NOTE: The preferred method is to use the HDS to
retrieve the P-code.
When the PCM senses an abnormality in the input or
output system, the D indicator (A) in the gauge control
module (B) will usually blink.
When the D indicator has been reported on, connect the
HDS to the DLC (A) located behind the driver’s
dashboard lower cover. Turn the ignition switch to
ON (II), select SCS mode, then the D indicator will
indicate flash the DTC.
If the D indicator and the MIL come on at the same time,
or if a driveability problem is suspected, do this:
1. Connect the HDS to the DLC. (See the HDS user’s
manual for specific instructions.)
2. Turn the ignition switch to ON (II), select SCS mode,
then observe the D indicator in the gauge control
module. Codes 1 through 9 are indicated by
individual short blinks. Code 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 which 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 indicated DTC’s troubleshooting.
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.
