measures more than 1 V): Go to Step 13.
STEP 5. Measure the resistance at TCL/ASC-ECU connector A-32.
1. Disconnect the connector A-32, and connect special tool ABS Check
Harness (MB991952) to the wiring harness-side connector.
2. Measure the resistance between the relevant signal and ground terminals
in the ABS sensor circuit and body ground. There should be no continuity.
DTC C1200 is set: Between signal terminal 30 and body ground, and
between ground terminal 21 and body ground DTC C1205 is set: Between signal terminal 22 and body ground, and
between ground terminal 31 and body ground DTC C1210 is set: Between signal terminal 8 and body ground, and
between ground terminal 9 and body ground DTC C1215 is set: Between signal terminal 6 and body ground, and between ground terminal 7 and body ground
NOTE: Do not connect special tool ABS Check Harness
(MB991952) to the TCL/ASC-ECU.

Q: Does continuity exist?
YES (Continuity exists between terminal 30 or terminal 21 and body
ground): Go to Step 7.
YES (Continuity exists between terminal 22 or terminal 31 and body
ground): Go to Step 9.
YES (Continuity exists between terminal 8 or terminal 9 and body
ground): Go to Step 11.
YES (Continuity exists between terminal 6 or terminal 7 and body
ground): Go to Step 13.
NO: Go to Step 6.
STEP 6. Measure the resistance at the TCL/ASC-ECU connector A-32.
1. Disconnect the connector A-32, and connect special tool ABS Check
Harness (MB991952) to the wiring harness-side connector.
2. Measure the resistance between the TCL/ASC-ECU connector terminals.
DTC C1200 is set: Between terminal 30 and terminal 21 DTC C1205 is set: Between terminal 22 and terminal 31 DTC C1210 is set: Between terminal 8 and terminal 9 DTC C1215 is set: Between terminal 6 and terminal 7
NOTE: Do not connect special tool ABS Check Harness
(MB991952) to the TCL/ASC-ECU.

Q: Is the harness wire between TCL/ASC-ECU connector A-32 (terminal
30, 21) and ABS sensor < front: RH > connector A-31 (terminal 1, 2)
damaged?
YES: Repair the wiring harness. Then go to Step 17.
NO: Go to Step 15.
STEP 9. Check TCL/ASC-ECU connector A-32 and ABS sensor < front:
LH > connector A-14 for loose, corroded or damaged terminals, or
terminals pushed back in the connector.

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 TCL/ASC electronic control unit
(TCL/ASC-ECU). The ABS hydraulic unit modulates the amount of braking force individually
applied to each wheel cylinder.
ABS DTC SET CONDITIONS The TCL/ASC-ECU monitors the signals from each ABS sensor while the vehicle
is being driven. If any faults below are found in these sensor signals, the ECU will
set the relevant diagnostic trouble code.
Missing sensor signal Sensor signal, which will not be created under normal operation Significant difference among the ABS sensor signals
TROUBLESHOOTING HINTS (The most likely causes for these DTCs are to set are:)
Current trouble
Malfunction of the ABS sensor or ABS rotor Damaged wiring harness or connector Malfunction of the hydraulic unit (integrated with TCL/ASC-ECU)
Past trouble
Carry out diagnosis with particular emphasis on connector(s) or wiring harness
in ABS sensor circuit. For diagnosis procedures, refer to "HOW TO USE TROUBLESHOOTING/INSPECTION SERVICE POINTS
.
DIAGNOSIS Required Special Tools:
MB991958: Scan Tool (MUT-III Sub Assembly)
MB991824: Vehicle Communication Interface (V.C.I.) MB991827: MUT-III USB Cable
