(25) Battery Voltage Abnormality (DTC P0562 / 168-4, P0563 / 168-3)

P0562 / 168-4: Battery voltage abnormality (Low side)
Behaviour during malfunction:
• Faulty starting
• Insufficient output
• Worsening exhaust gas performance
• Engine stops in some case
Detection item:
• Open circuit, short circuit or damage of harness
• Failure of battery
DTC set preconditions:
• Key switch is ON
• Starter Switch signal (ECU: B-54 terminal) is not activated
DTC set parameter:
• ECU recognition of battery voltage is below 8 V in 12 V system (ECU data value: 0.9615)
Engine warning light:
• ON
System action:
• Output limitation: Approximately 50 % of normal condition
• Speed limitation (Accelerator limitation: 50 %)
• EGR stop
• Intake throttle 100 % open
• Only main injection permitted
Recovery from error:
• Diagnostic counter = zero
