DTC P1603: TCM Trouble Code Detected
S4RS0A1104065
Wiring Diagram
DTC Detecting Condition
When ECM receives a trouble code from TCM, which indicates that some problem occurred in sensor circuits and its
calculated values used for operations such as idle speed control, engine power control, and so on by TCM, ECM sets
DTC P1603. (TCM outputs the trouble code to ECM when TCM can not compute the engine control signal due to
malfunctions of sensor circuits used for gear shift control.)
DTC Troubleshooting
NOTE:
• Before performed trouble shooting, be sure to read the “Precautions of ECM Circuit Inspection: ”.
• When measuring circuit voltage, resistance and/or pulse signal at ECM connector, connect the
special tool to ECM and/or the ECM connectors referring to “Inspection of ECM and Its Circuits: ”.
• Upon completion of inspection and repair work, perform “DTC Confirmation Procedure” and
confirm that the trouble has been corrected.

Battery voltage supply circuit check
1) Turn OFF ignition switch.
2) Remove ECM from its bracket with ECM connectors
connected.
3) With engine running, measure voltage between “E23-2”
terminal of ECM connector and engine ground.
Is voltage 10 – 14 V?
Poor “E23-2”
connection or
intermittent trouble.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection: in Section
00”.
If wire and connections
are OK, substitute a
known-good ECM and
recheck.
“RADIO” fuse blown,
“WHT” or “WHT/RED”
wire is open or short
circuit.
