DANGER

•

In order to avoid injury to yourself or others from 
accidental deployment of the air bag during servic-
ing, read and carefully follow all the precautions 
and procedures described in this manual.

•

After disconnecting the battery cable, wait 60 sec-
onds or more before proceeding with the following 
work. The SRS system is designed to retain 
enough voltage to deploy the air bag for a short 
time even after the battery has been disconnected, 
so serious injury may result from unintended air 
bag deployment if work is done on the SRS system 
immediately after the battery cables are discon-
nected.

•

The SRS-ECU adopts the rollover specification 
that the curtain airbag and seat belt pre-tensioner 
operate at the occurrence of rollover. Therefore, do 
not tilt the vehicle to the right and left with the IG 
ON or tilt the SRS-ECU to the right and left with the 
IG ON and the harness installed.

WARNING

•

Battery posts, terminals and related accessories 
contain lead and lead compounds. WASH HANDS 
AFTER HANDLING.

•

Certain components of this vehicle, such as air 
bag modules and seat belt pre-tensioners, may 
contain perchlorate materials. Special handling 
may apply. For additional information, see 
www.dtsc.ca.gov/hazardouswaste/perchlorate.

•

Do not use any electrical test equipment on or near 
the SRS components, except those specified on 

P.52B-423

.

•

Never Attempt to Repair the Following Compo-
nents: SRS-ECU, Clock Spring, Air Bag Module, 
Front impact sensor, Side Impact Sensor, Seat Belt 
with Pre-tensioner, Seat slide sensor, Front seat 
assembly. If any of these components are diag-
nosed as faulty, they should only be replaced, in
