id0802g8080300

Note

• The SRS air bag system can be identified by whether or not the seat track position sensor is present.

― Standard deployment control system: Without seat track position sensor

― Two-step deployment control system: With seat track position sensor

Action for Non-repeatable Malfunction

• If the malfunction does not recur, verify the malfunction cause by performing the following actions:

― Verify that a DTC has been recorded in the memory.

― Based on the repair order form, attempt to drive the vehicle or perform tests to replicate the malfunction, record the data at that time, and detect the malfunction cause.

― Shake the wiring harness or connector of the electrical component which is suspected to be the cause of the malfunction, and inspect for occurrence of any malfunction or DTCs.

― Inspect the female terminals on the connector of the electric component which is suspected to be the cause of the malfunction for poor connection. (See ELECTRICAL SYSTEM.)

Note

• Tool used (Reference): terminal test kit (49US-15-1A0)

Air Bag System Specification Identification

• Because two types of driver and passenger-side air bag module controls, “Two-step deployment control” and “Standard deployment control”, are available depending on when the vehicle was produced, identify the specification referring to the following identification.

Identification

• In this manual, “Two-step deployment control system” or “Standard deployment control system” is used if the service contents differ depending on the control.

• Control is identified by the following components.

Outline

• The OBD (on-board diagnostic) system has the following functions:

― Malfunction detection function: Detects malfunctions in the air bag system and outputs DTCs (Diagnostic Trouble Codes).

― PID/data monitor function: Reads out specific input/output signals and the system status.

• DTCs can be read/cleared using the M-MDS.

Note

• Use the M-MDS to verify DTCs because the DTCs displayed by the air bag system warning light are reference information only.
