(1) Disconnect the connector of the camshaft position sensor, and connect the special tool (test harness: MB991348) across the disconnected
connector parts. (Connect the tool to all terminals.)
(2) Connect the special patterns pickup of the analyzer to the terminal (2) of the camshaft position sensor connector.
(3) Disconnect the connector of the crankshaft position sensor, and connect the special tool (test harness: MD998478) across the disconnected
