wiring harness between G and yaw rate sensor connector C-36 terminals 4
and the body ground. Then go to Step 7.
NO: Repair or replace the damaged component(s). Then go to Step 7.
STEP 5. Check the battery.
Check the battery (Refer toBATTERY TEST
).
Q: Is the battery in good condition?
YES: Go to Step 6.
NO: Charge or replace the battery. Then go to Step 7.
STEP 6. Check the charging system.
Check the charging system (Refer to GENERATORS & REGULATORS
).
Q: Is the charging system in good condition?
YES: Replace the G and yaw rate sensor (Refer to G AND YAW RATE
SENSOR
). Then go to Step 7.
NO: Repair or replace the charging system component(s). Then go to Step
7.
STEP 7. Using scan tool MB991958, read the TCL/ASC diagnostic trouble
code.
1. Connect scan tool MB991958 to the data link connec
tor. CAUTION: To prevent damage to scan tool always turn the
ignition switch to "LOCK" (OFF) position before
connecting or disconnecting scan tool.

.
2. Turn the ignition switch to the "ON" position.
3. Read the TCL/ASC diagnostic trouble code.
Q: Is the DTC U1105 (current trouble) set?
YES: Diagnose the TCL/ASC by referring to DTC U1105: YR/G CAN
TIMEOUT/NOT EQUIPPED
.
NO: The procedure is complete.
INSPECTION PROCEDURE 11: TCL/ASC System dose not Operate. COMMENT The fall-safe function is probably canceling TCL/ASC system. In this case, scan
tool MB991958 can be used to Retest each system by checking the diagnostic
trouble codes. TROUBLESHOOTING HINTS (The most likely causes for this case:)
Malfunction of the CAN bus line. Malfunction of the TCL/ASC-ECU.
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. Hydraulic unit check
Refer to POINTS IN WAVEFORM MEASUREMENT
.
Q: Is the hydraulic unit normal?

2004 BRAKES Traction Control, Active Skid Control System - Endeavor

YES: Go to Step 2.
NO: Connect the brake pipes correctly, repair the external brake lines, or
replace the hydraulic unit.
STEP 2. Verify that the condition described by the customer exists.
Q: Can any faults be found with the brake operation?
YES: Check the brake system related components except the ASC system.
NO: The procedure is complete.
DATA LIST REFERENCE TABLE The following items can be read by the scan tool from the TCL/ASC-ECU input
