the straight position.
(5) Draw a new line on the masking tape or the
steering wheel as shown in the illustration.
(6) Measure the distance between the 2 lines on
the masking tape of the steering wheel.

(5) Diagnostic circuit
• This circuit constantly diagnoses system
malfunctions. When a malfunction is
detected, it lights up the SRS warning light on
the combination meter assembly to inform the
driver.
(6) Memory circuit
• When a malfunction is detected in the
diagnostic circuit, it is coded and stored in the
memory circuit.
(e) SRS WARNING LIGHT
(1) The SRS warning light is located on the
combination meter assembly. It comes on to
inform the driver of system trouble when a
malfunction is detected in self-diagnosis of the
center airbag sensor assembly. Under normal
operating conditions, when the ignition switch is
turned to the ON position, it comes on for
approximately 6 seconds and then goes off.
