(1) Complete drive cycles in following order: Mode 1, Mode 3. See OBD II-B DRIVE CYCLE MODES . If Mode 3 monitors are not complete, perform Mode 2, and perform Mode 3 again. Repeat QUICK TEST  to verify no codes exist.
(2) Complete drive cycles in following order: Mode 1, Mode 2, Mode 3, Mode 2, Mode 3. See OBD II-B DRIVE CYCLE MODES . 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 flowing order: Mode 1, Mode 2, Mode 3, Mode 2. See OBD II-B DRIVE CYCLE MODES . Check to ensure monitors have completed. If monitors do not complete, Repeat entire drive cycle. Repeat QUICK TEST  to verify no codes exist.
(4) Transmission/transaxle fault is indicated. See appropriate AUTOMATIC TRANSMISSION article.
(5) Perform complete drive cycle (Mode 1,2, and 3). See OBD II-B DRIVE CYCLE MODES . If DTC P1000 remains, go to CIRCUIT TEST QC .
(6) PCM internal circuit fault is indicated. Replace PCM.
