CAUTION: If there is any problem in the CAN bus lines, an
incorrect diagnostic trouble code may be set. Prior to
this diagnosis, diagnose the CAN bus lines.

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 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 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 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 (Refer to HOW TO USE TROUBLESHOOTING/ INSPECTION SERVIC
).
PAST TROUBLE For diagnosis procedures, refer to "HOW TO TREAT PAST TROUBLE
" (Refer
to HOW TO USE TROUBLESHOOTING/ INSPECTION SERVIC
).
DIAGNOSIS

Page 59 of 3870
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 DIAGNOSTIC TROUBLE
CODE DIAGNOSIS
or DIAGNOSIS < VEHICLES WITHOUT
ADVANCED AIR BAG
). 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.
3. Turn the ignition switch to the "LOCK" (OFF) position.
4. Turn the ignition switch to the "ON" position.
5. Check if the DTC is set. 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.

6. Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC C1201, C1206, C1211 and C1216 set?
YES: Go to Step 3.
NO: The procedure is complete.
STEP 3. Using scan tool MB991958, read the diagnostic trouble code.
Use scan tool MB991958 to check whether DTC codes C1200, C1205, C1210
and C1215 have been set simultaneously.
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.
