1A-210 Engine Control System (4HK1)
DTC P0563 (Flash Code 35)
Circuit Description
The ECM monitors the ignition voltage on the ignition
feed terminal to make sure that the voltage stays within
the proper range. If the ECM detects an excessively
high ignition voltage, this DTC will set.
Condition for Running the DTC
• DTC P060B is not set.
• The battery voltage is between 18 to 32 volts.
Condition for Setting the DTC
• The ECM detects that the ignition voltage feed
circuit is more than 32 volts for 30 minutes.
Action Taken When the DTC Sets
• The ECM illuminates the SVS lamp when the
diagnostic runs and fails. Refer to DTC Type
Definitions for Action Taken When the DTC Sets -
Type C. (Euro 4 specification)
• The ECM illuminates the MIL when the diagnostic
runs and fails. Refer to DTC Type Definitions for
Action Taken When the DTC Sets - Type A.
(Except Euro 4 specification)
Condition for Clearing the DTC
• Refer to DTC Type Definitions for Condition for
Clearing the SVS Lamp/ DTC - Type C. (Euro 4
specification)
• Refer to DTC Type Definitions for Condition for
Clearing the MIL/ DTC - Type A. (Except Euro 4
