Revision: June 20062007 Versa
Precautions for On Board Diagnostic (OBD) System of A/T and EngineUCS005M 2
The ECM has an on board diagnostic system. It will light up the malfunction indicator lamp (MIL) to warn the
driver of a malfunction causing emission deterioration.
CAUTION:
Be sure to turn the ignition switch OFF and disconnect battery negative cable from battery nega-
tive terminal before any repair or inspection work. The open/short circuit of related switches, sen-
sors, solenoid valves, etc. will cause the MIL to light up.
Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MIL to light up due to an open circuit. (Be sure the connectors are free from water,
grease, dirt, bent terminals, etc.)
Be sure to route and secure the harnesses properly after work. Interference of the harness with a
bracket, etc. may cause the MIL to light up due to a short circuit.
Be sure to erase the unnecessary malfunction information (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.
PrecautionsUCS005M 3
Before connecting or disconnecting the TCM harness con-
nector, turn ignition switch OFF and disconnect the battery
cable from the negative terminal. Failure to do so may dam-
age the TCM. Because battery voltage is applied to TCM
even if ignition switch is turned off.
When connecting or disconnecting pin connectors into or
from TCM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on TCM
pin terminal, when connecting pin connectors.
Before replacing TCM, perform TCM input/output signal
inspection and make sure whether TCM functions properly
or not. (See page AT- 7 8 , "
TCM Terminals and Reference
Va l u e".)
After performing each TROUBLE DIAGNOSIS, perform
“DTC (Diagnostic Trouble Code) Confirmation Procedure”.
The DTC should not be displayed in the “DTC Confirmation
Procedure” if the repair is completed.
Before proceeding with disassembly, thoroughly clean the out-
side of the transaxle. It is important to prevent the internal parts
from becoming contaminated by dirt or other foreign matter.
Disassembly should be done in a clean work area.
Use lint-free cloth or towels for wiping parts clean. Common shop rags can leave fibers that could interfere
with the operation of the A/T.
Place disassembled parts in order for easier and proper assembly.
All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.

Occasionally, certain portions of the self-diagnostic test may not be completed as a result of the customer's
normal driving pattern; the SRT will indicate “INCMP” for these items.
NOTE:
The SRT will also indicate “INCMP” if the self-diagnosis memory is erased for any reason or if the ECM mem-
ory power supply is interrupted for several hours.
If, during the state emissions inspection, the SRT indicates “CMPLT” for all test items, the inspector will con-
tinue with the emissions test. However, if the SRT indicates “INCMP” for one or more of the SRT items the
vehicle is returned to the customer untested.
NOTE:
If MIL is ON during the state emissions inspection, the vehicle is also returned to the customer untested even
though the SRT indicates “CMPLT” for all test items. Therefore, it is important to check SRT (“CMPLT”) and
DTC (No DTCs) before the inspection.
SRT Item
The table below shows required self-diagnostic items to set the SRT to “CMPLT”.
*: If completion of several SRTs is required, perform driving patterns (DTC confirmation procedure), one by one based on the priority for
models with CONSULT-II.
SRT Set Timing
SRT is set as “CMPLT” after self-diagnosis has been performed one or more times. Completion of SRT is
done regardless of whether the result is OK or NG. The set timing is different between OK and NG results and
is shown in the table below.

10. DETECT MALFUNCTIONING PART BY DIAGNOSTIC PROCEDURE
Inspect according to Diagnostic Procedure of the system.
NOTE:
The Diagnostic Procedure in EC section described based on open circuit inspection. A short circuit inspection
is also required for the circuit check in the Diagnostic Procedure. For details, refer to Circuit Inspection in GI-
27, "How to Perform Efficient Diagnosis for an Electrical Incident" .
Is malfunctioning part detected?
Yes >> GO TO 11.
No >> Monitor input data from related sensors or check voltage of related ECM terminals using CON-
SULT-II. Refer to EC-105, "
ECM Terminals and Reference Value" , EC-128, "CONSULT-II Refer-
ence Value in Data Monitor" .
11 . REPAIR OR REPLACE THE MALFUNCTIONING PART
1. Repair or replace the malfunctioning part.
2. Reconnect parts or connectors disconnected during Diagnostic Procedure again after repair and replace-
ment.
3. Check DTC. If DTC is displayed, erase it, refer to EC-60, "
HOW TO ERASE EMISSION-RELATED DIAG-
NOSTIC INFORMATION" .
>> GO TO 12.
12. FINAL CHECK
When DTC was detected in step 2, perform DTC Confirmation Procedure or Overall Function Check again,
and then make sure that the malfunction have been repaired securely.
When symptom was described from the customer, refer to confirmed symptom in step 3 or 4, and make sure
that the symptom is not detected.
OK or NG
NG (DTC*1 is detected)>>GO TO 10.
NG (Symptom remains)>>GO TO 6.
OK >> 1. Before returning the vehicle to the customer, make sure to erase unnecessary DTC*
1 in ECM
and TCM (Transmission Control Module). (Refer to EC-60, "
HOW TO ERASE EMISSION-
RELATED DIAGNOSTIC INFORMATION" and AT-39, "OBD-II Diagnostic Trouble Code
(DTC)" , CVT-30, "OBD-II Diagnostic Trouble Code (DTC)" .)
2. If the completion of SRT is needed, drive vehicle under the specific driving pattern. Refer to EC-
57, "Driving Pattern" .
3.INSPECTION END
*1: Include 1st trip DTC.
*2: Include 1st trip freeze frame data.
DIAGNOSTIC WORKSHEET
Description
There are many operating conditions that lead to the malfunction of
engine components. A good grasp of such conditions can make trou-
bleshooting faster and more accurate.
In general, each customer feels differently about a incident. It is
important to fully understand the symptoms or conditions for a cus-
tomer complaint.
Utilize a diagnostic worksheet like the one on the next page in order
to organize all the information for troubleshooting.
Some conditions may cause the MIL to come on steady or blink and
DTC to be detected. Examples:
Vehicle ran out of fuel, which caused the engine to misfire.
Fuel filler cap was left off or incorrectly screwed on, allowing fuel
to evaporate into the atmosphere.
