.
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.

CIRCUIT OPERATION
A toothed ABS rotor generates a voltage pulse as it moves across the pickup
field of each ABS sensor.
CAUTION: If there is any problem in the CAN bus lines, an
incorrect diagnostic trouble code may be set.
Diagnose the CAN bus lines before the DTC (Refer to
DIAGNOSTIC TROUBLE CODE DIAGNOSIS
).

The amount of voltage generated at each wheel is determined by the clearance
between the ABS rotor teeth and the ABS sensor, and by the speed of rotation. Sends alternating current signals at frequencies which are proportional to the
rotation speeds of each wheel to the ABS electronic control unit (ABS-ECU). The ABS hydraulic unit modulates the amount of braking force individually
applied to each wheel cylinder.
ABS DTC SET CONDITIONS The ABS-ECU monitors voltage fluctuation in each ABS sensor circuit. If the ECU
detects short or open circuit in the circuit, it will set a diagnostic trouble code. TROUBLESHOOTING HINTS (THE MOST LIKELY CAUSES FOR THESE DTCS ARE TO SET ARE:)
Current trouble
Malfunction of the ABS sensor Damaged wiring harness or connector Malfunction of the hydraulic unit (integrated with ABS-ECU)
Past trouble
Carry out diagnosis with particular emphasis o connector(s) or wiring harness
in ABS sensor circuit. For diagnosis procedures, refer to HOW TO USE TROUBLESHOOTING/ INSPECTION SERVIC
).
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
MB991970: ABS Check Harness
STEP 1. Using scan tool MB991958, diagnose the CAN bus line.

1. Connect scan tool MB991958 to the data link connec
tor. CAUTION: To prevent damage to scan tool MB991958,
always turn the ignition switch to the
"LOCK" (OFF) position before connecting or
disconnecting scan tool MB991958.

2. Turn the ignition switch to the "ON" position.
3. Diagnose the CAN bus line.
4. Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the CAN bus line found to be normal?
YES: Go to Step 3
NO: Repair the CAN bus line (Refer to TCL/ASC DIAGNOSIS
, ). Then
go to Step 2.
STEP 2. Recheck for diagnostic trouble code.
1. Turn the ignition switch to the "ON" position.
2. Erase the DTC. CAUTION: To prevent damage to scan tool MB991958,
always turn the ignition switch to the
"LOCK" (OFF) position before connecting or
disconnecting scan tool MB991958.
