CIRCUIT OPERATION
The TCL/ASC-ECU contains the power supply circuit (terminal 33) for the
pump motor. The pump motor is energized by the motor relay, which is
incorporated in the TCL/ASC-ECU. The motor relay, which is incorporated in the TCL/ASC-ECU, is always off
unless the motor solenoid valve check is activated when the vehicle is started. The TCL/ASC-ECU activates the pump motor by turning on the ECU built-in
motor relay when the ABS is working.
TCL/ASC DTC SET CONDITIONS These diagnostic trouble codes will be set under the cases below. DTC C1266: MOTOR SYSTEM (SEIZURE)
If the TCL/ASC-ECU determines that the pump motor is not running smoothly
(i.e. motor seizure) after the motor relay is turned off, this DTC will be set.
DTC C1273: MOTOR RELAY PROBLEM (STUCK OFF)
If the TCL/ASC-ECU determines that the motor is not running after the motor
relay is turned on, the ECU determines that the motor relay is stuck off, and
sets this DTC.
DTC C1274: MOTOR RELAY PROBLEM (STUCK ON)
If the TCL/ASC-ECU determines that the motor is running after the motor
relay is turned off, the ECU determines that the motor relay is stuck on, and
sets this DTC.
TROUBLESHOOTING HINTS (The most likely causes for these DTCs are to set are:)
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.

Current trouble
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 the power supply circuit (terminal 33) to the TCL/ASC-ECU motor or
ground circuit (terminal 34). 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
MB991952: 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.

YES: Go to Step 3.
NO: Repair the CAN bus line (Refer toDIAGNOSTIC 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.
