INTELLIGENT KEY SYSTEM
The headlamp flashes and the horn sounds intermittently.
The alarm automatically turns off:
• After 25 seconds
• When Intelligent Key unit receives any signal from remote controller of Intelligent Key
• When door request switch is pressed (Intelligent Key is outside vehicle)
Panic alarm function's press and holding time value can be changed in “PANIC ALARM DELAY” mode in
“WORK SUPPORT”. Refer to BL-117, "
CONSULT-III Application Item".
List of Operation Related Parts
Parts marked with × are the parts related to operation.
ENGINE START FUNCTION
When the registered Intelligent Key is carried, the engine can be started without inserting the key.
When ignition knob switch is ON (press ignition switch ), Intelligent Key unit searches Intelligent Key in the
vehicle using inside key antenna.
Then Intelligent Key is inside the vehicle, it performs the following operation.
• Illuminate green “KEY” warning lamp in combination meter.
• Released steering lock and ignition switch can be turned from OFF to ACC, ON or START position.
NOTE:
If Intelligent Key is not registered, “KEY” warning lamp in combination meter illuminates red.
• Intelligent Key sends engine start signal to BCM via CAN communication line.
When ignition switch turns to START position, BCM sends starter request signal to IPDM E/R. Then, engine
starts.

BRAKE BOOSTER
On Board InspectionINFOID:0000000005928405
OPERATING CHECK
• With the engine stopped, change the vacuum to the atmospheric pressure by depressing brake pedal sev-
eral times at intervals of 5 seconds.
• Then with brake pedal fully depressed, start engine and when the vacuum pressure reaches the standard, make sure that the clear-
ance between brake pedal and floor panel decreases.
AIRTIGHT CHECK
• Run engine at idle for approximately 1 minute, and stop it afterapplying vacuum to booster. Depress brake pedal normally to
change the vacuum to the atmospheric pressure. Make sure that
distance between brake pedal and floor panel gradually increases.
• Depress the brake pedal while engine is running, then stop engine with brake pedal depressed. The pedal
stroke should not change after holding pedal down for 30 seconds.

TROUBLE DIAGNOSIS
TROUBLE DIAGNOSIS
DTC Inspection Priority ChartINFOID:0000000005928748
If some DTCs are displayed at the same time, perform inspections one by one based on the following priority
chart.
NOTE:
If DTC “U1000” is displayed with other DTCs, first perform the trouble diagnosis for DTC “U1000”.
Refer to
CVT-56
.
Fail-SafeINFOID:0000000005928749
The TCM has an electrical fail-safe mode. This mode make s it possible to operate even if there is an error in a
main electronic control input/output signal circuit.
FAIL-SAFE FUNCTION
If any malfunction occurs in a sensor or solenoid, this function controls the CVT to make driving possible.
Secondary Speed Sensor
The shift pattern is changed in accordance with thrott le position when an unexpected signal is sent from the
secondary speed sensor to the TCM. T he overdrive-off mode is inhibited, and the transaxle is put in “D”.
Primary Speed Sensor
The shift pattern is changed in accordance with thro ttle position and secondary speed (vehicle speed) when
an unexpected signal is sent from the primary speed sensor to the TCM. The overdrive-off mode is inhibited,
and the transaxle is put in “D”.
Transmission Range Switch
If an unexpected signal is sent from the transmission range switch to the TCM, the transaxle is put in “D”.
CVT Fluid Temperature Sensor
If an unexpected signal is sent from the CVT fluid temperature sensor to the TCM, the gear ratio in use before
receiving the unexpected signal is maintained or t he gear ratio is controlled to keep engine speed under 3500
rpm.
Secondary Pressure Sensor
• If an unexpected signal is sent from the secondary pressure sensor to the TCM, the secondary pressure
feedback control is stopped and the offset value obtai ned before the non-standard condition occurs is used
to control line pressure.
• If secondary pressure sensor error signal is input to TCM, secondary pressure feedback control stops, but line pressure is controlled normally.
Line Pressure Solenoid
If an unexpected signal is sent from the solenoid to the TCM, the line pressure solenoid is turned OFF to
achieve the maximum fluid pressure.
Secondary Pressure Solenoid
If an unexpected signal is sent from the solenoid to t he TCM, the secondary pressure solenoid is turned OFF
to achieve the maximum fluid pressure.
Torque Converter Clutch Solenoid
If an unexpected signal is sent from the solenoid to t he TCM, the torque converter clutch solenoid is turned
OFF to cancel the lock-up.
Step Motor
If an unexpected signal is sent from the step motor to the TCM, the step motor coil phases “A” through “D” are
all turned OFF to hold the gear ratio used right before the non-standard condition occurred.
CVT Lock-up Select Solenoid
If an unexpected signal is sent from the solenoid to the TCM, the CVT lock-up select solenoid is turned OFF to
cancel the lock-up.
