STOPLIGHT SWITCH CHECK
1. Connect an ohmmeter between the stoplight switch
connector terminals.
2. There should be no continuity between the terminals when
the plunger is pushed in as shown. There should be
continuity when it is released.

TRACTION CONTROL SYSTEM (TCL) DIAGNOSIS
TRACTION CONTROL SYSTEM (TCL)13C-23
SYMPTOM CHARTM1136003400029
SYMPTOM PROCEDURES
INSPECTION PROCEDURE 1: When the Ignition Switch is Turned to the "ON" Position
(Engine Stopped), the "TCL OFF" Indicator Light does not Illuminate. INSPECTION
PROCEDURE 2: When the Ignition Switch is Turned to the "ON" Position (Engine
Stopped), the TCL Work Indicator Light dose not Illuminate. INSPECTION
PROCEDURE 3: The "TCL OFF" Indicator Light Remains Illuminated After the Engine
is Started. INSPECTION PROCEDURE 4: The TCL Work Indicator Light Remains
Illuminated After the Engine is Started.

TRACTION CONTROL SYSTEM (TCL) DIAGNOSIS
TRACTION CONTROL SYSTEM (TCL)13C-36
DATA LIST REFERENCE TABLEM1136003500071
NOTE: If the ABS-8 ECU or the active wheel
speed sensor are disconnected, or if the wiring is
an open/ short circuit, the ABS 8 ECU will shut
off power supply to the respective wheel speed
sensor. All other wheel speed sensors will oper-
ate normally. To restore the power supply, the
ignition switch must be turned to the "OFF" posi-
tion then to the "ON" position again.The following items can be read by the diagnostic
tool from the ABS/TCL-ECU input data. (Refer to
P.13C-3).
NOTE: Since the TCL is controlled with the same ABS/TCL-ECU used to control the ABS, the stoplight switch
check item (No.6) used only for the ABS also appear.MUT-III

When shifting the selector lever to "D" range, apply the brakes so that the vehicle does not move
forward.
Driving tests always need two persons: one driver and one observer.
NOTE: *:After the inspection is completed, disconnect the throttle position sensor connector, and then delete
the diagnostic trouble code using use of Diagnostic Tool MB991958. (Refer to P.17-11).

AUTO-CRUISE CONTROL SWITCH CHECK
1. Remove the auto-cruise control switch. (Refer to P.17-75).
2. Measure the resistance between terminal 2 and terminal 3
when each of the "COAST/SET", "ACC/RES", "CANCEL"
and "CRUISE" (MAIN) switches is pressed. If measure
values measured at the time correspond to those in the table
below, the resistance values are correct.
