4-Cylinder Ignition Timing: Loyale

Ensure engine is at normal operating temperature and idle speed is correct. Set transaxle in Park (A/T) or Neutral (M/T) position.
Ensure throttle valve is closed and throttle position sensor is correctly adjusted. Connect 2 test mode connectors. See Fig 1 .
NOTE: When checking timing, CHECK ENGINE warning light will come on. This is not an indication of a problem. Ignition timing cannot be set if idle contacts in TPS are open and test mode connectors are not connected.
Observe timing marks, located on crankshaft pulley. See the 4-CYLINDER IGNITION TIMING SPECIFICATIONS table. If necessary, adjust ignition timing by loosening distributor hold-down bolt and rotating distributor. After adjusting ignition timing, unplug test mode connectors.
