during testing. An example would be if a problem appears only when the vehicle is cold but has not appeared when
warm. In this case, the technician should thoroughly make out a "CUSTOMER PROBLEM ANALYSIS SHEET" and
recreate (simulate) the environment and condition which occurred when the vehicle was having the issue.1. Clear Diagnostic Trouble Code (DTC).
2. Inspect connector connection, and check terminal for poor connections, loose wires, bent, broken or corroded pins,
and then verify that the connectors are always securely fastened.
3.Slightly shake the connector and wiring harness vertically and horizontally.
4. Repair or replace the component that has a problem.
5. Verify that the problem has disappeared with the road test.
● SIMULATING VIBRATION
a. Sensors and Actuators
: Slightly vibrate sensors, actuators or relays with finger.
Strong vibration may break sensors, actuators or relays
b. Connectors and Harness
: Lightly shake the connector and wiring harness vertically and then horizontally.
● SIMULATING HEAT
a. Heat components suspected of causing the malfunction with a hair dryer or other heat source.
a.DO NOT heat components to the point where they may be damaged.
b. DO NOT heat the ECM directly.
● SIMULATING WATER SPRINKLING
a. Sprinkle water onto vehicle to simulate a rainy day or a high humidity condition.
DO NOT sprinkle water directly into the engine compartment or electronic components.
● SIMULATING ELECTRICAL LOAD
a. Turn on all electrical systems to simulate excessive electrical loads (Radios, fans, lights, rear window defogger,
etc.).
CONNECTOR INSPECTION PROCEDURE

1.Handling of Connector
a. Never pull on the wiring harness when disconnecting connectors.
b.When removing the connector with a lock, press or pull locking lever.
c.Listen for a click when locking connectors. This sound indicates that they are securely locked.
d.When a tester is used to check for continuity, or to measure voltage, always insert tester probe from wire
harness side.

e.Check waterproof connector terminals from the connector side. Waterproof connectors cannot be accessed from
harness side.
a.Use a fine wire to prevent damage to the terminal.
b. Do not damage the terminal when inserting the tester lead.
2. Checking Point for Connector
a. While the connector is connected:
Hold the connector, check connecting condition and locking efficiency.
b. When the connector is disconnected:
Check missed terminal, crimped terminal or broken core wire by slightly pulling the wire harness.
Visually check for rust, contamination, deformation and bend.
c. Check terminal tightening condition:
Insert a spare male terminal into a female terminal, and then check terminal tightening conditions.
d. Pull lightly on individual wires to ensure that each wire is secured in the terminal.
3.Repair Method of Connector Terminal
a. Clean the contact points using air gun and/or shop rag.

Never use sand paper when polishing the contact points, otherwise the contact point may be damaged.
b. In case of abnormal contact pressure, replace the female terminal.
WIRE HARNESS INSPECTION PROCEDURE
1.Before removing the wire harness, check the wire harness position and crimping in order to restore it correctly.
2. Check whether the wire harness is twisted, pulled or loosened.
3. Check whether the temperature of the wire harness is abnormally high.
4. Check whether the wire harness is rotating, moving or vibrating against the sharp edge of a part.
5. Check the connection between the wire harness and any installed part.
6. If the covering of wire harness is damaged; secure, repair or replace the harness.
ELECTRICAL CIRCUIT INSPECTION PROCEDURE
● CHECK OPEN CIRCUIT
1. Procedures for Open Circuit
a. Continuity Check
b. Voltage Check
If an open circuit occurs (as seen in [FIG. 1]), it can be found by performing Step 2 (Continuity Check Method) or
Step 3 (Voltage Check Method) as shown below.
2. Continuity Check Method
When measuring for resistance, lightly shake the wire harness above and below or from side to side.
Specification (Resistance)
1Ω or less → Normal Circuit
1MΩ or Higher → Open Circuit
a. Disconnect connectors (A), (C) and measure resistance between connector (A) and (C) as shown in [FIG. 2].
In [FIG.2.] the measured resistance of line 1 and 2 is higher than 1MΩ and below 1 Ω respectively. Specifically
the open circuit is line 1 (Line 2 is normal). To find exact break point, check sub line of line 1 as described in
next step.

BRAKES
The gear changing mechanism utilizes two multi- disc brakes.
LOW&REVERSE BRAKE AND SECOND BRAKE
The low&reverse brake(A) operates in 1st and reverse gears, when the vehicle is parked, and during manual
operation. It locks the low&reverse annulus gear and overdrive planetary carrier to the case.
The second(C) brake(B) operates in 2nd and 4th gears and locks the reverse sun gear(D) to the case.
The components comprising the low&reverse brake and second brake are as illustrated below.
As shown, the discs and plates of the two brakes are arranged on either side of the rear cushion plate(E), which is
itself secured to the case(F) by a snap ring.
OWC
To improve the shift feeling from 1st to 2nd gear, OWC was adopted on the low&reverse brake annulus gear. Instead
of hydraulic fixing by Low&reverse brake at the 1st gear, this mechanical fixing device was used. This structure is not
a new concept, because this OWC already has been installed on the previous models.
ACCUMULATORS
NumberFunction Name Color
1 Low&Reverse Brake None
2 Underdrive Clutch Yellow
3 Second Brake Blue
4 Overdrive Clutch None

Objective
* Energy (hydraulic pressure) storage
* Impact and pulsation damping when solenoid valves operating
* Operation as spring element
* Smooth shifting by preventing sudden operation of clutches and brakes
TRANSFER DRIVE GEAR
With the transfer drive gear, increased tooth height and a higher contact ratio have reduced gear noise.
Also, the bearing that supports the drive gear is a preloaded type that eliminates rattle, and the rigidity of the gear
mounting has been increased by bolting the bearing directly onto the case.
OUTPUT SHAFT/TRANSFER DRIVEN GEAR
As shown in the illustration below, the transfer driven gear is press- fitted onto the output shaft, and the output shaft is
secured by a locking nut and supported by bearings.
The locking nut has a left- handed thread, and a hexagonal hole in the other end of the shaft enables the shaft to be
held in position for locking nut removal.
