STEP 3. Check ABS/TCL-ECU connector A-02 < FWD > or TCL/ASC-
ECU connector A-32 < 4AWD >, intermediate connector C-31 and TCL
switch connectors C-35 for loose, corroded or damaged terminals, or
terminals pushed back in the connector.
Q: Are there connectors and terminals in good condition?
YES: Go to Step 4.
NO: Re
pair or re
place the fault
y connector.
(Refer to
). Then
go to Ste
p 7 .

STEP 4. Check the harness wire between ABS/TCL-ECU connector A-02
terminal 6 < FWD > or TCL/ASC-ECU connector A-32 terminal 15 <
AWD > and TCL switch connector C-35 terminal 1 for damage.
Q: Are there harness wires in good condition?
YES: Go to Step 5.
NO: Repair the damaged harness wire. Then go to Step 7 .

STEP 6. Retest the system
Q: Is TCL system cancelled when the TCL switch is push on?
YES: It can be assumed that this malfunction is intermittent. (Refer to ).
NO: Replace the hydraulic unit (integrated with ABS/TCL-ECU < FWD > or
TCL/ASC-ECU < AWD >). (Refer to HYDRAULIC UNIT ). Then go to Step
7.
STEP 7. Retest the system
Q: Does TCL system cancelled, when the TCL switch is push on?

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
). Then go to Step 4 . CAUTION: To prevent damage to scan tool MB991958,
always turn the ignition switch to the
"LOCK" (OFF) position before connecting or
disconnecting scan tool MB991958.

.
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.

TCL/ASC-ECU < AWD >). (Refer to HYDRAULIC UNIT
). Then go to Step
4.
STEP 4. Retest the system
Q: Does the TCL system work normally?
YES: The procedure is complete.
NO: Return to Step 1 .
DATA LIST REFERENCE TABLE The following items can be read by the scan tool from the ABS/TCL-ECU < FWD

CHECK AT ABS/TCL-ECU TERMINAL VOLTAGE & TERMINAL VOLTAGE CHECK CHART Required Special Tool:
MB991970: ABS check harness
1. Disconnect the ABS/TCL-ECU connector A-02 and connect special tool
MB991970 between the ABS/TCL-ECU and the body-side harness connector.
Then use special tool MB991970 to measure the voltages between terminal 2
and each terminal.
2. The terminal la
youts are shown in the illustrations below.

RESISTANCE AND CONTINUITY BETWEEN HARNESS-SIDE CONNECTOR TERMINALS Required Special Tool:
MB991970: ABS check harness
1. Disconnect the ABS/TCL-ECU connector A-02 and connect special tool
MB991970 to the A-02 body-side harness connector. Then turn the ignition
switch to the "LOCK"
(OFF
) position and checkin
g resistance and continuit
y.
NOTE: Do not measure terminal voltage for approximately three
seconds after the ignition switch is turned "ON". The
ABS/TCL-ECU performs the initial check during that period.
