The TCL/ASC-ECU gathers information regarding lateral and longitudinal
accelerations and yaw rate, through the CAN bus line from the G and yaw rate
sensor. TCL/ASC DTC SET CONDITIONS The TCL/ASC-ECU activates the G and yaw rate sensor via a CAN bus line in
order to diagnose the sensor whenever the ignition switch is turned on. If the G and
yaw rate sensor does not respond to this request, this DTC will be set. TROUBLESHOOTING HINTS (The most likely causes for these DTC are to set are:)
Current trouble
The CAN bus line is defective. Damaged connector(s) The G and yaw rate sensor is defective. The TCL/ASC-ECU is defective.
Past trouble Carry out diagnosis with particular emphasis on connector(s) or wiring harness
between the TCL/ASC-ECU and the G and yaw rate sensor. For diagnosis
procedures, refer to HOW TO COPE WITH INTERMITTENT MALFUNCTIONS
.
DIAGNOSIS Required Special Tools:
MB991958: Scan Tool (MUT-III Sub Assembly)
MB991824: Vehicle Communication Interface (V.C.I.) MB991827: MUT-III USB Cable MB991910: MUT-III Main Harness A
STEP 1. Using scan tool MB991958, diagnose the CAN bus line.
CAUTION: To prevent damage to scan tool MB991958,

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.
6. If defective, repair it. (Refer to TCL DIAGNOSIS

).
TCL SWITCH CHECK 1. Remove the TCL switch. (Refer to TCL SWITCH
).
2. Measure the resistance between terminal 1 and terminal 2 when the TCL
switch is pressed or released. If the values measured at the time correspond to
those in the table below, the resistance values are correct.

. CAUTION: The engine speed increases after the actuator
test because the actuator test continues for only
three seconds. Therefore, release the accelerator
pedal immediately.
