Vehicle Overview
Notice: This external clean air reference is obtained by way of
the oxygen sensor signal and heater wires. Any attempt to
repair the wires, connectors, or terminals could result in the
obstruction of the air reference and degraded sensor
performance.
Notice: The following guidelines should be used when servicing
the heated oxygen sensor:
– Do not apply contact cleaner or other materials to the
sensor or vehicle harness connectors. These materials
may get into the sensor causing poor performance.
–
Do not damage the sensor pigtail and harness wires in such
a way that the wires inside are exposed. This could provide
a path for foreign materials to enter the sensor and cause
performance problems.
– Ensure the sensor or vehicle lead wires are not bent sharply
or kinked. Sharp bends or kinks could block the reference
air path through the lead wire.
– Ensure that the peripheral seal remains intact on the
vehicle harness connector in order to prevent damage due
to water intrusion.
Ignition OFF When Disconnecting Battery
Notice
Notice: Always turn the ignition OFF when connecting or
disconnecting battery cables, battery chargers, or jumper
cables. Failing to do so may damage the Power Train Control
Module (PCM) or other electronic components.
Installing Hoses without Twists or Bends Notice
Notice: The inlet and outlet hoses must not be twisted during
installation. Do not bend or distort the inlet or outlet hoses to
make installation easier. Failure to follow these procedures
could result in component damage.
Machined Surface Damage Notice
Notice: Do not nick, scratch or damage the sealing surface. The
sealing surface is a machined surface. Damage to the
machined surface can cause leakage.
Power Train Control Module and Electrostatic
Discharge Notice
Notice: Do not touch the connector pins or soldered
components on the circuit board in order to prevent possible
electrostatic discharge (ESD) damage to the PCM.
Warnings and Notices
Power Steering Hose Disconnected Notice
Notice: Do not start the vehicle with any power steering gear
inlet or outlet hoses disconnected. When disconnected, plug or
cap all openings of components. Failure to do so could result
in contamination or loss of power steering fluid and damage to
the system.
Ring Gear Removal Notice
Notice: Do not pry the ring gear from the differential case.
Prying the ring gear from the differential case may cause
damage to the ring gear and/or the differential case.
Sealant Notice
Notice: Do not allow the RTV sealant to enter any blind
threaded hole. RTV sealant that is allowed to enter a blind
threaded hole can cause hydraulic lock of the fastener when
the fastener is tightened. Hydraulic lock of a fastener can lead
to damage to the fastener and/or the components. Hydraulic
lock of a fastener can also prevent the proper clamping loads
to be obtained when the fastener is tightened. Improper
clamping loads can prevent proper sealing of the components
allowing leakage to occur. Preventing proper fastener
tightening can allow the components to loosen or separate
leading to extensive engine damage.
Scan Tool Usage Notice
Notice: Before perform vehicle diagnostic, pay attention to the
following, otherwise it may cause damage to the engine control
module.
– The scan tool and the software must be up to date.
– Vehicle battery must be fully charged, battery voltage
should be between 12-14 V.
– Scan tool terminals must be firmly connected.
– When programming the engine control module, do not
connect the battery to the charger.
Steering Wheel in the Full Turn Position Notice
Notice: Do not hold the steering wheel in the full turn position
longer than 5 seconds, as damage to the steering pump may
result.
