Advice. In order not to confuse the leads on the ignition coil (ignition module), it is more convenient to change high-voltage wires one by one.
Execution sequence
1. We prepare the car for the operation («Preparing the car for maintenance and repair»).
2. Disconnect the high voltage wires from the spark plugs.
3. Disconnect the tips of the high-voltage wires from the ignition coil.
4. Multimeter (in ohmmeter mode) measure the resistance of the wires.
5. Good wires have resistance (depending on length) should be in the range of 3.5-10.0 kOhm.
Recommendation. The high voltage wires should be replaced as a set.
6. We connect the wires to the spark plugs and the ignition coil in accordance with the serial numbers of the cylinders printed on the wires and on the ignition coil (see below).
Warning. It is only necessary to connect the wires to the ignition coil in accordance with the serial number of the cylinder. The insulation of the wires is marked - the serial number of the cylinder.
