c) Reconnect the connectors to the ECU. Warning: - Perform all measurements on voltage when connected ¬ ¬ framework of decks or connectors.
• Power battery ba-tarei should not be below 11 when the ignition key. 1. Using a voltmeter with high net resistance (not less
2. Check the chain of diagnosis, if the lamp is not working, the following algorithm, a) If the warning lamp lights up, "CHECK" when the per-bandits, then ground the conclusion 'V on the electronic control unit housing.
- If the lamp is lit, then the pro-Believe wiring between the terminal the electronic control unit "E1" and mass.
