Fault/Error Codes

Refer to customer fault/error codes below and service fault/
error codes on page 5-6.

Fault codes are displayed by alternately showing F# and E#. All
fault codes have an F# and an E#. The F# indicates the suspect
System/Category. The E# indicates the suspect Component
system.
Up to four Fault/Error codes may be stored. When the oldest
fault code is displayed, additional presses of the 3rd button
