1. Disconnect from the electronic block located under the main cylinder of brakes (V6 engine), the socket and execute the following checks, being guided by the scheme (see subsection 12.2.2.) |
| 2. Check presence of tension of the battery on a conclusion of the 9th socket. |
| 3. Check presence of voltage of 5 V on a conclusion 4 sockets. If there is no tension, then take the processor block to repare. |
| 4. Check presence of the fluctuating tension 0,1-4,5 B on conclusions 5, 6 and 7 sockets (for this purpose ask the assistant to include a starter). If there is no tension, then take the processor block to repare. |
| 5. Check reliability of connection weighing conclusion 3. |
| 6. If checks yielded positive result, then disconnect sockets on each coil and check existence of a signal by means of a light-emitting diode (see subsection 3.4.5.). If the signal is, then check integrity of a chain from the ignition block to the coil. If the chain is serviceable, then replace the block of ignition. |
