1. Check the No. 25 METER (7.5 A) fuse in the under-
dash fuse/relay box before testing.
2. Park the vehicle on level ground.
@ Do not smoke while working on the
fuel system. Keep open flame away trom the work
aroa. Drain fuel only into an approved container.
Drain the fuel into an aoDroved container. Then
install the drain bolt with a new washer.
Add less than 8 f (2.1 U.S. Gal. 1.8 lmp. Gal) of fuel,
and turn the ignition switch ON {ll). The low fuel indi-
cator light should come on within four minutes.

. lf the light comes on within four minutes, go tostep 8.
. lf the light does not come on within four min-
utes. go to step 5.
Remove the seat cushion (see section 20).
Remove the fuel tank access panel from the floor,
and disconnect the 5P connector from the fuel pump,
Connect the No. 1 and No. 2 terminals with a jumper
wire.
. lf the lightcomeson, checkthe sending unit.. lf the light does not come on, check for:- an open in the GRN/yEL wire between thefuel unit and fuel gauge assembly.- blown bulb.- poor ground (G552).

Troubleshooting Procedures
Checking ths Diagnostic Trouble Code (DTC)
with an O8D ll Scan tool or Honda PGM Tsster
When the PCM senses an abnormality in the input or output systems, the El ('97 - 98) or E ('99 - O0) indicator light in thegauge ass€mbly will blink. When the 16P Data Link Connector (DLC) {located under the dash on the passenger's side) is
connected to the OBD ll Scan Tool or Honda PGM Tester as shown, the scan tool or tester will indicate the Diagnostic
Trouble Code (DTC) when the ignition switch is turned ON(ll).
HONDA PGM TESTER olOBD II SCAN TOOL
lf the E or E indicator light or the MIL has been reported on, or if a driveability problem is suspected, follow this proce-
dure:
1. Connect the OBD ll Scan Tool (conforming to SAE J1978) or Honda PGM Tester to the 16P DLC. (See the OBD ll ScanTool or Honda PGM Tester user's manual for specific instructions. lf you are using the Honda PGM Tester, make sureit is set to the SAE DTC Wpe).2. Turn the ignition switch ON (ll), and observe the DTC on the screen
3. Record allfuel and emission DTCS, A,,/T DTCS, and freeze data.
4. lf there is a fuel and emissions DTC, first check the fuel and emissions system as indicated by the DTC (except for DTCP0700). DTC P0700 means there is one or more Ay'T DTC, and no Droblems were detected in the fuel and emissionscircuit of the PCM.
5. Wire down the radio station presets.
6. Reset the memory with the PGM Tester o. by removing the BACK UP fuse in the under-hood fuse/relay box for morethan 10 seconds.
7. Drive the vehicle for several minutes at speeds over 30 mph (50 km/hr), and then recheck for DTCS. lf the A/T DTCreturns, 9o to the Symptom-to Component Chart on pages 14-60 and 14-61 for the '97 models, and pages 14-62 and14-63 for '98 - 00 models. lf the OTC does not return, there was an intermittent problem within the circuit. Make sureall pins and terminals in the circuit are tight, and then go to step 8.8. Reset the radio Dreset stations, and set the clock.
