DESCRIPTION
except Manual Transaxle
-
When the electrical key transmitter sub-assembly is in the cabin and the engine switch is pressed, the certification ECU (smart key ECU assembly) receives a signal and changes the power source mode. Additionally, when the shift position is in P and the brake pedal is depressed, the engine can be started by pressing the engine switch. If the steering is unlocked, the engine can also be started by pressing the engine switch with the shift position in N and the brake pedal depressed.

WIRING DIAGRAM
CAUTION / NOTICE / HINT
HINT:
-
If the ignition switch is changed from ON to ACC with the shift position in any position other than P, and then the shift position is moved to P and the engine switch is pressed with the brake pedal depressed, the ignition switch will turn off.*
-
If the brake pedal is repeatedly depressed while the engine is stopped, the brake booster pressure will be released and the force required to depress the brake pedal to illuminate the stop lights will increase.*
-
*: except Manual Transaxle
PROCEDURE
1.
|
CHECK WHETHER ENGINE STARTS
|
(a) Using an electrical key transmitter sub-assembly which is registered to the vehicle, turn the ignition switch to ON.
(b) Check that the engine can be started 5 seconds after the ignition switch turned to ON.
OK:
Engine starts normally.

CHECK SECURITY INDICATOR LIGHT (IMMOBILISER FUNCTION UNSET)
|
(a) Get into the vehicle while carrying an electrical key transmitter sub-assembly.
(b) Move the shift position to P.*1
(c) Press the engine switch with the brake pedal released and check that the security indicator light changes from blinking to off at the same time that the power source mode changes to ACC.*1
(d) Press the engine switch with the clutch pedal released and check that the security indicator light changes from blinking to off at the same time that the power source mode changes to ACC.*2
OK:
The security indicator light changes from blinking to off at the same time that the power source mode changes to ACC.
HINT:
The immobiliser function can be determined to be operating correctly if the security indicator light changes from blinking to off at the same time that the power source mode changes to ACC.
