Notes For Avoiding Damage To Ignition Systems During Testing
- To avoid damage to the control module, disconnect and connect control module connectors with the ignition switched OFF.
- Do not connect a test lamp to circuit 1 or 15 of ignition coil.
- Terminal 1 of the ignition coils must not be short-circuited to grounds, e.g. anti-theft protection.
- Install only original ignition system components.
- Do not operate the ignition system at cranking speed unless the ignition wires are fully connected.
- The following ignition tests should NOT be performed with engine cranking or with the engine running: Holding secondary coil wire at a distance to ground, disconnecting a spark plug connector, or pulling secondary coil wore out of the ignition coil(s).
- Each high voltage circuit must have a load of at least 2 kV (plug connector).
- On the separate ignition coil tests, the ignition coil must not be loaded above 28 kV to avoid damaging the ignition coil.
- If each cuts out when using engine analyzer during cylinder balance test, do not perform further testing with that type of engine analyzer.
- If it is necessary to check the ignition spark following a breakdown, check with spark plug connected to one of the secondary ignition wires. Ensure that the spark plug is well grounded.
- When working at cranking speed, e.g. checking compression, switch off ignition and: On engine with HFM-SFI/ME-SFI fuel injection and ignition system, disconnect connector "2" on control module.
