TSB Revision

TRACTION CONTROL SYSTEM (TCL)

35C-3

System Check Sound
When starting the engine and moving the vehicle for 
the first time after startup, a thudding sound can 
sometimes be heard coming from the engine 
compartment. This is a normal sound during the ABS 
and TCL unit self-check.

ABS Operation Sounds and Sensations
During normal operation, the ABS makes several 
sounds that may seem unusual at first:
A whining sound is caused by the ABS hydraulic unit 
motor.

TCL DIAGNOSTIC TROUBLE CODE DETECTION CONDITIONS

M1354003500048

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.

the data link connector.

CAUTION

Do not depress the brake pedal after the ignition switch is 
turned "ON." If the brake pedal is depressed while the ABS

trouble codes will not be read out.
2. Turn the ignition switch to the "ON" position.
3. Read out a diagnostic trouble code by observing how the 

warning light flashes.

4. Disconnect special tool MB991529.
