Maintenance tips:
The malfunction has been confirmed, and the
following problems may possibly exist
1) The power generator already damaged
and failed for power generation
2) Generator excitation circuit open
Maintenance tips:
The malfunction is not ultimately confirmed and it may
possibly be a random malfunction. Inspect the following
items:
1) Inspect the generation capacity of power generator
(voltage of generator to be measured after startup)
84. P0563 System Battery Voltage too High
Description about Malfunction Cause:
After engine has been started, ECU performs continuous monitoring over the voltage of battery, and the
system will determine the voltage of battery to be too high, when if is found that the battery voltage is h
higher than the upper limit set by the system.
