Inspection
1. INSPECT FRONT DIFFERENTIAL
(a) Using a dial indicator, measure the backlash of one
pinion gear while holding the front differential side
gear toward the case.
Standard backlash:
0.05 - 0.2 ...

Inspection
1. Inspect no. 3 Intake air control valve
assembly
(A) inspect actuator operation.
(1) With 26.7 Kpa (200 mm hg, 7.9 In. Hg) of
vacuum applied to the actuator, check that the
actuator rod moves.
(2) One minute after applying the vacuum, check
that the actuator rod does not return.

Calibrating the compass
The direction display deviates from the true direction determined by
the earth’s magnetic field. The amount of deviation varies according to
the geographic position of the vehicle.
If you cross over a map boundary shown in illustration, the compass will
deviate.
To obtain higher preci ...
Mute Signal Circuit between Radio and Navigation Assembly and
Television Display Assembly
DESCRIPTION
The radio and navigation assembly controls the volume according to the MUTE
signal from the television
display assembly.
The MUTE signal is sent to reduce noise and a popping sound generated when
switching the mode, etc.
If there is an open in the circuit, noise can be heard ...
