin connector) terminal No. 9. If resistance is less than 10 ohms, locate and repair short to ground in wiring between ECM and battery. See WIRING DIAGRAMS article. If resistance is not less than 10 ohms, go to next step.
  3. Check condition of fuse SBF-5 (30-amp) in main fuse box, located in left side of engine compartment. Replace fuse if open. If fuse is okay, locate and repair open circuit in wiring and check for poor terminal contact in connectors between ECM and battery. Clear memory and perform verification procedure. See «CLEARING DIAGNOSTIC TROUBLE CODES»(ref-11745-S21987207372000112700000) and «VERIFICATION PROCEDURE»(ref-11745-S19795024722001010900000).
