3. Check the rubber hangers and brackets for damage.
9. ENGINE OIL (CHANGE)M1001002600360
Use the specified oil. (Refer to P.00-35.)
Use care as oil could be hot.
1. After warming up the engine, remove the oil filler cap.
2. Remove the drain plug to allow the engine oil to drain.
3. Install a new drain plug gasket so that it faces in the
direction shown in the illustration, and then tighten the drain
plug to the specified torque.
Tightening torque: 39
5 Nm (29 3 ft-lb)
4. Pour new engine oil in through the oil filler hole.
Specified Engine Oil:
To ta l q u a n t i t y :
<3.8L Engine> 4.6 Litres
5. Install the engine oil filler cap.
6. Start the engine and run it at idle for a few minutes.
7. Pull out the oil dipstick slowly and check that the oil level is
within the marks on the oil dipstick.
8. Check that the oil is not excessively dirty, that there is no
coolant or petrol mixed in, and that it has sufficient viscosity.
10. ENGINE OIL FILTER (REPLACE)M1001002700345
The quality of replacement filters varies considerably. Only high
quality filters should be used to assure most efficient service.
Genuine oil filters require that the filter is capable of withstand-
ing a pressure of 1,800 kPa (261 psi) are high quality filters.

INTRODUCTION TO TRACTION CONTROL SYSTEM (TCL) DIAGNOSISM1136004600026
TCL Diagnostic Trouble Code Detection
Conditions
TCL diagnostic trouble codes (TCL DTCs) are set
under different conditions, depending on the mal-
function 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 condi-
tions. 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.
TROUBLESHOOTING STRATEGYM1136003100062
Use these steps to plan your diagnostic strategy. If
you follow them carefully, you will check most of the
possible causes of a TCL problem.
1. Gather information from the customer.
2. Verify that the condition described by the
customer exists.
3. Check the vehicle for any TCL DTC. (Refer to
P.13C-3, Diagnosis Function
How to Read and
Erase Diagnostic Trouble Codes).
4. If you can verify the condition but no TCL DTCs
are set, and the malfunction may be intermittent.
(Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points
How
to Cope with Intermittent Malfunctions P.00-14).
5. If you can verify the condition but there is no TCL
DTCs, or the system cannot communicate with
diagnostic tool MB991958 (MUT-III sub
assembly), and find the fault. (Refer to P.13C-23,
Symptom Chart).6. If there is a TCL DTC, record the number of the
code, then erase the code from vehicle memory
using the diagnostic tool MB991958 (MUT-III sub
assembly). (Refer to P.13C-3, Diagnosis Function
How to Read and Erase Diagnostic Trouble
Codes).
7. Re-create the TCL DTC set conditions to see if
the same TCL DTC will set again. (Refer to
P.13C-3, Diagnosis Function
How to Read and
Erase Diagnostic Trouble Codes).
If the same TCL DTC sets again, perform the
diagnostic procedures for the set code. (Refer to
P.13C-8, Diagnostic Trouble Code Chart).
NOTE: If the ABS-8 ECU or the active wheel
speed sensor are disconnected, or if the wir-
ing 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 operate normally. To restore the
power supply, the ignition switch must be
turned to the "OFF" position then to the "ON"
position again.

STEP 4. Retest the system
Q: Turn the ignition switch to the "ON" position. Do the
"TCL OFF" indicator light and the TCL work indicator
light illuminate for three seconds, and then go out after
the engine starts?
YES : The procedure is complete.
NO : . Return to Step 1.
INSPECTION PROCEDURE 5: When the TCL Switch is Pushed On, TCL does not Cancel.
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.
.
CIRCUIT OPERATION
ABS/TCL-ECU terminal 21 is grounded every time
the TCL switch is pressed. ABS/TCL-ECU monitors
this operation state and turns the TCL ON or OFF.
.
COMMENT
The cause is probably an open-circuit in the TCL
switch circuit.
