Passive Arming Mode

WARNING: This page is about a different car, the 2003 Lexus RX 300 and 2002 Lexus RX 300. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

This mode can be switched according to the specified operation.
All initially set modes (when shipped from factory) are active mode. (No passive mode).

For passive arming mode flowchart, see Fig 1. In arming condition either closed door is opened, entry delay occurs (15 seconds). See Fig 2. During this time, the mode transfers to the disarming condition when the condition described, is met. When the condition is not met, the system judges theft occurrence, the mode transfers to alarming condition.

Indicator Light Output

Refer to INSPECTING INDICATOR LIGHT OUTPUT (PASSIVE ARMING MODE) table. Even in the disarming condition, the indicator light flashes due to the signal output from the immobilizer system. The indicator always flashes receiving the signal from the immobilizer system at any time in the arming condition. The flashing frequency is 0.75 seconds when ON and 1.25 seconds when OFF.

INSPECTING INDICATOR LIGHT OUTPUT (PASSIVE ARMING MODE)

Condition	Indicator Light
Disarming Condition	OFF
Arming Preparation Condition	ON
Arming Condition (Entry Delay Time)	OFF (ON)
Alarming Condition	ON

Transfer To Active Mode

In each passive mode, when the disarming condition of the active mode switches to arming preparation transfer condition, the active mode transfers to each condition. In this case, active mode continues till disarming condition. See IDENTIFYING TRANSFER TO ACTIVE MODE table.

IDENTIFYING TRANSFER TO ACTIVE MODE

Passive Mode When Transfer Condition Is Met	Active Mode Transfer Condition
Disarming Condition	Arming Preparation Condition
Arming Preparation Condition	Arming Preparation Condition
Arming Condition (During Entry Delay Time)	Arming Condition (After Alarming Time Has Elapsed, Arming Condition)
Alarming Condition	After Alarming Time Has Elapsed, Arming Condition

Hook up the break-out-box and hand-held tester to the vehicle. See Fig 3.
Read the ECU input/output values by following the prompts on the tester screen.
Refer to the hand-held tester Snapshot function. This records the measured data and is effective in the diagnosis of intermittent problems.
