Faults
Gen 4 and Gen 5 controllers report fault code information differently.
Generation 4 controllers
store
all detected fault codes and report them one
code at a time. Brake-Link™ offers an option for viewing the stored fault and
clearing faults from the ECU.
✔
View the stored fault screen
(pg. 77)
.
✔
Clear the fault codes from the ECU
(pg. 80)
. If the cleared code appears
again, it’s active.
✔
Repair the system and clear faults again to ensure that the repair reme-
died the fault code.
Generation 5 controllers differentiate between active and historical fault codes.
Active fault code appear in the
Existing Fault Code List
, while historical fault
codes appear in the
Stored Fault Code List
. Once you repair a problem, the
ECU moves the associated fault code to the stored list for future reference.
✔
Review existing codes
(pg. 75)
; then, review fault history in the stored list
(pg. 77)
. Both lists display up to 16 codes.
✔
Repair the vehicle.
✔
Clear the fault codes
(pg. 80)
before cycling power or road testing. A
code that appears in the stored list
only,
after cycling power or road test-
ing the vehicle, indicates an intermittent problem.
