5. ECU (ELECTRONIC CONTROL UNIT)
Many ECUs are mounted in this vehicle.
Take the following precautions during body repair to prevent damage to the ECUs.

Before starting electric welding operations, disconnect the negative (-) terminal cable from the battery.
When the negative (-) terminal cable is disconnected from the battery, memory of the clock and audio
systems will be cancelled. So before starting work, make a record of the contents memorized by each
memory system. Then when work is finished, reset the clock and audio systems as before.
When the vehicle has tilt and telescopic steering, power seat and outside rear view mirror, which are all
equipped with memory function, it is not possible to make a record of the memory contents. So when the
operation is finished, it will be necessary to explain this fact to the customer, and request the customer to
adjust the features and reset the memory.

Do not expose the ECUs to ambient temperatures above 80°C (176°F).
NOTICE: If it is possible the ambient temperature may reach 80° (176°F) or more, remove the ECUs
from the vehicle before starting work.

Be careful not to drop the ECUs and not to apply physical shocks to them.

Fail Safe Function:
If either of the shift solenoid valve circuits develops an open or short, the ECM turns the other shift solenoid
ON and OFF to shift to the gear positions shown in the table below.
Manual shifting as shown in the following table must be done (In the case of a short circuit, the ECM stops
sending current to the short circuited solenoid).

(b) Inspect the DLC3.
The vehicle's ECM uses ISO 9141-2 for communication.
The terminal arrangement of DLC3 complies with SAE
J1962 and matches the ISO 9141-2 format.
Tester connectionConditionSpecified condition
7 (Bus
Line) - 5 (Signal ground)During communicationPulse generation
4 (Chassis Ground) - BodyAlways1 W or less
5 (Signal Ground) - BodyAlways1 W or less
16 (B+) - BodyAlways9 to 14 V
HINT:
If your display shows UNABLE TO CONNECT TO VEHICLE
when you have connected the cable of the OBD II scan tool or
hand-held tester to the DLC3, turned the ignition switch ON
and operated the scan tool, there is a problem on the vehicle
side or tool side.

If the communication is normal when the tool is connected
to another vehicle, inspect the DLC3 on the original ve-
hicle.

If the communication is still impossible when the tool is
connected to another vehicle, the problem is probably in
the tool itself, so consult the Service Department listed in
the tool's instruction manual.
(c) Inspect the battery voltage.
Battery Voltage: 11 to 14 V
If voltage is below 11 V, recharge the battery before proceeding.
(d) Check the MIL.
(1) The MIL comes on when the ignition switch is turned
ON and the engine is not running.
HINT:
If the MIL does not light up, troubleshoot the combination meter
(See page BE-63).
(2) When the engine is started, the MIL should go off.
If the lamp remains on, it means that the diagnosis
system has detected a malfunction or abnormality
in the system.

6. DEFINITION OF TERMS
TermDefinition
Monitor descriptionDescription of what the ECM monitors and how it detects malfunctions (monitoring purpose and its details).
Related DTCsDiagnostic code
Typical enabling condition
Preconditions that allow the ECM to detect malfunctions.
With all preconditions satisfied, the ECM sets the DTC when the monitored value(s) exceeds the malfunction
threshold(s).
Sequence of operation
The priority order that is applied to monitoring, if multiple sensors and components are used to detect the malfunc-
tion.
While another sensor is being monitored, the next sensor or component will not be monitored until the previous
monitoring has concluded.
Required sensor/compo-
nentsThe sensors and components that are used by the ECM to detect malfunctions.
Frequency of operation
The number of times that the ECM checks for malfunctions per driving cycle.
ºOnce per driving cycleº means that the ECM detects malfunction only one time during a single driving cycle.
ºContinuousº means that the ECM detects malfunction every time when enabling condition is met.
DurationThe minimum time that the ECM must sense a continuous deviation in the monitored value(s) before setting a
DTC. This timing begins after the ºtypical enabling conditionsº are met.
Malfunction thresholdsBeyond this value, the ECM will conclude that there is a malfunction and set a DTC.
MIL operation
MIL illumination timing after a defect is detected.
ºImmediatelyº means that the ECM illuminates MIL the instant the ECM determines that there is a malfunction.
º2 driving cycleº means that the ECM illuminates MIL if the same malfunction is detected again in the 2nd driving
cycle.

16. MANUAL SHIFTING TEST
HINT:
By this test, it can be determined whether the trouble is within
the electrical circuit or is a mechanical problem in the transmis-
sion.
(a) Disconnect the transmission wire.
(b) Inspect the manual driving operation.
Check that the shift and gear positions correspond with
the table below.
While driving, shift through the L, 2, 3, 4 and D positions.
Check that the gear change corresponds to the shift posi-
tion.
Shift PositionGear Position

44th
33rd
21st
L1st
RReverse
PPawl Lock
HINT:
If the gear positions of the L, 2, 3, 4 and D are difficult to distin-
guish, do the following road test.
If any abnormality is found in the above test, the problem is in
the transmission itself.
(c) Connect the transmission wire.
(d) Cancel out DTC.
