Swift DOHC
- Ensure transmission is in Neutral or Park position and parking brake is set. Inspect crankshaft pulley timing mark and timing mark indicator on timing belt cover. See Figure . Clean marks as required. Start engine and warm to normal operating temperature. Turn all accessories off. Attach timing light to No. 1 spark plug wire. Ensure idle speed is correct. See IDLE SPEED SPECIFICATIONS (PFI) table.
- Remove protective cap from test connector located near ignition coil. See Fig 1 . Connect jumper wire between terminals "C" and "D" (between Black and Violet/Green wires of test connector). Aim timing light at crankshaft pulley and timing cover timing marks. If ignition timing is not within specification, loosen distributor hold-down bolt and rotate distributor to obtain correct ignition timing. Tighten distributor hold-down bolt and recheck ignition timing. See IGNITION TIMING table.
- Remove jumper wire from test connector. Ensure ignition timing advances with engine speed (RPM). If ignition timing does not increase, check TPS, test connector wiring circuit, engine start signal circuit and ECM.
CAUTION:
Driving with jumper wire installed in test connector will damage catalytic converter.
