Troubleshooting Procedures
Checking the Diagnostic Trouble Code (DTC)
with an OBD ll Scan Tool or th€ Honda PGM Tester
When the TCM senses an abnormality in the input or output systems, the lD,] indicator light in the gauge assembly will
blink. When the 16p Data Link Connector (DLC) (located under the dash on the passenger side) is connected to the OBD ll
Scan Tool or Honda PGM Taster as shown, the scan tool or tester will indicate the Diagnostic Trouble Code (DTC) when
the ignition switch is turned ON {ll}.
When the !r indicator light has been reported on, connect the OBD ll Scan Tool confirming to SAE J1978 or Honda PGM
Tester to the DLC (16P) behind the ashtray. Turn the ignition switch ON (ll) and observe the DTC on the screen ofthe OBD
ll Scan Tool or Honda PGM Tester. After determining the DTC, refer to the electrical system Symptom-to-Component
Chart on pages 14-54 and 14-55.
NOTE: SeetheOBDll ScanTool orHonda PGM Tester user's manual for specific instructions.
OBD-IlSCAN TOOL orHONDA PGM TESTER
Some PGM-Fl problems will also make the lol indicator light come on. After repairing the PGM-Fl system. disconnect the
BACK Up fuse (7.5 A) in the under-hood fuse/relay box for more than 10 seconds to reset the TCM memory, then recheck.
NOTE: Disconnecting the BACK UP fuse also cancels the radio anti-theft code, preset stations and the clock setting. Get
the customer's code number, and make note of the radio presets before removing the fuse so you can reset them

L./Checking th€ Diagnostic Trouble Codo (DTC)
with the Sowica Check Connector and Special Tool
When the TCM senses an abnormality in the input or output systems, the [D;l indicator light in the gauge assembly willblink.
When the Service Check Connector (located under the dash on the passenger side) is connected with the special tool asshown, the E1T indicator light will indicate (blink) the Diagnostic Troubte Code (DTC) when the ignition switch is turned ON{

}.
When the @ indicator light has been reported on, connect the Service Check Connector with the special toot.
GAUGE ASSEMEI.Y
Then turn ON (ll) the ignition switch and observe the E indicator light.Codes 1 through 9 are indicated by individual short blinks. Codes 1O and above are indicated by a series of long and shortblinks. One long blink equals 10 short blinks. Add the long and short blinks together to determine the code. After deter-mining the code, refer to the electrical system Symptom-to-Component Chart on pages 14-S4 and 55.

NOTE: WhentheOBDll Scan Tool orHonda PGM Tester indicates the DTC(S) for the automatic transmission control sys-
tem, the scan tool or tester also indicates code P0700 simultaneously. Code P0700 means detection of some automatic
transmission problem on the PGM-Fl control system.
lf the self-diagnostic E indicator light does not blink. perform an inspection according to the table below.
NOTE:
. lf a custombr describes the symptom for code P1706 (6), P0725 (11) or P0715 (15), it will be necessary to recreate the
symptom by test-driving, then recheck the DTC,. Sometimes the E indicator light and the Malfunction Indicator Lamp (MlL) may come on simultaneously. lf so, check
the PGM-Fl system according to the DTC, then reset the memory by removing the BACK UP fuse in the under-dash
fuse/relay box for more than l0 seconds. Drive the vehicle for several minutes at a speed over 30 mph(50 km/h). then recheck the DTC.
. Disconnecting the BACK UP fuse also cancels the radio anti-theft code, preset stations and the clock setting. Get the
customer's code number, and make note of the radio presets before removing the fuse so you can reset them.
