6. ARCTIC HEATER FAULT CODE RETRIEVAL DEVICE (FCRD) OPERATION (MODEL B).
The Fault Code Retrieval Device (FCRD) is used to troubleshoot and isolate component
failures in the arctic heater (Model B) system.
The Fault Code Retrieval Device (FCRD) reads, displays, and deletes fault codes stored in
the arctic engine heater control unit. The FCRD saves up to 5 fault codes, stored in the
arctic engine heater electronic control unit memory, labeled F1 to F5. The latest fault code
recorded is labeled F1.
The current or present fault code is labeled "AF" and is always stored in the F1 memory
location. Previous fault codes are transferred to memory locations F2 to F5.
Refer to MALFUNCTION 9, ARCTIC HEATER DIAGNOSTIC TROUBLESHOOTING to
troubleshoot diagnostic codes for the arctic heater (Model B).
