All Models
- Ensure transmission is in Neutral or Park. Set parking brake. Inspect crankshaft pulley timing mark and timing mark indicator on timing belt or chain cover. Clean marks as required. Start engine and allow it to reach 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
table under IDLE SPEED & MIXTURE.
- Connect Suzuki scan tool (Tech1) to DLC located under driver's side dashboard. See Fig 1
. Set to FIXED SPARK MODE on scan tool. Aim timing light at timing cover timing marks. See Fig 3
. Ignition timing mark should be between 4-6 degrees BTDC. On Vitara 2.0L and Grand Vitara 2.5L V6 engine, if ignition timing is not within specification, loosen CMP sensor bolts and turn CMP sensor until timing marks line up.
- With engine idling, end FIXED SPARK MODE and check that timing is approximately 11-15 degrees BTDC. There should be a constant variation in timing within a few degrees of 11-15 degrees, indicating proper operation of electronic timing system. Also, check that timing advances when increasing engine speed. If results are not satisfactory, check the following for proper operation:
- Crankshaft Position Sensor
- Crankshaft Timing Belt Pulley
- Throttle Position Sensor
- Test Switch Signal Circuit
- Vehicle Speed Sensor
- Timing Belt Cover Installation
