diagrams and index.
(2) In each section, all specifications are listed, including optional specifications. Accordingly, some
specifications may not be applicable for individual vehicles.
SectionBasic contents
Wiring harness

diagramsConnector locations and harness wiring configurations on actual vehicles are illustrated.
Single part
installation positionLocations are shown for each point of relays, electronic control units, sensors, solenoids,
solenoid valves, diodes, inspection connectors, spare connectors, fusible links, fuses, etc. In the
part’s lists, parts are listed in alphabetical order.
Circuit diagramsCircuits from power supply to earth are shown completely, classified according to system. There
is a main division into power circuits, and circuits classified by system. The circuits classified by
system also include operation and troubleshooting hints.
DJunction block
The entire circuit for the junction block is described, because only the part of the junction
block needed is normally shown in each circuit diagram.
DJoint connectors
The internal circuits for all joint connectors are described, because only the part needed
is shown in each circuit diagram.
DPower supply circuits
Circuits from the battery to fusible link, dedicated fuses, ignition switch, general purpose
fuses, etc.
DCircuits classified by system
For each system, the circuits are shown from fuse to earth, excluding the power supply
sections.
DOperation
The standard operation of each system is briefly described, following the route of current
flow.
DTroubleshooting hints
This is a brief explanation of the inspection points that serve as hints when troubleshooting.
Explanations of the circuits controlled by the electronic control unit are omitted. Refer
to the related publications as required.
IndexAll components used are listed by connector number and component name.

GENERAL -How to Use Troubleshooting/Inspection Service Points00-10
HOW TO USE THE INSPECTION PROCEDURES
The causes of a high frequency of problems occurring in electronic circuitry are generally the connectors,
components, the ECU and the harnesses between connectors, in that order. These inspection procedures
follow this order, and they first try to discover a problem with a connector or a defective component.

mode switch is pressed.

Check trouble symptom.
Replace the ECS-ECU.
In the above cases, the ECS switch circuit is defective or the indicator
circuit is defective.

2. Indicates inspection carried out using the
MUT-II.
Indicates the operation and inspection proce-
dures.
Indicates the OK judgement conditions.
3. Detailed inspection procedures (methods)
such as component inspection and circuit
inspection are listed on a separate page, and
are given here for reference.
5. Inspect the contact condition at each connector terminal.
(Refer to Connector Inspection Service Points.)
The connector position can be located in the wiring diagram in the
electrical wiring manual by means of this symbol.
Caution
After carrying out connector inspection, always be sure to
reconnect the connector as it was before.
6. Confirm that there are trouble symptoms. If trouble symptoms have
disappeared, the connector may have been inserted incorrectly and the
trouble symptom may have disappeared during inspection.
If it seems that trouble symptoms still remain, proceed to the next page of
instructions.
7. If trouble symptoms still remain up to this stage, there is a possibility that there is an
open or short circuit in the harness between the connectors, so check the harness.
Alternatively, the cause may be a defective ECU, so try replacing the ECU and check
if the trouble symptom disappears.

4. Indicates voltage and resistance to be measured at a particular
connector.
(Refer to Connector Measurement Service Points.)
The connector position can be located in the wiring diagram in the
electrical wiring manual by means of this symbol.
Indicates operation and inspection procedures, inspection terminals
and inspection conditions.
Indicates the OK judgement conditions.
HARNESS INSPECTION
Check for an open or short circuit in the harness between the terminals which were defective according
to the connector measurements. Carry out this inspection while referring to the electrical wiring manual.
Here, “Check harness between power supply and terminal xx” also includes checking for blown fuses.
For inspection service points when there is a blown fuse, refer to “Inspection Service Points for a Blown
Fuse.”
MEASURES TO TAKE AFTER REPLACING THE ECU
If the trouble symptoms have not disappeared even after replacing the ECU, repeat the inspection procedure
from the beginning.

TROUBLESHOOTING
BEFORE COMMENCING TROUBLESHOOTING
Before starting troubleshooting, check the following two points to ensure there are no defects.
DCheck the state of the connector couplings to the ETACS-ECU and junction box.
DCheck that the fuses and fusible links relating to all systems are not fused.
STANDARD FLOW OF DIAGNOSTIC TROUBLESHOOTING
Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points.
DIAGNOSTIC FUNCTIONS
READING DIAGNOSIS CODES
Read the diagnosis codes using MUT-II. (Refer to GROUP 00 - How to Use Troubleshooting/Inspection
Service Points.)
NOTE
1. Connect MUT-II to the 16-pin diagnosis connector (black).
2. The diagnosis code cannot be read when there is an ETACS-ECU fault or when the power is first
turned ON (voltage rising). In this case, refer to “No Communication with MUT-II” (P. 54B-10) on
Fault Symptom Inspection Procedure, and perform troubleshooting.
