(1) See appropriate DIAGNOSTIC TEST. If fault code is engine related, see appropriate SELF-DIAGNOSTICS article in ENGINE PERFORMANCE section.
(2) Complete drive cycles in following order: Mode 1, Mode 2, Mode 3, Mode 2, Mode 3. See DRIVE CYCLES . Check to ensure monitors related to area of fault have completed (E.g. If EGR system fault is suspected, check EGR monitor for completion code). Repeat QUICK TEST to verify no codes exist.
(3) Complete drive cycles in following order: Mode 1, Mode 2, Mode 3, Mode 2. See DRIVE CYCLES . Check to ensure monitors have completed. If monitors do not complete, Repeat entire drive cycle. Repeat QUICK TEST to verify no codes exist.
(4) Complete drive cycles in following order: Mode 1, Mode 3. If mode 3 monitors are not complete, perform Mode 2, and perform Mode 3 again. Repeat QUICK TEST to verify no codes exist.
(5) During KOEO and KOER self-test disregard DTC P1000 and continue testing. For Continuous Memory DTC P1000, see READING CODES under SELF-DIAGNOSTICS.
(6) Replace PCM. Repeat QUICK TEST to verify no codes exist.
