Testing & Diagnostics ~244 words
  1. Perform PCM reset procedure. See «TESTS W/CODES - INTRODUCTION»(ref-16345) article. Start engine and turn headlights on. If DTC P1298 is indicated, go to next step. If DTC P1298 is not indicated, problem is intermittent. System is okay at this time. Check for poor connections or loose wires between ELD and PCM connectors. ELD is located in underhood fuse/relay box. See «WIRING DIAGRAMS»(ref-16355) article.
  2. Turn ignition and headlights off. Disconnect ELD 3-pin connector. Check for continuity between ground and ELD connector terminal No. 1 (Black wire). (Схема №9) If continuity exists, go to next step. If continuity does not exist, repair open in Black wire between ELD and ground connection G401 (located above hood release).
  3. Using backprobe set, check for continuity in Green/Red wire between PCM 16-pin connector "D" terminal D16 and ELD connector terminal No. 2. (Схема №4)and (Схема №9). If continuity exists, go to next step. If continuity does not exist, repair open in Green/Red wire between PCM and ELD. See «WIRING DIAGRAMS»(ref-16355) article.
  4. Reconnect ELD 3-pin connector. Start engine and allow it to idle. Using backprobe set, measure voltage between PCM 32-pin connector "A" terminal A9 (Brown/Black wire) and PCM 16-pin connector "D" terminal D16 (Green/Red wire). (Схема №1)and (Схема №4). While measuring voltage, turn headlights on. If voltage does not decrease, replace ELD. If voltage decreases, substitute a known-good PCM and recheck. If symptom or problem goes away, replace original PCM.
