DCC internal HW error
• Reset DTC • Toggle ignition key to "key off" and await system reset then "key on" i.e. system wake up. • Read out DTC's again • If DTC remains active replace the direct current converter E84.
What you'll see
No driver-visible symptom recorded.
System reaction
• DCC will be disabled and enter error state or reduce the output current to 50% depending on fault. 24V-battery not charging correctly. • Amber warning lamp "Hybrid System Fault" is shown in ICL
Diagnostic depth
One of the following error flags are sent on CAN from DCC: • RAM Error • Internal watchdog reset • External watchdog reset • Heat sink temperature sensor 1 not connected or short circuit • Heat sink temperature sensor 2 not connected or short circuit • All heat sink temp sensors faulty • 15V supply voltage low or high • 5V supply voltage low or high • Minus15V supply voltage low or high • Step up voltage to low • Low side current sensor error • High side current sensor error • Lowside voltage sensor error • EEPROM checksum error in application and CANopen parameter segments • DCC sensor calibration
