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.

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.

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.

Battery
a Battery fluid (electrolytel contains sulfuric acid. lt may causo severe burns if it gsts on yout skin or in your eyes.Wear piotective clothing and a face shield.- ll electrolyte gets on your skin or clothes, rinse it ofl with water immediately.- lf electlolyte gets in your eyes, tlush it out by splashing water in your eyes for at least 15 minutes; call a physicianimmediately.
a A battery gives off hydlogen gas. lf ignited, the hydrogen will explode and could crack the battery case and splatte.acid on you. K6ep sparks, flames, and cigarettes away from the battery.a Overchalging will raisc the temperatulg of the electrolyte. This may force electrolyte to spray out ol the battery vents.Follow the chatge. manutacturer's instructions and charge the baftely at a ptope. rate.
NOTE: The original radio has a coded theft protection circuit. lf service to the car requires any of the tollowing, be sureto get the customer's code number before- disconnecting the battery.- removing No. 47 (7.5 A) fuse from the under-hood fuse/relay box.- removing the radio.
After service, reconnect power to the radio and turn it on. When the word "CODE" is displayed, enter tne customer's5-digit code to restore radio operation,
Use either a JCI or Bear ARBST tester, and follow the manufacturer's procedures. lf you don't have one of these com-puterazed testers, follow this conventional test Drocedure:To get accurate results, the temperature of the electrolyte must be between 70'F {21oC} and IOOoF (38oC).
lf the case is cracked or the posts are loose,
reDlace the batterv.
lf the indicator shows low electrolyte, add
distilled water if possible.
Test Load Capacity (# 1l
. Apply 3O0 amp load for 15 seconds to remove
surface charge.. Allow 15 seconds recovery period.. Apply test load {see Test Load Chart).. Record voltage at the end of l5 seconds.
Voltage stays above 9.6
volts: The battery is OK.

Circuit ldentification for In'Line and Fuse Box Connectors
tuse the chart (on page 204, sample below) to help diagnose multiple symptoms in separate
circuits which could be caused by a single problem in a connect,oishared by those circuits'
Here's how that chart could help you find such a problem:
1. Pick one of the multiple symptoms and look up the schematic for that circuit'
2. Make a list of all in-lrne and fuse box connectors in that schematic (include page numbers).
3. Then, in the chart, look up each connector on your list to see if circuits related to the other
symptoms run through one of them. lf they do, inspect that connector for the problem.
Example: The horn, A,/C, and the right headlight don't work. List all in-line and fuse box
connectors in the horn circuit and then check the chart (sample below). You find that C211 is
common to the A,/C circuit and the headlight circuit, so you inspect c211 and find the problem:
bent terminals.
