SYSTEM DESCRIPTION ENTRY AND START DESCRIPTION 1. The entry and start uses a push-type ignition switch, which the driver can operate by merely carrying the key. This system consists primarily of the main body ECU, ignition switch, ID code box, steering lock ECU, key, ACC CUT relay, IG1 relay, IG2 relay and certification ECU. The main body ECU controls the system. This function operates in cooperation with the entry and start system. The table below shows the transition of the ignition switch, which depends on whether the clutch pedal is depressed or released. 2. This system has different power source mode patterns depending on the clutch pedal conditions. Clutch Pedal Not depressed For M/T: Power Source Mode Pattern Each time ignition switch is pushed off on (ACC) on (IG) off When ignition switch is pushed in the engine started condition Not depressed Engine started off When ignition switch is pushed once Depressed off engine start When ignition switch is pushed in the on (ACC) condition Depressed on (ACC) engine start Depressed When ignition switch is pushed in the on (IG) condition

When the engine switch is pushed once. OFF IG ON (after the engine is started) Not Depressed N Position Except N Position 8. Each time the engine switch is pushed. OFF ACC IG ON OFF 9. Each time the engine switch is pushed. OFF ACC IG ON OFF - N Position 10. When the engine switch is pushed in the IG- ON condition. IG ON (engine is started or not started) OFF - Except N Position 11. When the engine switch is pushed in the IG- ON condition. IG ON (engine is started or not started) OFF When the battery of the key is low, the entry and start function can be operated by holding the key against the ignition switch. FUNCTION OF COMPONENT

Components Ignition Switch (Transponder Key Amplifier) Key Indoor Electrical Key Oscillator (Front and Rear) Entry Door Control Receiver Main Body ECU Function Transmits ignition switch signal to main body ECU. Informs driver of power source mode or system abnormality with indicator light illumination. Receives ID code and transmits it to certification ECU when battery of key is low. Receives signals from oscillators and returns ID code to entry door control receiver. Receives request signal from certification ECU and forms detection area in vehicle interior. Receives ID code from key and transmits it to certification ECU. Changes power source mode in 4 stages (off, on (ACC), on (IG), start) in accordance with state of clutch start switch or park/neutral start switch. Controls entry and start function in accordance with signals received from switches and each ECU. Certification ECU Stop Light Switch Clutch Start Switch (M/T) ID Code Box ECM Certifies ID code received from entry door control receiver and transmits certification results to ID code box and steering lock ECU. Outputs state of brake pedal to main body ECU. Outputs state of clutch pedal to main body ECU. Receives steering unlock or engine immobiliser unset signals from certification ECU, certifies them, and transmits each unset signal to steering lock ECU or ECM. Receives engine start request signal from power source control ECU, turns ON ST relay, and starts engine. Receives signal from immobiliser code ECU and performs engine ignition and injection.

SYSTEM FUNCTION The electric controls of the entry and start function are described below: Control Ignition Switch Control Diagnosis Outline When driver operates ignition switch with key in driver's possession, certification ECU starts indoor electrical key oscillator, which transmits request signal to key. Upon receiving this signal, key transmits ID code signal to main body ECU. ID code box verifies check results received from certification ECU via LIN and sends them to main body ECU. Based on these results, main body ECU authorizes operation of ignition switch. When main body ECU detects malfunction, main body ECU diagnoses and memorizes failed section. CONSTRUCTION AND OPERATION 1. Ignition Switch Ignition switch consists of a momentary type switch, 3 color (amber, green, greenish white) LEDs, and transponder key amplifier. The greenish white LED is for illumination. The amber and green LEDs are for the indicator lights. The driver can check the present power source mode and whether the engine can start or not in accordance with the illumination state of the indicator light. When the main body ECU detects an abnormality in the entry and start system, it makes the amber indicator light flash. If the engine stopped in this state, it might not be possible to restart it. 2. Indicator Light Condition

Power Source Mode/Condition Ignition switch indicator light condition Clutch pedal released (M/T) Brake pedal released (except M/T) Indicator Light Condition Clutch pedal depressed (M/T) Brake pedal depressed (except M/T) Off OFF Illuminates (Green) On (ACC, IG) Illuminates (Amber) Illuminates (Green) Engine running OFF OFF Steering lock not unlocked System malfunction Clutch switch malfunction (M/T) Flashes (Green) for 15 seconds Flashes (Amber) for 15 seconds Flashes (Green) for 15 seconds Flashes (Green) for 15 seconds Flashes (Amber) for 15 seconds Flashes (Green) for 15 seconds 3. Main Body ECU The main body ECU consists of the IG1 and IG2 relay actuation circuits and CPU. WHEN KEY BATTERY IS LOW

1. To operate the entry and start function when the key battery is low, hold the TOYOTA mark of the key against the ignition switch while depressing the brake pedal. 2. The main body ECU transmits a key verification request signal from the stop light switch to the certification ECU. 3. The certification ECU does not receive an ID code response from the smart tuner, so it actuates the transponder key amplifier built into the ignition switch. 4. The transponder key amplifier outputs an engine immobiliser radio wave to the key. 5. The key receives the radio wave, and returns a radio wave response to the transponder key amplifier. 6. The transponder key amplifier combines the key ID codes with the radio wave response, and transmits it to the certification ECU. 7. The certification ECU judges and verifies the ID code, and transmits a key verification OK signal to the main body ECU. The buzzer in the combination meter sounds at the same time. 8. After the buzzer sounds, if the ignition switch is pressed within 5 seconds with the brake pedal not depressed, the power source mode changes to on (ACC) or on (IG), the same as in the normal condition.

DIAGNOSIS The main body ECU can detect malfunctions in the entry and start function when the power source mode is on (IG). When the ECU detects a malfunction, the amber indicator light of the ignition switch flashes to warn the driver. At the same time, the ECU stores the 5-digit DTC (Diagnostic Trouble Code) in the memory. The indicator light warning continues for 15 seconds even after the power source mode is changed to off. The DTC can be read by connecting the intelligent tester to the DLC3. The entry and start function cannot be operated if a malfunction occurs.

HINT: Connect the cable of the intelligent tester to the DLC3, turn the ignition switch on (IG) and attempt to use the tester. If the display indicates that a communication error has occurred, there is a problem either with the vehicle or with the tester. If communication is normal when the tester is connected to another vehicle, inspect the DLC3 of the original vehicle. If communication is still not possible when the tester is connected to another vehicle, the problem is probably in the tester itself. Consult the Service Department listed in the tester's instruction manual. INSPECT BATTERY VOLTAGE If the voltage is below 11 V, recharge or replace the battery before proceeding.
