How to Check for DTCs with the SCS Mode
(retrieving the flash codes)
When the PCM senses an abnormality in the input or
output system, the D4 indicator (A) in the gauge
assembly (B) will usually blink.
When the D4 indicator has been reported on, connect
the HDS to the DLC (A) (located under the steering
column lower cover). Turn the ignition switch ON (II),
select Honda System, and SCS mode, then the D4
indicator will indicate the DTC.

If the D4 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 Honda
System, and then SCS mode, then observe the D4
indicator in the gauge assembly.
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, 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.
NOTE: You can also reset the memory by removing
the No. 13 fuse in the passenger's under-dash fuse/
relay box for more than 10 seconds. If you do, you
need to do the following:
• Get the customer's radio and navigation (if
equipped) anti-theft code, and write down the
radio and navigation presets.
• Enter the radio and navigation (if equipped) anti-
theft code, reset the preset stations, and set the
clock.
• Do the idle learn procedure (see page 11-202).
6. Drive the vehicle for several minutes under the
same conditions as those indicated by the freeze
data or at speeds over 30 mph (50 km/h), 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.
