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 ...

DTC B1422/22 Compressor Lock Sensor Circuit
SYSTEM DESCRIPTION
The ECM sends an engine speed signal to the A/C amplifier via CAN
communication and BEAN
communication.
The A/C amplifier reads the difference between compressor speed and engine
speed. When the
difference becomes too large, t ...
ACIS Control Circuit
DESCRIPTION
This circuit opens and closes the Intake Air Control Valve (IACV) in response
to changes in the engine
load in order to increase the intake efficiency (ACIS: Acoustic Control
Induction System).
When the engine speed is between 0 and 4450 rpm and the throttle valve opening
angl ...
