Resistance Inspection (On-Vehicle Inspection)
Caution
1. Disconnect the negative battery cable.
2. Remove the air cleaner component. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION.)
3. Disconnect the transaxle connector.
Note
4. Measure the resistance between the following terminals.
ATF temperature: -40-150 °C {-40-302 ° F}
5. Connect the transaxle connector.
6. Install the air cleaner component. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION.)
7. Connect the negative battery cable.
Operating Inspection
1. Disconnect the transaxle connector.
Caution
Note
2. Apply battery positive voltage to terminals A,B,C, F or G and battery negative voltage to GND, and verify that operating sound is heard from solenoid.
- If the transaxle harness is okay, perform the resistance inspection (off-vehicle inspection).
- If there is a problem, repair or replace the transaxle harness.
3. Apply battery positive voltage to terminal D and battery negative voltage to terminal I, and verify that operating sound is heard from solenoid.
- If transaxle harness is okay, perform the resistance inspection (off-vehicle inspection)
- If there is a problem, repair or replace the transaxle harness.
Resistance Inspection (Off-Vehicle Inspection)
1. Remove the control valve body. (See SOLENOID VALVE REMOVAL/INSTALLATION.)
2. Measure the resistance of each solenoid valve individually.
3. Install the control valve body. (See SOLENOID VALVE REMOVAL/INSTALLATION.)

Mazda 6 Service Manual: Key Battery Replacement
If the buttons on the transmitter are inoperable and the operation indicator
light does not flash, the battery may be dead.
Replace with a new battery before the transmitter becomes unusable.
CAUTION
Make sure the battery is installed correctly. Battery leakage could occur
