Install Service Check Connector Tool (07PAZ-0010100) to 2-pin service check connector before checking timing. Ensure idle speed and ignition timing are set to 13-17° BTDC (Red mark) at 730-830 RPM for automatic transmission or 750-850 for manual transmission. For timing mark identification, refer to illustration. See Fig 1.
