DIAGNOSTICS - POWER SLIDE DOOR SYSTEM 05BZL-02
POWER SLIDE DOOR RH DOES NOT OPERATE WHEN SWITCH* IS
PRESSED
* "SWITCH" indicates the satellite switch for the power slide door RH and the power slide door control switch
RH
CIRCUIT DESCRIPTION
S The power slide door operates only when the power slide door main switch is ON (switch free: orange
paint on the top of the switch appears). The power slide door ECU RH controls the power slide door
RH, which activates the slide door motor to open/close the slide door.
S A request signal from the satellite switch for the power slide door RH is input to the the driver side junc-
tion block ECU, which then sends this request signal using a BEAN line to the power slide door ECU
RH.
S A request signal from the power slide door control switch RH is directly input to the power slide door
ECU RH.
S When the child lock is in the locked condition, the power slide door control switch RH is disabled, thus
the power slide door RH is not activated by this switch.
S When the touch sensor has an open/short-circuit, closing of the power slide door is disabled.
NOTICE:
When disconnecting the negative (-) terminal cable of the battery or control motor and clutch, initial-
ize the power slide door system (See page 05-1650 ).

DIAGNOSTICS - POWER SLIDE DOOR SYSTEM
INSPECTION PROCEDURE
1 BASIC INSPECTION
(a) Conditions necessary for the power slide door to open:
(1) Power slide door main switch is in the ON position (switch free: orange paint on the top of the
switch appears).
(2) Slide door is unlocked (door lock position switch is in the ON position when the slide door is fully
closed).
(3) Shift lever is in the P position when the ignition switch is ON (When the ignition switch is OFF,
the power slide door operates at any position of the shift lever.)
(b) Conditions necessary for the power slide door to close:
(1) Power slide door main switch is in the ON position (switch free: orange paint on the top of the
switch appears).
(2) Slide door is between approximately the half-open position and the fully open position.
(3) Slide door touch sensor is not damaged and deformed.
