RESISTANCE AND CONTINUITY BETWEEN HARNESS-SIDE CONNECTOR TERMINALS 1. Disconnect the connector A-32, and connect special tool ABS Check Harness
(MB991952) to the wiring harness-side connector.
2. Measure the resistance and continuity between the terminals indicated in the
table below. NOTE: Do not measure terminal voltage for approximately
three seconds after the ignition switch is turned "ON."
The TCL/ASC-ECU performs the initial check during
that period.
NOTE: Do not connect special tool ABS Check Harness
(MB991952) to the TCL/ASC-ECU.

12. After inspection, disconnect scan tool MB991958 immediately after turning the
ignition switch to the "LOCK" (OFF) position.
IN THE EVENT OF A DISCHARGED BATTERY If the engine is started using a booster cable when the battery is completely flat, and
the vehicle is then driven without waiting for the battery to be recharged, the engine
may misfire and it may not be possible to drive the vehicle. This is because the ABS
consumes a large amount of current when carrying out its initial checks. If this
happens, recharge the battery fully.
WARNING:If the ABS is not operating, the vehicle will be
unstable during braking, Do not drive the vehicle
with the TCL/ASC-ECU connector disconnected or
with the TCL/ASC not operating for any other
reason.

CAUTION:
If DTC C1396 is set in the ABS/TCL-ECU < FWD >
or TCL/ASC-ECU < AWD >, always diagnose the
CAN main bus line. If there is any fault in the
CAN bus lines, an incorrect DTC may be set. Whenever the ABS/TCL-ECU < FWD > or

2. Turn the ignition switch to the "ON" position.
3. Use scan tool MB991958 to read the TCL diagnostic trouble codes.
4. Turn the ignition switch to the "LOCK" (OFF) position.
5. Disconnect scan tool MB991958.
Q: Is DTC C1396 set?
YES: Replace the hydraulic unit (integrated with ABS/TCL-ECU < FWD > or
TCL/ASC-ECU < AWD >). (Refer to HYDRAULIC UNIT
). Then go to Step
4.
NO: It can be assumed that this malfunction is intermittent. (Refer to HOW
TO COPE WITH INTERMITTENT MALFUNCTIONS
).
STEP 4. Using scan tool MB991958, read the diagnostic trouble code.
1. Connect scan tool MB991958 to the data link connector. (Refer
toTRACTION CONTROL SYSTEM (TCL) DIAGNOSIS
). 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.

Malfunction of the A/T system. Malfunction of the ABS/TCL-ECU < FWD > or TCL/ASC-ECU < AWD >.
DIAGNOSIS
CAUTION:
If DTC C1397 is set in the ABS/TCL-ECU < FWD >
or TCL/ASC-ECU < AWD >, always diagnose the
CAN main bus line. If there is any fault in the
CAN bus lines, an incorrect DTC may be set. Whenever the ABS/TCL-ECU < FWD > or
TCL/ASC-ECU < AWD > is replaced, ensure that
the communication circuit is normal. The A/T system-related DTC may be set when
DTC C1397 is set. Diagnose the A/T system first
when the A/T system-related DTC is set.
