Ignition Timing: 3.5RL

Start engine and run at 3000 RPM, with no loads and transmission in Park or Neutral, until radiator fan comes on. Allow engine to idle. Locate 2-pin service check connector (under glove box). Install Service Check Connector Tool (07PAZ-0010100) into service check connector. See Fig 1 .
Ensure idle speed is within specification. See IDLE SPEED under IDLE SPEED & MIXTURE. Remove engine cover and connect inductive timing light to test loop, located at No. 1 ignition coil (may be identified with White tape). Aim timing light toward pointer on timing belt cover. Red mark on crankshaft pulley should align with pointer on front of engine. See Fig 4 . If timing is not as specified (Red mark and pointer are not aligned), replace ECM/PCM. Timing is not adjustable. Remove service check connector tool from service check connector.
