SYSTEM CHECK SOUND When starting the engine, a thudding sound can sometimes be heard coming from
the engine compartment. This is a normal sound during the TCL/ASC self-check. TCL/ASC OPERATION SOUNDS AND SENSATIONS During normal operation, the TCL/ASC makes several sounds that may seem
unusual at first:

TRACTION CONTROL SYSTEM OPERATION The TCL/ASC-ECU receives information from the PCM, the G and yaw-rate
sensor, and the wheel speed sensor. If the ECU determines that a road wheel is
spinning, it will control the fluid pressure to the spinning wheel to apply torque to
the other road wheels. The operations of the ABS solenoid valves and the active
skid control system valves are the same as for the active skid control system.
Furthermore, the system also controls the engine if the accelerator pedal is
depressed excessively. TCL/ASC DIAGNOSIS INTRODUCTION TO TRACTION CONTROL/ACTIVE SKID CONTROL SYSTEM DIAGNOSIS The traction control/active skid control system (TCL/ASC) is a system that has
added the cut valve and suction valve to the conventional ABS system. These
valves are used to control each of the road wheels independently. These differences
include sounds, sensations, and vehicle performance that owners and service
technicians who are not familiar with TCL/ASC may not be used to.
Some operational characteristics may seem to be malfunctions, but they are simply
signs of normal TCL/ASC operation. When diagnosing the TCL/ASC system, keep
these operational characteristics in mind. Inform the owner of the kind of
performance characteristics to expect from an TCL/ASC-equipped vehicle. TCL/ASC Diagnostic Trouble Code Detection Conditions TCL/ASC diagnostic trouble codes (TCL/ASC DTCs) are set under different
conditions, depending on the malfunction detected. Most TCL/ASC DTCs will only
be set during vehicle operation. Some TCL/ASC DTCs will also be set during the
TCL/ASC self-check immediatel
y after the en
gine is started.
NOTE: *: When the ASC is operating while the brake pedal is
depressed, the suction valve turns on and off according to
the brake fluid amount supplied to the buffer chamber.

When you check if an TCL/ASC DTC will be displayed again after the DTC has
been erased, you should duplicate the TCL/ASC DTC set conditions. Depending on
the detection timing and set conditions for the specific TCL/ASC 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/ASC DTC SET CONDITIONS
" for
each TCL/ASC DTC that you are trying to reset.
TCL/ASC DIAGNOSTIC TROUBLESHOOTING STRATEGY Use these steps to plan your diagnostic strategy. If you follow them carefully, you
will be sure that you have exhausted most of the possible ways to find an TCL/ASC
fault.
1. Gather information about the problem from the customer.
2. Verify that the condition described by the customer exists.
3. Check the vehicle for any TCL/ASC DTC.
4. If you cannot verify the condition and there are no TCL/ASC DTCs, the
malfunction is intermittent. Refer to HOW TO COPE WITH
INTERMITTENT MALFUNCTIONS
.
5. If you can verify the condition but there are no TCL/ASC DTCs, or the system
cannot communicate with the scan tool, check that the basic brake system is
operating properly.
If the basic brake system is not operating properly, refer to the BASIC BRAKE SYSTEM DIAGNOSIS
, .
If the basic brake system is operating properly, refer to SYMPTOM CHART
.
6. If there is an TCL/ASC DTC, record the number of the DTC, then erase the
DTC from the memory using the scan tool.
7. Duplicate the TCL/ASC DTC set conditions to see if the same TCL/ASC DTC
will set again.
If the same TCL/ASC DTC sets again or the TCL/ASC DTC cannot be
erased, perform the diagnostic procedures for the DTC. Refer to
DIAGNOSTIC TROUBLE CODE CHART
.
If you cannot
get the same TCL/ASC DTC to set a
gain, the malfunction is

12. After inspection, disconnect scan tool MB991958 immediately after turning the
ignition switch to the "LOCK" (OFF) position.
IN THE EVENT OF A DISCHARGED BATTERY If the engine is started using a booster cable when the battery is completely flat, and
the vehicle is then driven without waiting for the battery to be recharged, the engine
may misfire and it may not be possible to drive the vehicle. This is because the ABS
consumes a large amount of current when carrying out its initial checks. If this
happens, recharge the battery fully.
WARNING:If the ABS is not operating, the vehicle will be
unstable during braking, Do not drive the vehicle
with the TCL/ASC-ECU connector disconnected or
with the TCL/ASC not operating for any other
reason.

Starters - Endeavor
DESCRIPTION & OPERATION If the ignition switch is turned to START position, current flows in the coil
provided inside magnetic switch, attracting the plunger. When plunger is attracted,
the lever connected to plunger is actuated to engage starter clutch. On the other
hand, attracting plunger will turn on magnetic switch, allowing "B" terminal and
"M" terminal to conduct. Thus, current flows to engage starter motor. When
ignition switch is returned to ON position after starting engine, starter clutch is
disengaged from ring gear.
An overrunning clutch is provided between pinion and armature shaft to prevent
damage to starter.
When the ignition switch is switched to the START position while the selector leve
r
is at the "P" or "N" range, the contact (magnetic switch) of the starter is switched
ON and the starter motor is activated.
ADJUSTMENT PINION GAP 1. Disconnect the field coil wire from the "M" terminal of magnetic switch.
2. Connect a 12V battery between "S" terminal and "M" terminal. See Fig. 1
.
3. Set switch to ON and pinion will move out.
4. Check the pinion to stopper clearance (pinion gap) with a feeler gauge. See
Fig. 2
.
5. If the pinion gap is out of specification, adjust by adding or removing gasket(s)
between the ma
gnetic switch and front bracket. CAUTION: To prevent coil from burning, DO NOT apply voltage
to starter assembly for more than 10 seconds.
