CIRCUIT OPERATION
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
).

A toothed ABS rotor generates a voltage pulse as it moves across the pickup
field of each ABS sensor. 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 TCL/ASC electronic control unit
(TCL/ASC-ECU). The ABS hydraulic unit modulates the amount of braking force individually
applied to each wheel cylinder.
TCL/ASC DTC SET CONDITIONS The TCL/ASC-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 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 MB991910: MUT-III Main Harness A

.
2. Start the engine.
3. Set scan tool MB991958 to the data reading mode, and check the data list
items by driving the vehicle.
Item 01 (DTC C1200 is set): Front right ABS sensor Item 02 (DTC C1205 is set): Front left ABS sensor Item 03 (DTC C1210 is set): Rear right ABS sensor Item 04 (DTC C1215 is set): Rear left ABS sensor
4. Turn the ignition switch to the "LOCK" (OFF) position.
Q: Does the speedometer indication match the scan tool indication?
YES: It can be assumed that this malfunction is intermittent.
Refer to HOW TO COPE WITH INTERMITTENT
MALFUNCTIONS
.
NO: Go to Step 4.
STEP 4. Measure the voltage 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. Turn the ignition switch to the "ON" position.
3. Measure the voltage between the relevant signal and ground terminals in
the ABS sensor circuit and body ground. It should be less than 1V.
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 si
gnal terminal 8 and bo
dy ground, and
NOTE: Do not connect special tool ABS Check Harness
(MB991952) to the TCL/ASC-ECU.

Q: Does the voltage measure 1 V or less?
YES: Go to Step 5.
NO (When the voltage between terminal 30 or 21 - and body ground
measures more than 1 V): Go to Step 7.
NO (When the voltage between terminal 22 or 31 - and body ground
measures more than 1 V): Go to Step 9
NO (When the voltage between terminal 8 or 9 - and body ground
measures more than 1 V): Go to Step 11.
NO (When the voltage between terminal 6 or 7 - and body ground
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.

Standard Value: 1.24 - 1.64 koh
m
Q: Is the resistance between terminals 30 and 21, 22 and 31, 8 and 9, or 6
and 7 within the standard value?
YES (When resistances between all terminals are within the standard
value): Go to Step 16.
NO (When resistance between terminal 30 and 21 is not within the
standard value): Go to Step 7.
NO (When resistance between terminals 22 and 31 is not within the
standard value): Go to Step 9.
NO (When resistance between terminals 8 and 9 is not within the
standard value): Go to Step 11.
NO (When resistance between terminals 6 and 7 is not within the
standard value): Go to Step 13.
STEP 7. Check TCL/ASC-ECU connector A-32 and ABS sensor < front:
RH > connector A-31 for loose, corroded or damaged terminals, or
terminals pushed back in the connector.

Q: Are TCL/ASC-ECU connector A-32 and ABS sensor < front: RH >
connector A-31 damaged?
YES: Repair or replace the damaged component(s). Then go to Step 17.
NO: Go to Step 8.
STEP 8. Check the harness wires between TCL/ASC-ECU connector A-32
(terminal 30, 21) and ABS sensor < front: RH > connector A-31 (terminal
2, 1).
