Verifying Vehicle Repair

Verification of vehicle repair will be more comprehensive
for vehicles with OBD II system diagnostic.  Following a
repair, the technician should perform the following steps:

1. Review and record the Fail Records and/or Freeze

Frame data for the DTC which has been diagnosed
(Freeze Frame data will only be stored for an A or B
type diagnostic and only if the MIL has been
requested).

2. Clear DTC(s).
3. Operate the vehicle within conditions noted in the Fail

Records and/or Freeze Frame data.

4. Monitor the DTC status information for the DTC which

has been diagnosed until the diagnostic test
associated with that DTC runs.

Following these steps are very important in verifying
repairs on OBD systems.  Failure to follow these steps
could result in unnecessary repairs.

Reading Diagnostic Trouble Codes Using
the TECH 2 Scan Tool

The procedure for reading diagnostic trouble code(s) is to
use a diagnostic Scan Tool.  When reading DTC(s),  follow
instructions supplied by tool manufacturer.
For the 1998 model year, Isuzu dealer service
departments will continue to use Tech 2.

Clearing Diagnostic Trouble Codes

IMPORTANT:

Do not clear DTCs unless directed to do

so by the service information provided for each diagnostic
procedure.  When DTCs are cleared, the Freeze Frame
and Failure Record data which may help diagnose an
intermittent fault will also be erased from memory.
If the fault that caused the DTC to be stored into memory
has been corrected, the Diagnostic Executive will begin to
count the “warm-up” cycles with no further faults
detected, the DTC will automatically be cleared from the
PCM memory.

To clear Diagnostic Trouble Codes (DTCs), use the
diagnostic Scan Tool “clear DTCs” or “clear information”
function.  When clearing DTCs follow instructions
supplied by the tool manufacturer.
When a Tech 2 is not available, DTCs can also be cleared
by disconnecting 

one of the following sources for at least

thirty (30) seconds.

NOTE: To prevent system damage, the ignition key must
be “OFF” when disconnecting or reconnecting battery
power.

The negative battery cable.  (Disconnecting the

on-board memory data, such as preset radio tuning).
