q19Current flow arrowI
Arrow indicates electric current flow, especially where the direction of standard
flow (vertically downward or horizontally from left to right) is difficult to follow.
I A double arrow ªF Ð
Eº shows that current can flow in either direction depending on
circuit operation.
q20System branch I
This shows that the system branches to another system identified by cell code
(section and system).
q21Page crossing I
This arrow shows that the circuit continues to another page identified by cell code.
I The C will match with the C on another page within the system other than the next
or preceding pages.
q22Shielded line IThe line enclosed by broken line circle shows shield wire.
q23Component box in wave
line I
This shows that another part of the component is also shown on another page
(indicated by wave line) within the system.
q24Component name IThis shows the name of a component.
q25Connector number I
This shows the connector number.
I The letter shows which harness the connector is located in.
Example: M: main harness. For detail and to locate the connector, refer to EL sec-
tion (ªMain Harnessº, ªHARNESS LAYOUTº). A coordinate grid is included for com-
plex harnesses to aid in locating connectors.
q26Ground (GND) I
The line spliced and grounded under wire color shows that ground line is spliced
at the grounded connector.
q27Ground (GND) IThis shows the ground connection.
q28Connector views I
This area shows the connector faces of the components in the wiring diagram on
the page.
q29Common component I
Connectors enclosed in broken line show that these connectors belong to the
same component.
q30Connector color I
This shows a code for the color of the connector. For code meaning, refer to wire
color codes, Number q14of this chart.
q31Fusible link and fuse box I
This shows the arrangement of fusible link(s) and fuse(s), used for connector
views of ªPOWER SUPPLY ROUTINGº in EL section.
The open square shows current flow in, and the shaded square shows current
flow out.
q32Reference area I
This shows that more information on the Super Multiple Junction (SMJ) and Joint
Connectors (J/C) exists on the foldout page. Refer to GI-18 for details.

Trouble Diagnoses
If doors can not be unlocked by remote controller operation then the following procedure is required.
A) Unlock the vehicle by a mechanical key in the drivers door key cylinder.Note: this may cause the alarm to sound.
B) Put the key in ignition, turn to ON position for at least five seconds. Assuming the ignition key contains a valid transponder then a signal will be generated by the immobilizer which will disarm the alarm and allow
key learn mode to be entered.
C) Turn ignition OFF and wait for ten seconds.
