5. When the repair work is completed, return the ignition switch to the ″LOCK ″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of al l control units using CONSULT-III.
Precaution for On Board Diagnosis (OBD) System of A/T and EngineINFOID:0000000003772014
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 sw itch “OFF” and disconnect the negati ve battery cable before any repair
or inspection work. The open/short circuit of related switches, sensors, solenoid valves, etc. Will
cause the MIL to light up.
 Be sure to connect and lock the connectors secure ly after work. A loose (unlocked) connector will
cause the MIL to light up due to an open circuit. (Be sure the connector is 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 li ght up due to a short circuit.
 Be sure to connect rubber tubes properly afte r work. A misconnected or disconnected rubber tube
may cause the MIL to light up due to a malfunction of the EGR system or fuel injection system, etc.
 Be sure to erase the unnecessary malfunction informa tion (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.
PrecautionINFOID:0000000003772015
NOTE:
If any malfunctions occur in th e RE5R05A model transmission, repl ace the entire transmission assem-
bly.
 Before connecting or disconn ecting the TCM harness connec-
tor, turn ignition switch “O FF” and disconnect negative bat-
tery cable. Because battery voltage is applied to TCM even if
ignition switch is turned “OFF”.
 After performing each TROUBL E DIAGNOSIS, perform “DTC
(Diagnostic Trouble Code) CONFIRMATION PROCEDURE”.
If the repair is completed the DTC should not be displayed in the
“DTC CONFIRMATION PROCEDURE”.
 Always use the specified brand of ATF. Refer to MA-12, "Fluids and Lubricants"
.
 Use paper rags not cloth rags during work.
 After replacing the ATF, dispose of the waste oil using the methods prescribed by law, ordinance, etc.
 Before proceeding with disassembly, thoroughly clean the outsi de of the transmission. It is important to pre-
vent 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 transmission.
 Place disassembled parts in order for easier and proper assembly.
