6. Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC U1073 set?
YES: Go to Step 1 .
NO: The procedure is complete.
SYMPTOM CHART NOTE: For vehicle with TCL/ASC, refer to SYMTOM CHART
.
CAUTION: During diagnosis, a DTC code associated with other
system may be set when the ignition switch is turned
on with connector(s) disconnected. On completion,
confirm all systems for DTC code(s). If DTC code(s)
are set, erase them all.
NOTE: If steering movements are made when driving at high
speed, or when driving on road surfaces with low frictional
resistance, or when passing over bumps, the ABS may
operate although sudden braking is not being applied.
Because of this, when getting information from the
customer, check if the problem occurred while driving
under such conditions as these.
NOTE: During ABS operation, the brake pedal may vibrate a little
or may not be able to be pressed. Such conditions are due
to intermittent changes in hydraulic pressure inside the
brake line to prevent the wheels from locking. This is
normal.

TECHNICAL DESCRIPTION (COMMENT) If the scan tool (MUT-III Sub Assembly) can not communicate with the ABS
system, the CAN bus lines may be defective. If the ABS system does not work, the
ABS-ECU or its power supply circuit may be defective. TROUBLESHOOTING HINTS (THE MOST LIKELY CAUSES FOR THIS CASE:)
Damaged wiring harness or connector Malfunction of the hydraulic unit (Integrated with ABS-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. Using scan tool MB991958, diagnose the CAN bus line.
CAUTION: To prevent damage to scan tool MB991958,
always turn the ignition switch to the
"LOCK" (OFF) position before connecting or
