PROCEDURE
INSPECT ELECTRICAL KEY TRANSMITTER SUB-ASSEMBLY
Inspect the operation of the electrical key transmitter sub-assembly. (Type A)
Remove the transmitter battery from the electrical key transmitter sub-assembly.
Install a new or known good transmitter battery.
Note
When replacing the transmitter battery, before starting work, remove static electricity that has built up in the body by touching, for example, the vehicle to prevent the electrical key transmitter from being damaged.
Tech Tips
If a new or known good transmitter battery is not available, connect 2 new 1.5 V batteries in series and connect leads from the batteries to the electrical key transmitter sub-assembly as shown in the illustration.
From outside the vehicle, approximately 1 m (3.28 ft.) away from the driver door outside door handle, test the electrical key transmitter sub-assembly by pointing its key plate at the vehicle and pressing an electrical key transmitter sub-assembly switch.
OK |
---|
The door lock can be operated via the electrical key transmitter sub-assembly. |
The LED comes on more than once. |
The operation area differs depending on the user, the way the electrical key transmitter sub-assembly is held, and the location.
The electrical key transmitter sub-assembly weak radio waves may be affected if the area has strong radio waves or noise. The electrical key transmitter sub-assembly operation area may be shortened or the electrical key transmitter sub-assembly may not function.
Inspect the transmitter battery capacity. (Type A)
Remove the transmitter battery from the electrical key transmitter sub-assembly that does not operate. Attach a lead wire (0.6 mm (0.0236 in.) in diameter or less including wire sheath) with tape or equivalent to the negative terminal.
Note
Do not wrap the lead wire around a terminal, wedge it between the terminals, or solder it. A terminal may be deformed or damaged, and the transmitter battery will not be able to be installed correctly.
Carefully pull the lead wire out from the position shown in the illustration and install the previously removed transmitter battery.
Note
When replacing the transmitter battery, before starting work, remove static electricity that has built up in the body by touching, for example, the vehicle to prevent the electrical key transmitter from being damaged.
*a | GND |
Check the transmitter battery voltage.
Tech Tips
When measuring the transmitter battery voltage, while operating the lock sensor of a door handle, bring the electrical key transmitter sub-assembly within the entry operating range to perform the measurement. For the entry operating range, refer to System Description.
Tester Connection | Condition | Specified Condition |
---|---|---|
Transmitter battery positive (+) - Transmitter battery negative (-) | Engine switch off, all doors closed and lock sensor touched | 2.3 to 3.2 V |
If the result is not as specified, replace the transmitter battery.
Inspect the operation of the electrical key transmitter sub-assembly. (Type B)
Remove the transmitter battery from the electrical key transmitter sub-assembly.
Install a new or known good transmitter battery.

INSTALL ELECTRICAL KEY TRANSMITTER SUB-ASSEMBLY (for Card Type)
Inspect the operation of the electrical key transmitter sub-assembly (for Card Type).
Remove the transmitter battery from the electrical key transmitter sub-assembly (for Card Type).
Install a new or known good transmitter battery.
Tech Tips
If a new or known good transmitter battery is not available, connect 2 new 1.5 V batteries in series and connect leads from the batteries to the electrical key transmitter sub-assembly (for Card Type) as shown in the illustration.
Hold the electrical key transmitter sub-assembly (for Card Type) facing towards the vehicle approximately 1 m (3.28 ft.) away from the driver door outside handle assembly and check that the doors lock when the lock switch on the driver door outside handle assembly is pressed.
OK |
---|
All doors can be locked. |
Note
Make sure the engine switch is off.
Make sure to close all doors.
Do not wedge the tip of the tester lead between the terminals, as a terminal may be deformed or damaged.
Inspect the transmitter battery capacity.
Remove the transmitter battery from the electrical key transmitter sub-assembly (for Card Type) that does not operate. Attach a lead wire to the negative (-) and positive (+) sides of the transmitter battery with tape or equivalent.
Note
Do not wrap the lead wire around a terminal, wedge it between the terminals, or solder it. A terminal may be deformed or damaged, and the transmitter battery will not be able to be installed correctly.
*a | GND |
Check the transmitter battery voltage.
Tech Tips
When measuring the transmitter battery voltage, while operating the lock switch of a door handle, bring the electrical key transmitter sub-assembly (for Card Type) within the entry operation range to perform the measurement. For the entry operation range, refer to Operation Check.
Tester Connection | Condition | Specified Condition |
---|---|---|
