CIRCUIT OPERATION ABS/TCL-ECU terminal 6 < FWD > or TCL/ASC-ECU terminal 15 < AWD > is
grounded every time the TCL switch is pressed. ABS/TCL-ECU < FWD > or
TCL/ASC-ECU < AWD > monitors this operation state and turns the TCL system
ON or OFF. COMMENT The cause is probably an open-circuit in the TCL switch circuit. TROUBLESHOOTING HINTS
Malfunction of the TCL switch Damaged harness, connector Malfunction of the ABS/TCL-ECU < FWD > or TCL/ASC-ECU < AWD >

TROUBLESHOOTING HINTS (THE MOST LIKELY CAUSES FOR THIS CASE:)
Malfunction of the CAN bus line. Malfunction of the MFI system. Malfunction of the A/T system. Malfunction of the ABS/TCL-ECU < FWD > or TCL/ASC-ECU < AWD >.
DIAGNOSIS
Required Special Tool:
MB991958: Scan tool (MUT-III sub assembly)
MB991824: V.C.I. MB991827: MUT-III USB cable MB991910: MUT-III main harness A
STEP 1. Using scan tool MB991958, read the diagnostic trouble code.
1. Connect scan tool MB991958 to the data link connector. (Refer to
TRACTION CONTROL SYSTEM (TCL) DIAGNOSIS
).
2. Turn the ignition switch to the "ON" position.
3. Use scan tool MB991958 to read the TCL diagnostic trouble codes.
4. Turn the ignition switch to the "LOCK" (OFF) position.
5. Disconnect scan tool MB991958.
Q: Is any DTC set?
YES: Repair the TCL system. (Refer to TCL DIAGNOSTIC TROUBLE
CODE CHART

1. Connect scan tool MB991958 to the data link connector. (Refer to
TRACTION CONTROL SYSTEM (TCL) DIAGNOSIS ).
2. Turn the ignition switch to the "ON" position.
3. Use scan tool MB991958 to check the actuator test.
Item 09: Engine TCL Drive.
When the accelerator pedal is depressed at the same time that the
button for actuator test item 09 displayed on scan tool
MB991958 is pressed, the system prevents the engine speed from
rising for three seconds.
4. Turn the ignition switch to the "LOCK" (OFF) position.
5. Disconnect scan tool MB991958.
Q: Are the check results for actuator test item 09 satisfactory?
YES: Go to Step 3.
NO: Replace the hydraulic unit (integrated with ABS/TCL-ECU < FWD > or
TCL/ASC-ECU < AWD >). (Refer to HYDRAULIC UNIT
). Then go to Step
4 .
STEP 3. Retest the system
Q: Does the TCL system work normally?
YES: It can be assumed that this malfunction is intermittent. (Refer to HOW
TO COPE WITH INTERMITTENT MALFUNCTIONS
).
NO: Replace the hydraulic unit (integrated with ABS/TC
L-ECU < FWD > or CAUTION: The engine speed increases after the
actuator test because the actuator test
continues for only three seconds. Therefore,
release the accelerator pedal immediately.

2. Check that the "TCL OFF" indicator light illuminates and goes off in cycles
each time the TCL switch is pushed after starting the engine.
3. Check that the "TCL OFF" indicator light and the TCL work indicator light do
not illuminate, when driving at 30km/h (37.5 mph) for more than 2 seconds.
4. If defective, repair it (Refer to TRACTION CONTROL/ACTIVE SKID
).
