The following components of the air bag systems are monitored by a diagnostic system:
• Crash sensors, and diagnostic module (SAS
unit)
• Front air bag sensors
• Air bag modules
• Side crash sensors
• Air bag/Front seat belt pretensioner system
warning light
• Front seat belt pretensioners
• Related wiring
(With Driver and Front Passenger Occupant Classification System)
• Front passenger air bag deactivation indicator
light
• Driver seat slide position sensor
• Front passenger seat weight sensors
• Front passenger seat weight sensor control
module
• Front passenger seat belt buckle switches
The diagnostic module continuously monitors the system's readiness. This begins when the ignition is switched ON and continues while the vehicle is being driven.

Outline
Electrical brake assist control has been adopted, improving safety.
The DSC HU/CM, integrating both the hydraulic unit (HU) and control module
(CM), has been adopted, resulting in a size and weight reduction.

Crankshaft Position (CKP) Sensor Inspection
Visual Inspection
CAUTION:
When foreign material such as an iron chip is on the CKP sensor, it can cause
abnormal output from the sensor because of flux turbulence and adversely affect
the engine control. Be sure there is no foreign material on the CKP sensor when
replacing.
