When the PCM senses an abnormality in the input or
output system, the D indicator (A) in the gauge
assembly (B) will usually blink.
When the D indicator has been reported on, connect the
HDS to the DLC (A) (located under the dash behind the
center console). Turn the ignition switch ON (II), select
SCS mode, then the D indicator will indicate (blink) the
DTC.
If the D indicator and the MIL come on at the same time,
or if a driveability problem is suspected, follow this
procedure:
1. Connect the HDS to the DLC. (See the HDS user’s
manual for specific instructions.)
2. Turn the ignition switch ON (II), select SCS mode,
then observe the D indicator in the gauge assembly.
Codes 1 through 9 are indicated by individual short
blinks. Codes 10 and above are indicated by a
series of long and short blinks. One long blink
equals 10 short blinks. Add the long and short
blinks together to determine the code.
3. Record all fuel and emissions DTCs and A/T DTCs.
4. If there is a fuel and emissions DTC, first check the
fuel and emissions system as indicated by the DTC
(except DTC 70, DTC 70 means there is one or more
A/T DTCs, and no problems were 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 DTC. If the A/T DTC
returns, go to the DTC troubleshooting index. If the
DTC does not return, there was an intermittent
problem within the circuit. Make sure all pins and
terminals in the circuit are tight.
