Diagnostic Trouble codes (DTc) are
error codes that appear when there
is a problem with your vehicle. If your
vehicle displays a check engine light,
DTC’s will be available to assist in
diagnosing the problem. You can use
the PowerPDA to run a vehicle system
check and display these DTc(s). A
code will be given along with a brief
description of the problem, a full
description of the code will display in
a pop up window when the code is
highlighted. You may reference your
vehicle service manual for description
and possible corrective action to fix
the problem. Once the problem has
been repaired you can clear the code
to turn the check engine light off.
Note: Keep a written record of the DTC
code(s) that display on your PowerPDA
for future reference before clearing
them.
Check for OBD II DTC
If any vehicle DTc(s) are present,
troubleshoot/repair the cause. Once
the cause is properly remedied, touch
‘Clear Codes’ and then ‘Check for
Codes’ again to verify the problem
is fixed (the ODB ll code should not
re-appear).
1.
Press the center button on the
5-way navigator to take you to the
System Menu screen. See Figure 4.
2.
Next, touch the ‘OBD II Codes’
button.
3.
With the ignition in the on/run
position or with the engine running,
touch the button labeled ‘check For
Codes’. See Figure 9.
Note: The Banks SpeedBrake
PowerPDA will check for vehicle
diagnostic codes and display either
the p-code with a brief description of
the code or the message “Done! – No
Codes Present”. For a full description
of the code, highlight the code and a
window will pop up with a detailed
explanation.
4.
To return to the System Menu
touch ‘<Back’. If DTC were found and
you would like to clear them, proceed
to step 5.
Clearing OBD II DTC
5.
After checking for and reviewing
any DTC problem, touch ‘Clear Codes’
to erase them from the vehicle EcU.
If multiple codes are present and the
underlying problem has been fixed,
they will all be cleared.
Note: To clear codes the ignition key
must be in the On/Run position, but
the engine must NOT be running. If the
engine is running, Banks SpeedBrake
PowerPDA will display a pop-up
message instructing you to check the
ignition key is in the ON position.
6.
Press ’Check For Codes’ again to
verify the OBD II codes were erased.
Some status monitor codes require a
certain amount of engine “run time” in
order to be cleared.
7.
If diagnostic codes reoccur on your
vehicle, you should investigate the
underlying problem to correct it.
