times by increasing injector pulse width accordingly.
NOTE: Never apply battery voltage directly across a low resistance
injector. This will cause injector damage from solenoid coil
overheating.
Fig. 1: Injector Driver Types - Current and Voltage
CURRENT CONTROLLED CIRCUIT ("PEAK & HOLD")
The current controlled driver inside the computer is more
complex than a voltage controlled driver because as the name implies,
it has to limit current flow in addition to its ON-OFF switching
function. Recall, this driver typically requires injector circuits
with a total leg resistance of less than 12 ohms.
Once the driver is turned ON, it will not limit current flow
until enough time has passed for the injector pintle to open. This
period is preset by the particular manufacturer/system based on the
amount of current flow needed to open their injector. This is
typically between two and six amps. Some manufacturers refer to this

WHEEL ALIGNMENT PROCEDURES
CAMBER ADJUSTMENT
Except Montero, Montero Sport & 3000GT
Camber is preset and cannot be adjusted. Check camber. See
appropriate table under WHEEL ALIGNMENT SPECIFICATIONS . If camber is
not within specification, replace damaged or bent parts.
Montero & Montero Sport
1) Check camber. See appropriate table under
WHEEL ALIGNMENT SPECIFICATIONS . If camber is not within specification,
remove shock absorber mounting nut and lock nut.
CAUTION: Difference in shim thickness between front and rear must not
exceed 0.16" (4.0 mm). DO NOT use more than 3 shims at
onelocation.
2) Compress shock absorber, and loosen upper arm mounting
bolts and nuts. Adjust camber by increasing or decreasing shims
between upper arm shaft and crossmember. See Fig. 6.

Similar)

3000GT
Check camber. See WHEEL ALIGNMENT SPECIFICATIONS (3000GT)
table. If camber is not within specification, loosen eccentric cam
nut. Rotate eccentric cam bolt to obtain correct camber. See Fig. 7.
Each marking represents a change of .12-.25 degree of camber.
