Diagram 1
WARNING: This vehicle is fitted with a supplemental restraint system (SRS) consisting of a combination of driver (and
passenger) airbag(s), side impact protection airbags and seatbelt pre-tensioners. The use of electrical test equipment
on any SRS wiring systems may cause the seatbelt pre-tensioners to abruptly retract and airbags to explosively deploy,
resulting in potentially severe personal injury. Extreme care should be taken to correctly identify any circuits to be
tested to avoid choosing any of the SRS wiring in error.
For further information see airbag system precautions in body electrical systems chapter.
Note: The SRS wiring harness can normally be identified by yellow and/or orange harness or harness connectors.
