How to Clear Codes in a 95 E320

1. Locate the battery, which is under the rear passenger seat. To remove the seat, turn the clips on the seat until it can easily be lifted out of place.
2. Identify the negative battery cable, which will be black and marked with a minus sign.
3. Disconnect the clamp holding on the negative cable by using the adjustable wrench to loosen the bolt until the clamp can be removed.
4. Wait at least 30 seconds.
5. Reconnect the negative battery clamp on the battery terminal and tighten until the clamp is secure.
6. Start the vehicle to confirm the check engine light has gone off, indicating the codes have been cleared.
7. Reinstall the rear seat.
