Displaying of Diagnostic Trouble Codes (DTCs)
Stored and active diagnostic trouble codes are output on the instrument panel according to the
J1939 standard as a two-part code as shown on the tables in the Operating Instruction
Section.
Intermittent Fault Diagnostics (with Electronic Controls)
Intermittent faults are problems that periodically "go away". A problem such as a terminal that
intermittently doesn't make contact can cause an intermittent fault. Other intermittent may be
set only under certain operating conditions such as heavy load, extended idle, etc. When
diagnosing intermittent faults, take special note of the condition of wiring and connectors, since
a high percentage of intermittent problems originate here. Check for loose, dirty or
disconnected connectors. Inspect the wiring routing, looking for possible shorts caused by
contact with external parts (for example, rubbing against sharp sheet metal edges). Inspect
the connector vicinity, looking for wires that have pulled out of connectors, poorly positioned
terminals, damaged connectors and corroded or damaged splices and terminals. Look for
broken wires, damaged splices, and wire-to-wire shorts. Use good judgement if component
replacement is thought to be required.
NOTE: The engine control unit (ECU) is the component LEAST likely to
fail.
Suggestions for diagnosing intermittent faults:
•
If the problem is intermittent, try to reproduce the operating conditions that were
present when the diagnostic trouble code (DTC) set.
Observing these values can help determine the operating conditions when the fault occurred.
•
If a faulty connection or wire is suspected to be the cause of the intermittent problem:
clear DTCs, then check the connection or wire by wiggling it while watching the
diagnostic gauge to see if the fault resets.
NOTE: The electronic instrument panel
can have communication problems that
result in Error Codes being shown on its
LCD display window.
EE-Error
ACP-Err
XXXXX-EP
No Data
XXXXX-BO
The following Error Codes all indicate that there is a
communication error with the ECU.
No Addr
ACP-Err
No Data
XXXXX-BR
Contact your servicing dealer for help in correcting these
codes:
