3. Vehicles for AWD, connect special tool MB991970 between the
TCL/ASC-ECU and the body-side harness connector.
4. Turn the ignition switch to the "ON" position.
5. Vehicles for FWD, measure the terminal voltage between special tool
MB991970 connector terminal 6 (ABS/TCL-ECU connector A-02
terminal 6) and ground.
When the TCL switch is not pressed, the voltage should measure
battery positive voltage (approximately 12 volts). When the TCL switch is pressed, the voltage should measure 1 volt or
less.
6. Vehicles for AWD, measure the terminal voltage between special tool
MB991952 connector terminal 15 (TCL/ASC-ECU connector A-32
terminal 15) and ground. When the TCL switch is not pressed, the voltage should measure
battery positive voltage (approximately 12 volts). When the TCL switch is pressed, the voltage should measure 1 volt or
less.
7. Turn the ignition switch to the "LOCK" (OFF) position.
8. Vehicles for FWD, disconnect special tool MB991970 between the
ABS/TCL-ECU and the body-side harness connector.
9. Vehicles for AWD, disconnect special tool MB991952 between the
TCL/ASC-ECU and the body-side harness connector.
10. Connect all the connectors from the ABS/TCL-ECU < FWD > or
TCL/ASC-ECU < AWD >.

STEP 2. Check the TCL switch.
1. Remove the TCL switch. (Refer to TCL SWITCH
).
2. Connect an ohmmeter to the TCL switch between terminals 1 and 2.
3. Check for continuity between terminals 1 and 2 when the TCL switch is
operated.
There is no continuity between terminals 1 and 2 when the TCL
switch is not pressed. There is continuity between terminals 1 and 2 when the TCL switch is
pressed.
Q: Is there no continuity between terminals 1 and 2 when the TCL switch
is not pressed, and is there continuity when the TCL switch is pressed?
YES: Install the TCL switch. (Refer to TCL SWITCH
). Then go to Step 6 .
NO
: Re
place the TCL switch.
(Refer to TCL SWITCH
). Then
go to Ste
p 7 .

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
