TRACTION CONTROL SYSTEM (TCL) DIAGNOSIS INTRODUCTION TO TRACTION CONTROL SYSTEM (TCL) DIAGNOSIS TCL DIAGNOSTIC TROUBLE CODE DETECTION CONDITIONS TCL diagnostic trouble codes (TCL DTCs) are set under different conditions,
depending on the malfunction detected. Most TCL DTCs will only be set during
vehicle operation. Some TCL DTCs will also be set during the TCL self-check
immediately after the engine is started. When you check if an TCL DTC will be
displayed again after the DTC has been erased, you should recreate the TCL DTC
set conditions. Depending on the detection timing and set conditions for the specific
TCL DTC, you must either drive the vehicle or turn the engine off and restart it. To
set the proper conditions for that DTC again, refer to "TCL DTC SET
CONDITIONS" for each TCL DTC that you are trying to reset. TCL DIAGNOSTIC TROUBLESHOOTING STRATEGY Use these steps to plan your diagnostic strategy. If you follow them carefully, you
will check most of the possible causes of a TCL problem.
1. Gather information from the customer.
2. Verify that the condition described by the customer exists.
3. Check the vehicle for any TCL DTC.
4. If you can verify the condition but no TCL DTCs are set, and the malfunction
may be intermittent. Refer to HOW TO COPE WITH INTERMITTENT
MALFUNCTIONS

5. If you can verify the condition but there is no TCL DTCs, or the system cannot
communicate with scan tool MB991958 (MUT-III sub assembly), refer to
SYMPTOM CHART , and find the fault.
6. If there is a TCL DTC, record the number of the code, then erase the code from
vehicle memory using scan tool MB991958 (MUT-III sub assembly).
7. Re-create the TCL DTC set conditions to see if the same TCL DTC will set
again.
If the same TCL DTC sets again, perform the diagnostic procedures for
the set code. Refer to TCL DIAGNOSTIC TROUBLE CODE

Q: Is DTC U1101 set?
YES: Return to Step 1 .
NO: The procedure is complete.
DTC U1120: CAN Communications System TCL Uncontrollable by Engine Malfunction DTC SET CONDITION The ABS/TCL-ECU < FWD > or TCL/ASC-ECU < AWD > receives engine
system-related signals from the powertrain control module (PCM) via CAN bus
lines. If a fail-safe related data is contained in the si
gnal from the PCM, DTC CAUTION:
If DTC U1120 is set in the ABS/TCL-ECU < FWD >
or TCL/ASC-ECU < AWD >, always diagnose the
CAN main bus line. If there is any fault in the
CAN bus lines, an incorrect DTC may be set. Whenever the ABS/TCL-ECU < FWD > or
TCL/ASC-ECU < AWD > is replaced, ensure that
the communication circuit is normal. The engine control system-related DTC may be
set when DTC U1120 is set. Diagnose the engine
control system first when the engine control
system-related DTC is set.
