DESCRIPTION
The meter CPU uses the fuel sender gauge assembly to determine the level of the fuel in the fuel tank. The resistance of the fuel sender gauge will vary between approximately 13.5 Ω with the float at the full position, and 414.5 Ω with the float at the empty position. The meter outputs battery voltage through two 820 Ω resistors that are mounted in parallel inside the meter CPU. The meter CPU measures the voltage between the variable resistor in the fuel sender gauge and the two resistors mounted in parallel in the meter. Voltage measured at this point will vary as the float of the fuel sender gauge is moved. The highest voltage observed should be approximately half of the battery voltage.

While Alarm is Armed, Battery is Reconnected but Alarm does not Sound
DESCRIPTION
While the alarm is armed, the EEPROM inside the main body ECU (multiplex network
body ECU) will remember the armed state even if the battery is disconnected, and
the alarm will sound when the battery is reconnected.
If the alarm does not sound when the battery is reconnected, the a ...
