STABILIZER BAR LINK BALL JOINT
INSPECTION
INSPECT BALL JOINT FOR ROTATION CONDITION
(a) Flip the ball joint stud back and forth 5 times, as shown in the
illustration, before installing the nut.
(b) Using a torque wrench, turn the nut continuously one turn
every 2±4 seconds and take the torque reading on the 5th
turn.
Torque (turning):
0.05±1.0 NVm (0.5±10 kgfVcm, 2.6±8.7 in.Vlbf)
If not within specification, replace the stabilizer bar link. SA±98

Back±Up Function
If there is trouble with the program in the ECM and the ignition signals (IGT) are not output from the microcomput-
er, the ECM controls fuel injection and ignition timing at predetermined levels as a back±up function to make
it possible to continue to operate the vehicle.
Furthermore, the injection duration is calculated from the starting signal (STA) and the throttle position signal
(IDL). Also, the ignition timing is fixed at the initial ignition timing, 10°BTDC, without relation to the engine speed.
HINT: if the engine is controlled by the back±up function, the malfunction indicator lamp lights up to warn the
driver of the malfunction but the diagnostic trouble code is not output. EG±398

DTC 16 A T Control Signal Malfunction
CIRCUIT DESCRIPTION
The signal from the A/T CPU retards the ignition timing of the engine during A/T gear shifting, thus momentarily
reducing torque output of the engine for smooth clutch operation inside the transmission and reduced shift
shock.

If the ECM detects the diagnostic trouble code º16º in memory, it prohibits the torque control of the A/T which
performs smooth gear shifting.
INSPECTION PROCEDURE
Are there any otheer codes (besides Code 16) being output?
Repair engine control module.
Go to relevant diagnostic trouble code chart.
