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.

Checking the Diagnostic Trouble Code IDTCI
with the Servic€ Check Connestol and Special Tool
when the PcM senses an abnormality in the input or output systems' the E ('97 - 98) or E (gS - OO) indicator light in the
gauge assembly may blink.
When the Service Check Connector (2P) (located under the dash on the passenger side) is connected with the special tool
as shown, the E or E indicator light will blink the Diagnostic Trouble Code (DTC) when the ignition switch is turned ON
{ ).
when the E or E indicator light has been reponed on, connect the service check connector (2P) to the special tool
Then turn ON (ll) the ignition switch and observe the E or 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 short
blinks. one long blink equals 1o 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 14-60 and 14-61 for the '97 model,
and pages 14-62 and 14-63 tor the '98 - 00 models.

L Remove the kick panel on the passenger's side (see section 2O),
2. Remove the PCM, and turn it over.
Inspect the circuit on the PCM according to the troubleshooting flowchart with the special tools and a digital multime-ter.
How to Use the Backplobe Set

PCM Reset Procedure
'1. Turn the ignition switch off
2. Remove the BACK UP fuse (7.5 A) from the under-hood fuse/relay box for 10 seconds to reset the PCM.
NOTE:
. Disconnecting the BACK Up fuse also cancels the radio preset stations and clock setting Make note of the radio
presets before removing the fuse so you can reset them
. The PCM memorv can also be cleared by using the OBD ll Scan Tool or Honda PGM Tester'
UNDER.HOODFUSE/RELAY BOX
Final Proceduro
This procedure must be done after any troubleshooting.
1. Turn the ignition switch OFF.
2. Reset the PCM.
3. Disconnect the OBD ll Scan Tool or Honda PGM Tester from the Data Link Connector (16P), or remove the special tool
from the Service Check Connector (2P).
4. Turn the ignition switch ON (ll), and set the radio presets and clock setting'
5, To verify that the problem is repaired. test-drive the vehicle for several minutes at speeds over 30 mph (48 km/h).
