PRECAUTIONS
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.
