To avoid damage to control unit, only connect and disconnect the two connectors on control unit when ignition is switched off.
Terminal 1 of ignition coils must not be short-circuited to GND, e.g. as antitheft protection.
Only install original ignition system components.
Do not operate ignition system at starting speed unless all of the ignition cables are connected.
No tests such as holding ignition cable 4 at a distance to GND, unplugging a spark plug connector or
pulling cable 4 out of the ignition coils, may be performed at starting speed or when the engine is running.
Every high voltage circuit must be loaded with at least 2 k (spark plug connector).
If it is necessary to test the ignition spark when providing roadside assistance, this must only be done with a spark plug at a cylinder ignition cable. Ensure that spark plug has good contact to ground.
Before working at cranking speed, e.g. checking compression pressure, switch off ignition and disconnect connector "2" from control unit.
Engine 120 has two injection/ignition systems.
Use of testing units
Only connect and disconnect secondary measuring sensor to corresponding ignition cables when vertical engine and ignition are switched off.
If the short-circuit protection is operated (cylinder comparison) and the engine stays upright, it is not possible to conduct the test with this test instrument.
