with the hole in the adjusting rod. There are two
holes in the cable adjuster. They are positioned 90"

lf not perfectly aligned, loosen the locknut on the
shitt cable. and adjust as required.
Tighten the locknut.
Install the lock pin on the adjuster. lf you feel the
lock pin binding as you reinstall it, the cable is still
out of adjustment and must be readjusted.
Make sure the lock pin is seated securely in the
adjuster. Replace the lock pin if it does not snap
over the cable adjuster securely.
Move the shift lever to each gear, and verify that the
A/T gear position indicator follows the A"/T gear
position switch.
Start the engine, and check the shift lever in all
gears. lf any gear does not work properly, refer to
troubleshooting on page 14-'153 thru 14-156.
Insert the ignition key into the key cylinder on the
upper column cover, and verify that the shift lock

SUPPLEN\EN AL RES\RA(N SYSTES{ (SRS\
This model has an SRS which includes a driver's airbag in the steering wheel hub. a passenger's airbag in the dashboardabove the glove box ('97 - 00 models), and seat belt tensioners in the seat belt retractors ('98 - 00 models). Informationnecessary to safely service the SRS is included in this Service Manual. ltems marked with an asterisk (*) on the contentspage include, or are located near, SBS components. Servicing. disassembling or replacing these items will require specialprecautions and tools, and should only be done by an authorized Honda oearer.
To avoid rendering the SRS inoperative, which could lead to peFonal iniury or death in the event of a sevore trontalcollision. allSRS service work must be performod by an authorized Honda dealer.lmproper service procedurgs, including incorrect removal and installalion of the SRS, could lead to personal iniurycaused by unintontional deployment of th€ airbags {'97 - 00 models), and seat belt tensioners ('98 - 00 modelsl.Do not bump the SRS unit. Otherwise, the system may lail in case ot a collision, or the airbags may deploy when theignition switch is ON (lll.
SRS electrical wiring harnesses are identitied by yellow colof coding. Ralated components are located in the steeringcolumn, front console, dashboard, dashboard lower panel, and in the dashboard above the glove box. Do not use elec-trical test equipment on these cilcuits,

Troubleshooting Precautions
ABS lndicalor
1 lf the system is oK, the ABS indicator goes off two seconds after turning the ignition switch oN 1l) wathout staningthe engine, and then comes on again and goes off after two seconds. This occurs because the ABS control unit isturned on by the lG2 power source.2. The ABS indicator comes on when the ABS control unit detects a problem in the system. However, even thouoh thesystem is operating properly, the ABs indicator will come on too, under the following conditions:. Signal disturbance
. Wheel spin
. Only drive wheels rotate. Battery voltage fluctuates
To determine the actual cause of the problem, question the customer about the problem, taking these conditions intoconsideration:
3 When a problem is detected and the ABS indicator comes on, the indicator can stay on until the ignition switch isturned OFF, or it can automatically go off, depending on the mode.. Indicator stays on untilthe ignition switch is turned off: When the system is in the system down mode.. Indicator automatically goes off: When the system is in the control inhibition mode.4 The ABS indicator stays on when the system is reactivated without erasing the DTC, but it goes off after starting thevehicle.
When the wheel sensor system is faulty and the ABS indicator comes on. the algorithm of the system automatically turnsoff the ABS indicator after the wheel speed signal returns to the normal speed. Also, when the DTc is erased, the cpu isreset and the ABS indicator goes off when the system checked out normal by the initial diagnosis.Therefore, test-drive the vehicle after servicing the wheel sensor system. and be sure that the ABS indicator does notcome on.
5 When the ABS control unit outputs battery voltage to the gauge assembly, the ABS indicator ooes off.
Diagnostic Trouble Code (DTCI
1. The diagnostic trouble code (DTc) is memorized when a problem is detected and the ABS indicator does not go off,or when the ABS indicator comes on.The DTc is not memorized when the ABS indicator comes on unress the cpu is activated,2 The memory can hold any number of DTCs. However, when the same DTc is detected twice or more, the tater one iswritten over the old one.
Therefore, when the same problem is detected repeatedly, it is recorded as one DTC.3. The DTCs are indicated in the order of ascending number, not in the order they occur.4. The DTCS are memorized in the EEPROM (non-volatile memorv).Therefore, the memorized DTcs cannot be canceled by disconnecting the battery. perform the specified procedures toerase the DTCS.
Self-diagnosis
1. Self-diagnosis can be classified into these four categories:' Initial diagnosis: Performed right after the eng ine starts and untir theABS indicator goes off.. Except ABS control: Performed when the ABS is not functioning.. During ABS control: Performed when the ABS is functioning.. During warning: Performed when the ABS indicator is ON.2. The system performs the fo|owing contrors when a probrem is detected by the serf-diagnosis:. ABS indicator ON. Memorv of DTC. Mode changetothe "system down mode,, or the ,,control inhibition mode,,.
