diagnostic trouble code (DTC) w h e n the ignition switch
is turned ON (II) and the appropriate m e n u is selected.
If the D indicator or malfunction indicator lamp (MIL)
has been reported o n , or if a driveability p r o b l e m is
suspected, f o l l o w this procedure:
1. Connect the HDS to the DLC. (See the HDS user's
manual f o r specific instructions.)
2. Turn the ignition switch ON (II), select A/T system,
and observe the DTC in the DTCs MENU on the
HDS screen.
3. Record all fuel and emissions DTCs, and A/T DTCs,
and freeze data.
4. If there is a fuel and emissions DTC, first check the
fuel and emissions system as indicated by the DTC
(except for DTC P0700; DTC P0700 means there is
one or more A/T DTCs, and no problems w e r e
detected in the fuel and emissions circuit of the
PCM).
5. Clear the DTC and data.
6. Drive the vehicle for several minutes under the
same conditions as those indicated by the freeze
data, and then recheck for a DTC. If the A/T DTC
returns, go to the DTC t r o u b l e s h o o t i n g index. If the
DTC does not return, there w a s an intermittent
p r o b l e m w i t h i n the circuit. Make sure all pins and
terminals in the circuit are tight.
