  1. 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.
  2. On 2.5TL and 3.0CL, connect inductive timing light to No. 1 spark plug wire. On 3.2TL, connect timing light to service loop next to ignition coil No. 1 (White wire between ignition coil No. 1 and ignition control module). On 3.5RL, remove strut brace and engine cover. Connect inductive timing light to No. 1 spark plug wire.
  3. On all models, ensure idle speed is within specification. See IDLE SPEED  under IDLE SPEED & MIXTURE. Red mark on crankshaft pulley should align with pointer on front of engine. See Fig 2. If timing is not as specified (Red mark and pointer are not aligned), replace ECM/PCM. Timing is not adjustable.
