3. Check that the hole in the adiuster is perfectly aligned
with the hole in the shift cable. There are two holes in
the adjuster. They are positioned 90" apart to allow
cable adjustment in 1/4 turn increments.
lf the hole is not perfectly aligned, loosen the lock-
nut on the adjuster and adjust as required.
Tighten rhe locknut to 7 N.m (0.7 kgim,5 lbf'ft).
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 in the adiuster
securery.
lMove the shift lever to each position, and verify that
the shift position indicator follows the automatlc
transaxle gear position switch.
Start the engine, and check the shift lever in all
positions. lf any gear does not work properly, refer
to troubleshooting (see page 14-294 and 14-295).
Insert the ignition key into the key cylinder on the
Aff gear position indicator panel, and verify that the
shift lock lever is released.

NOTE:
. Make sure the steering joint is connected as follows:
a. Insert the upper end of the steering ioint onto the
steering shaft (line up the bolt hole with the flat on
the shait), and loosely install the upper joint bolt.
b. Slip the lower end of the steering joint onto the
pinion shaft (line up the bolt hole with the groove
around the shaft), and loosely install the lower
joint bolt.
Be sure that the lowei joint bolt is securely in the
groove in the pinion shaft.
c. Pull on the steering joint to make sure that the
steering joint js fully seated. Then tighten the ioint
bolts.
. 8e sure the wires are not caught or pinched by any
parts when installing the column
. Make sure the wire harness is routed and fastened
properly.
. Make sure the connectors are properly connected.

Troubleshooting Precautions
ABS Indicator Light
I The ABS indicator light comes on when the ABS control unit detects a problem in the system. However, even thoughthe system is normal, the ABs indicator light can come on, too, under the following conditions. To determine theactual cause of the problem, question the customer about the problem, taking the following conditions into consider-ation.
. Signal disturbance
. Wheel soin
. Only drive wheels rotate. Battery voltage fluctuates
2. When a problem is detected and the ABS indicator light comes on, the indicator light can stay on untat the ignitionswitch is turned off, or it can automatically go off, depending on the mode.. Lightstayson until the ignition switch isturned off;When the system is inthesvstem down mode.o Light automatically goes off:When the system is in the control inhibition mode.(refer to symptom-to-system chart)3 The ABS indicator light stays on when the system is reactivated without erasing the DTC, but it goes off after startingthe car.
when the wheel sensor system is faulty and the ABS indicator light comes on, the algorithm of the system automaticallyturns off the ABS indicator light after the wheel speed signal returns to the normal speed. while, when the DTC is erased,the CPU is reset and the ABS indicator light goes off when the system check€d out normal by the initial diagnosis.Therefore, test-drive the car after servicing the wheel sensor system, and be sure that the ABS indicator light does notcome on.
4. When the ABS control unit outputs battery voltage to the gauge assembty, the ABS indicator light goes off.
Diagnostic Trouble Code (DTC)
1. The diagnostic trouble code (DTC) is memorized when a problem is detected and the ABS indicator light does not gooff, or when the ABS indicator light comes on.The DTC is not memorized when the ABs indicator right 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 later 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 thev 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 orocedures toerase.
Solf-diagnosis
1. The self-diagnosis can be classifield into these four categories:' Initial diagnosis; Performed right after the engine sta rts and untiltheABs indicator light goes off.o 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 light is ON.2 The system performs the following controls when a problem is detected by the self-diagnosis:. ABS indicator light ON. Memory of DTC
