Precautions

Precautions in Diagnosing Trouble

S5JB0E5100001

• Do not disconnect couplers from TCM, battery cable 

from battery, TCM ground wire harness from engine or 
main fuse before checking the diagnostic information 
(DTC, freeze frame data, etc.) stored in TCM memory. 
Such disconnection will clear memorized information 
in TCM memory.

• For vehicle without engine diagnosis connector, 

diagnostic information stored in TCM memory can be 
cleared as well as checked by using SUZUKI scan 
tool or OBD generic scan tool. Before using scan tool, 
read its Operator’s (Instruction) Manual carefully to 
have good understanding as to what functions are 
available and how to use it.
It is indistinguishable which module turns on MIL 
because not only ECM but also TCM turns on MIL. 
Therefore, check both ECM and TCM for DTC when 
MIL lights on.
When checking TCM for DTC, keep in mind that DTC 
is displayed on the scan tool as follows depending on 
the scan tool used.
– SUZUKI scan tool displays DTC detected by TCM.
– OBD generic scan tool displays DTC detected by 

each of ECM and TCM simultaneously.

• For vehicle with engine diagnosis connector, using 

SUZUKI scan tool the diagnostic information stored in 
TCM memory can be checked and cleared as well. 
Before its use, be sure to read Operator’s Manual 
supplied with it carefully to have good understanding 
of its functions and usage.

• Not using scan tool (if equipped with AT monitor 

connector), the DTC stored in TCM memory also can 
be checked and cleared. DTC stored in the TCM 
memory is outputted by displaying DTC on digital 
display odometer with diagnosis terminal of monitor 
connector grounded. If no DTC is stored in TCM 
memory, DTC 0000 is outputted. If one or more DTCs 
are stored in TCM memory, they are outputted starting 
from smallest code number in increasing order. After 
all DTCs are outputted, all DTCs are outputted 
repeatedly.

• Be sure to read “Precautions for Electrical Circuit 

Service in Section 00 in related manual” before 
inspection and observe what is written there.

• TCM and/or ECM replacement:

When substituting a known-good TCM and/or ECM, 
check for the following conditions.
Neglecting this check may result in damage to a good 
TCM and/or ECM.
– All relays and actuators have resistance of 

specified value.

– MAF sensor, Manifold absolute pressure (MAP) 

sensor, TP sensor and fuel tank pressure sensor 
are in good condition. Also, the power circuit of 
these sensors is not shorted to the ground.

• Communication of ECUs, ECM, TCM, BCM, 

combination meter, 4WD control module (if equipped), 
ABS/ESP

® control module, keyless start control 

module (if equipped), steering angle sensor (if 
equipped) and DLC is established by CAN (controller 
Area Network). For more detail of CAN 
communication, refer to “CAN Communication 
System Description”. Therefore, handle CAN 
communication line with care referring to “Precaution 
for CAN Communication System in Section 00 in 
related manual”.

General Description

Automatic Transmission Description

S5JB0E5101001

This automatic transmission is a full automatic type with 3-speed plus overdrive (O/D).
The torque converter is a 3-element, 1-step and 2-phase type and is equipped with an electronically controlled lock-up 
mechanism. The gear shift device consists of 3 sets of planetary gear units,3 disc type clutches, 4 disc type brakes 
and 3 one-way clutches. The gear shift is done by selecting one of 7 positions (“P”, “R”, “N”, “D”, “3”, “2” and “L”) by 
means of the select lever installed on the floor. Also, by using the P/N mode switch located on the console box, it is 
possible to select the gear change timing of 2 modes, normal and power.
