DTC Check

NOTE
For vehicle without engine diagnosis
connector, the MIL is turned on when the
ECM and/or TCM detect malfunction(s). Each
ECU stores diagnostic information as the
diagnostic trouble code (DTC) in its memory
and outputs the DTC to the scan tool.
Therefore, check both of the ECUs for any
DTC with the scan tool because the DTC
stored in ECU and TCM is not read and
displayed at a time. However, each of the
ECUs needs not to be checked with the
generic scan tool because the DTC stored in
ECM and TCM is read and displayed at a time.
Automatic transmission DTC can be checked using any
one of the following 2 methods.

Detecting condition (DTC will set when
detecting)
Voltage of shift solenoid terminal is low although
TCM is commanding shift solenoid to turn ON.
Voltage of shift solenoid terminal is high although
TCM is commanding shift solenoid to turn OFF.
Calculation of current data stored in TCM is not
correct comparing with pre-stored checking data
in TCM.
TCM receives malfunction signal of throttle
position, engine coolant temperature, engine
revolution and engine torque from ECM.
value.
Transmitting error detected to TCM for specified
time continuously.
Receiving error from ECM detected to TCM for
specified time continuously.
Receiving error from BCM detected to TCM for
specified time continuously.
Actual transfer position is 4H although transfer
low signal is inputted.
Actual transfer position is 4L or N although
transfer low signal is not inputted.
Variation in the output revolution speed of the
specified amplitude and specified cycle is
detected under slip lock-up condition.
Too much electric flow is detected on TCC
pressure control solenoid circuit.
No electric flow is detected on TCC pressure
control solenoid circuit.
Reading DTC Using SUZUKI Scan Tool
S5JB0A5104006
1) Turn ignition switch OFF.
2) Connect SUZUKI scan tool to data link connector
(DLC).
