DTC P1297 - Electrical Load Detector (Eld)
- Perform PCM reset procedure. See PCM RESET PROCEDURE/CLEARING CODES. Start engine. Turn headlights on. If DTC P1297 is not indicated, system is okay at this time. Failure is intermittent. Check for poor connections or loose wires at ELD and PCM connectors. See WIRING DIAGRAMS
section. If DTC P1297 is indicated, turn ignition and headlights off.
- Disconnect ELD connector. Turn ignition on. Measure voltage between ELD connector terminal No. 3 (IG1) and ground. See Fig 1
. If battery voltage exists, go to next step. If battery voltage does not exist, repair open in wire between underdash fuse/relay box and ELD. See WIRING DIAGRAMS
section.
- Measure voltage between ELD connector terminal No. 2 (EL) and ground. See Fig 1
. If approximately 5 volts exists, replace ELD. If approximately 5 volts does not exist, turn ignition off.
- Disconnect PCM connector "D". See Figure
. Check for continuity between PCM connector terminal D16 and ground. If continuity exists, repair short in wire between PCM connector terminal D16 and ELD. See WIRING DIAGRAMS
section. If continuity does not exist, substitute a known-good PCM and recheck. If symptom or problem goes away, replace original PCM.
