General Troubleshooting Information (cont'd)
PGM Tester "SCS" Menu Method (retrieving the flash
codes):
The SRS indicator (A) indicates the OTC by the number
of blinks when the Honda PGM Tester (S) is connected
to the OLC (data link connector) (16P)
(t).
1. Make sure the ignition switch is OFF.
2. Connect the Honda PGM Tester (S) to the OLC (C),
and follow the Tester's prompts in the "SCS" menu
to ground the SCS line (see the Honda PGM Tester
Operator's Manual).
3. Make sure the SCS line is grounded, then turn the
ignition switch ON

The SRS indicator comes on
for about 6 seconds, and then goes off. Then it will
blink to indicate the OTC (see the table below).
4. Read the OTC.
5. Turn the ignition switch OFF, and wait for 10
seconds.
6. Disconnect the Honda PGM Tester from the OLC.
7. Do the troubleshooting procedure for the OTC.
