DTC P1297: ELECTRICAL LOAD DETECTOR (ELD) LOW VOLTAGE INPUT Honda CR-V I рестайлинг

1. Perform PCM reset procedure. See SELF-DIAGNOSTICS - INTRODUCTION article. Start engine. Turn headlights on. If DTC P1297 is indicated, go to next step. If DTC P1297 is not indicated, problem is intermittent. System is okay at this time. Check for poor connections or loose wires at PCM and ELD connectors. ELD is located in underhood fuse/relay box. See appropriate wiring diagram in WIRING DIAGRAMS article.
2. Using backprobe set, measure voltage between ground and ELD connector terminal No. 3 (Green/Red wire). (Scheme 26) If about 4.5 volts does not exist, go to next step. If about 4.5 volts exists, replace ELD.
3. Turn ignition off. Disconnect PCM 32-pin connector "A". Check for continuity between ground and PCM 32-pin harness connector "A" terminal No. 30 (Green/Red wire). see scheme 1 If continuity exists, repair short in Green/Red wire between PCM 32-pin connector "A" and ELD. See appropriate wiring diagram in WIRING DIAGRAMS article. If continuity does not exist, substitute a known-good PCM and recheck. See SUBSTITUTING PCM in SELF-DIAGNOSTICS - INTRODUCTION article. If symptom or problem goes away, replace original PCM.
