CALIBRATION OF DECEL G SENSOR
DescriptionINFOID:0000000006233272
Decel G sensor calibration must be performed when the following operation is performed.
 Removal and installation or replacem ent of yaw rate/side/decel G sensor
 Replacement of A/T assembly
 Replacement of ABS actuator and electric unit (control unit)
CAUTION:
After removing/replacing the yaw rate/side/decal G sensor or replaci ng the ABS actuator and electric
unit (control unit), the decel G sensor of the ABS act uator and electric unit (control unit) must be cali-
brated first. Refer to BRC-66, "
Description".
Special Repair RequirementINFOID:0000000006233273
CAUTION:
After removing/replacing the yaw rate/side/decal G sensor or replaci ng the ABS actuator and electric
unit (control unit), the decel G sensor of the ABS act uator and electric unit (control unit) must be cali-
brated first. Refer to BRC-66, "
Description".
1.PREPARATION BEFORE CALIBRATION PROCEDURE
1. Park the vehicle on a flat road.
2. Adjust pressure in all tires to the specified value. Refer to WT-69, "
Tire Air Pressure".
>> GO TO 2.
2.PERFORM CALIBRATION
With CONSULT-III
1. Turn ignition switch ON. CAUTION:
Never start the engine.
2. Select “G SENSOR CALIBRATION” in “Work Support” in “TRANSMISSION”.
3. Touch “START”. CAUTION:
Never give any motion to the vehicle during the calibration.
Is
“completed” displayed?
YES >> GO TO 3.
NO >> Perform the calibration again.
3.CHECK DTC
With CONSULT-III
1. Turn ignition switch OFF and wait 10 seconds or more.
2. Turn ignition switch ON.
3. Select “Self Diagnostic Results” in “ABS”.
Is
“C1145” or “C1146” detected?
YES >> Refer to BRC-51, "DTC Index".

A/T POSITION
InspectionINFOID:0000000006226794
1. Place selector lever in “P” position, and turn ignition switch ON (engine stop).
2. Check that selector lever can be shifted to other than “P” position when brake pedal is depressed. Also
check that selector lever can be shifted from “P” position only when brake pedal is depressed.
3. Shift the selector lever and check for excessive effort, sticking, noise or rattle.
4. Confirm that the selector lever stops at each pos ition by feeling the engagement when it is moved through
all the positions. Check whether or not the actual pos ition the selector lever matches the position shown
by the shift position indicator and the A/T body.
5. The method of operating the lever to individual positions cor- rectly is shown in the figure.
6. When selector button is pressed in “P”, “R”, or “N” position with-
out applying forward/backward force to selector lever, check but-
ton operation for sticking.
7. Confirm that the back-up lamps illuminate only when lever is placed in the “R” position. Confirm that the back-up lamps do not
illuminate when selector lever is pushed against “R” position in
the “P” or “N” position.
8. Confirm that the engine can only be started with the selector lever in the “P” and “N” positions. (With selector lever in the “P”
position, engine can be started even when selector lever is
moved forward and backward.)
9. Make sure that A/T is locked completely in “P” position.
10. When selector lever is set to manual shift gate, ma ke sure that manual mode is displayed on combination
meter.
In addition, a set shift position must be changed when t he selector lever is shifted to the “+” or “−” side in
the manual mode. (Only while driving.)
AdjustmentINFOID:0000000006379166
1. Shift selector lever in “P” position.
2. Loosen nut (1).
3. Turn the manual lever (2) all the way in the “P” range direction
[ (A)].
4. Hold and push the control cable (3 ) in the vehicle front direction
[ (B)], and tighten the nut by hand with cable set in free condi-
tion.
CAUTION:
Be careful not put any load to manual lever.
NOTE:
Press control cable with a force of 9.8 N (approximately 1 kg, 2.2
lb).
5. Tighten nut to specified torque. Refer to TM-178, "
Exploded View".
