Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"

The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.

Information necessary to service the system safely is included in SUPPLEMENTAL RESTRAINT SYSTEM (SRS) and SEAT BELTS .

UNIFIED METER CONTROL UNIT

1. Speedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled by the unified meter control unit, which is built into the combination meter. Unified meter control unit receives signals from unified meter and A/C amp.
2. Warning lamps and indicator lamps are controlled by signals drawn from the unified meter and A/C amp., BCM (body control module), and components connected directly to the combination meter.
3. Digital meter is adopted for odo/trip meter.* *The record of the odometer is kept even if the battery cable is disconnected. The record of the trip meter is erased when the battery cable is disconnected.
4. Odo/trip meter and A/T indicator segments can be checked in diagnosis mode.
5. Meters/gauges can be checked in diagnosis mode.

Illumination control

The unified meter control unit outputs the odo/trip meter and A/T indicator lighting when the ignition switch is turned ON. When the lighting switch is turned on, the illumination control switch can be used to adjust the brightness of the combination meter illumination and the odo/trip meter illumination. When the ignition switch is in the START position, the combination meter dial lighting and illumination control switch lighting are turned off. For additional combination meter illumination control information, refer to SYSTEM DESCRIPTION .

UNIFIED METER AND A/C AMP.

For unified meter and A/C amp. system description information, refer to SYSTEM DESCRIPTION .

Display Item List

DISPLAY ITEM LIST

Note. Any monitored item that does not match the vehicle being diagnosed is deleted from the display automatically.

*1: Monitor keeps indicating "OFF" when brake warning lamp is on because of parking brake operation or low brake fluid level.

*2: CAN status indicates the condition of the CAN communication judged by each signal input.

1. Normal: If no problems were found in the past, CAN status indicates "0". If the system is presently operating properly, but had a malfunction in the past, the CAN status will indicate "39-1".
2. Malfunction: If there is a malfunction, CAN indicates "40".

After the system returns to its normal operating condition, every time the ignition switch is cycled (turned OFF from ON), a value will be removed from the counter (i.e. "39" "-->38" "-->37"... "1"). If a malfunction is detected again, CAN status indicates "40". (Although the system has returned to normal operating condition, "0" is not immediately indicated. To reset, select and press "ERASE" on the "SELF-DIAGNOSIS" screen.)
