• 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
