Time Lag Test
1. Perform mechanical system test preparation. (See K2–72 Mechanical System Test Preparation.)
2. Start the engine.
3. Warm up the engine until the ATF temperature reaches 60—70°C {140—158°F}. Shift the selector lever from N
position to D range.
4. Use a stopwatch to measure the time it takes from shifting until engagement is felt. Take three measurements
for each test and average the results using the following formula.
Formula
Average time lag = (Time 1 + Time 2 + Time 3) / 3
5. Perform the test for the following shifts in the same manner.
•N position → P position
Time lag
N → D range ... approx. 0.5—1.0 second
N → R position ... approx. 0.6— 1.0 second
Evaluation of time lag test
End Of SieROAD TESTA6E571401030210Road Test Preparation
1. Inspect the engine coolant. (See Section E.)
2. Inspect the engine oil. (See D–8 ENGINE OIL INSPECTION.)
3. Inspect the ATF levels. (See K2–78 AUTOMATIC TRANSAXLE FLUID (ATF) INSPECTION.)
4. Inspect the idle speed and ignition timing in P position. (See F1–22 IDLE SPEED INSPECTION (4WD).)
5. Bring up the engine and transaxle to normal operating temperature.

End Of SieCOMBINE SENSOR (FORWARD-G SENSOR)A6E692067650202Function
•The forward-G sensor is integrated with the combine sensor to detect and calculate the vehicle forward-G force
and change in voltage to the DSC HU/CM.
Structure/Operation
•The drive train of 4WD vehicles delivers driving force to all four wheels, and due to this interlocking, the speed
of all wheels during braking is the same. When driving on road surfaces with especially low m (friction
coefficient), it is difficult to estimate the vehicle speed based on the wheel speed, and DSC braking becomes
unreliable. (For 2WD vehicles, the front and rear wheels are independent, so it is possible to accurately
estimate the vehicle speed by measuring the difference between the rotation speeds of the front and rear tires.)
A forward-G sensor has been installed to overcome this situation. When braking, the change in G-force is
detected, and the road surface m is judged (low m, high m), enabling a correction of the vehicle speed
estimation.
•The output voltage characteristic for the combine sensor is 2.5 V when the vehicle is standing still, and
changes accordingly as forward-G is formed.
•Forward-G is formed when the sensor detects an inertial force created by, and in proportion to, a G- force
acting on a silicon detection component.

CONTROLLER AREA NETWORK (CAN)A6E692067650203•ABS (ABS/TCS) or DSC HU/CM transmit/receive information through CAN. Due to the addition of TCM, 4WD
CM, and the MZR-CD (RF Turbo) engine model, the following information has been changed. For detailed
information on CAN, see the “CONTROLLER AREA NETWORK.” (See T–3 OUTLINE.)
Transmitted Information
•Coupling torque request (to 4WD CM)
•DSC operating condition (to 4WD CM)
Received Information
•Coupling torque (from 4WD CM)
•Shift position (from TCM)

CURTAIN AIR BAG MODULE REMOVAL/INSTALLATIONA6E813000171201
Warning
•Handling the air bag module improperly can accidentally deploy the air bag module, which may
seriously injure you. Read AIR BAG SYSTEM SERVICE WARNINGS before handling the air bag
module. (See T–32 SERVICE WARNINGS.)
1. Turn the ignition switch to LOCK position.
2. Disconnect the negative battery cable and wait for more than 1 minute.
3. Remove the headliner.
4. Remove in the order indicated in the table.
5. Install in the reverse order of removal.
6. Turn the ignition switch to ON position.
7. Verify that the air bag system warning light
illuminates for approximately 6 seconds and
then goes off.
•If the air bag system warning light does not
operate in the manner described above, there
are malfunctions in the system. Inspect the system using the on-board diagnostic.
Connector Removal Note
1. Using a flathead screwdriver, pry out the
connector's stopper plate.
2. Disconnect the connector.
End Of SieAIR BAG MODULE AND PRE-TENSIONER SEAT BELT DEPLOYMENT PROCEDURESA6E813057000201
Warning
•A live (undeployed) air bag module and pre-tensioner seat belt may accidentally deploy when it is
disposed of and cause serious injury. Do not dispose of a live (undeployed) air bag module and
pre-tensioner seat belt. If the SSTs (Deployment tool and Adapter harness) are not available,
consult the nearest Mazda representative for assistance.
Caution
•Deploying the air bag modules and pre-tensioner seat belts inside the vehicle may cause damage
to the vehicle interior. When the vehicle is not to be scrapped, always deploy the air bag modules
and pre-tensioner seat belts outside the vehicle.
•When the vehicle is to be scrapped, deploy the air bag modules and pre-tensioner seat belts inside the vehicle.
(See T–36 Deployment Procedure for Inside of Vehicle (Only When Vehicle Is To Be Scrapped).)
•When the vehicle is not to be scrapped, deploy the air bag modules and pre-tensioner seat belts outside the
vehicle. (See T–36 Deployment Procedure for Outside of Vehicle.)
Note
•When disposing of deployed air bag module and pre-tensioner seat belt, refer to the disposal procedure.
•The deployment procedures are the same as those of the current 4SD and 5HB models, except for the
curtain air bag module.
