TROUBLESHOOTING
TRACTION CONTROL/ACTIVE STABILITY CONTROL SYSTEM
35C-110
CAUTION
• If diagnosis code No.U1101 is set in the
TCL/ASC-ECU, always diagnose the CAN
main bus line. If there is any fault in the CAN
bus lines, an incorrect diagnosis code may be
set.
• Whenever the ECU is replaced, ensure that
the communication circuit is normal.
DIAGNOSIS CODE SET CONDITION
The TCL/ASC-ECU receives A/T system-related
signals from the Engine-A/T-ECU via CAN bus lines.
PROBABLE CAUSES
• Damaged harness or connector.
• Malfunction of the Engine-A/T-ECU.
• Malfunction of the TCL/ASC-ECU.
DIAGNOSIS
STEP 1. MUT-III CAN bus diagnostics
CAUTION
To prevent damage to MUT-III, always turn the
ignition switch to the "LOCK" (OFF) position
before connecting or disconnecting MUT-III.
(1) Connect the MUT-III to the diagnosis connector
as shown in the illustration.
(2) Turn the ignition switch to the "ON" position.
(3) Diagnose the CAN bus line. (Refer to GROUP
54D, CAN bus line Diagnostic flow
).
(4) Turn the ignition switch to the "LOCK" (OFF)
position.
(5) Disconnect MUT-III.
Q: Is the check result normal?
YES :
Go to Step 2 .
NO :
Repair the CAN bus line (Refer to GROUP
54D, CAN bus line Diagnostic flow
). Then go to Step 2.
STEP 2. MUT-III other system diagnosis code
CAUTION
To prevent damage to MUT-III, always turn the
ignition switch to the "LOCK" (OFF) position
before connecting or disconnecting MUT-III.
(1) Connect the MUT-III to the diagnosis connector
as shown in the illustration.
(2) Turn the ignition switch to the "ON" position.
(3) Check for A/T system diagnosis code (Refer to
GROUP 23A, A/T Diagnosis - Diagnosis Function
(4) Turn the ignition switch to the "LOCK" (OFF)
position.
(5) Disconnect MUT-III.
Q: Is any diagnosis code set?
YES :
Repair the automatic transmission control
system. (Refer to GROUP 23A, A/T
Diagnosis - Check Chart For Diagnosis
Codes
). Then go to Step 6 .
NO :
Go to Step 3 .
