AIRBAG SENSOR ASSEMBLY
(1)
Never reuse an airbag sensor assembly that has been involved in a collision where the SRS has
deployed.
(2)
The connectors to the airbag sensor assembly should be connected or disconnected with the
sensor mounted on the floor. If the connectors are connected or disconnected while the airbag
sensor assembly is not mounted on the floor, the SRS may activate.
(3)
Work must be started at least 90 seconds after the ignition switch is turned OFF and the cable
from the negative (--) battery terminal is disconnected, even if only loosening the set bolts of the
airbag sensor assembly.
(i)
WIRE HARNESS AND CONNECTOR
(1)
The SRS wire harness is integrated with the instrument panel wire harness assembly. All the con-
nectors in the system are a standard yellow color. If the SRS wire harness becomes discon-
nected or the connector becomes broken, repair or replace it.
3.
ELECTRONIC CONTROL
(a)
REMOVAL AND INSTALLATION OF BATTERY CABLE
(1)
Before performing electronic work, disconnect
cable from the negative (--) battery terminal to pre-
vent component and wire damage caused by acci-
dental short circuits.
(2)
When disconnecting the terminal cable, turn the
ignition switch and headlamp dimmer switch OFF
and loosen the terminal nut completely. Perform
these operations without twisting or prying the ter-
minal. Remove the battery cable from the battery
terminal.
(3)
Clock settings, radio settings, audio system
memory, DTCs and other data are erased when the
battery cable is disconnected. Write down any nec-
essary data before disconnecting the battery cable.
(b)
HANDLING OF ELECTRONIC PARTS
(1)
Do not open the cover or case of the ECU unless
absolutely necessary. If the IC terminals are
touched, the IC may be rendered inoperative by
static electricity.
(2)
Do not pull the wires when disconnecting electronic
connectors. Pull the connector itself.
(3)
Be careful not to drop electronic components, such
as sensors or relays. If they are dropped on a hard
surface, they should be replaced.
(4)
When cleaning the engine with steam, protect the
electronic components, air filter and emission--re-
lated components from water.
(5)
Never use an impact wrench to remove or install
temperature switches or temperature sensors.
