Disconnecting and reconnecting battery |
When recharging or jump starting vehicles with start/stop system, note the following: first connect charging cable to battery positive terminal, then body earth. This ensures that the battery sensor is not bridged. The direct charging of the battery on the negative terminal clamp means that the battery sensor is shunted and the battery data are not registered by the sensor while charging. The values concerning the battery state saved in the data bus diagnostic interface do not then correspond to the values of the charged battery. |
