INSPECTION
PROCEDURE
1. INSPECT ELECTRICAL KEY TRANSMITTER SUB-ASSEMBLY
(a) Inspect the operation of the electrical key transmitter sub-assembly.
(1) Remove the transmitter battery from the electrical key transmitter sub-assembly
(See page ).
(2) Install a new or known good transmitter battery (See page
NOTICE: 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 sub-assembly from being damaged. HINT: If a new or known good transmitter battery is not available, first connect 2 new 1.5 V batteries in series. Then connect leads to the batteries and apply 3 V to the electrical key transmitter sub-assembly, as shown in the illustration. |

(3) 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.
(b) Inspect the transmitter battery capacity.
(1) Remove the transmitter battery (See page
) 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.
NOTICE:
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.
(2) Carefully pull the lead wire out from the position shown in the illustration and install the previously removed transmitter battery. NOTICE: 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 sub-assembly from being damaged. |

(3) Check the transmitter battery voltage. Text in Illustration
HINT: 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 (See page
Standard Voltage:
If the result is not as specified, replace the transmitter battery. |

Pressure Control Solenoid "C" Performance (Shift Solenoid Valve SL3) (P0796)
SYSTEM DESCRIPTION
The ECM uses the vehicle speed signal and signals from the transmission revolution
sensors (NT, SP2) to detect the actual gear (1st, 2nd, 3rd, 4th, 5th or 6th gear).
The ECM compares the actual gear with the shift schedule in the ECM memory to
detect mechanical problems of t ...
