CIRCUIT OPERATION
The TCL/ASC-ECU contains the power supply circuit (terminal 11) for the
solenoid valve. The solenoid valve is energized by the valve relay, which i
incorporated in the TCL/ASC-ECU. The valve relay, which is incorporated in the TCL/ASC-ECU, is always
energizing the solenoid valve unless the initial check is in progress when the
ignition switch is turned on. The TCL/ASC-ECU activates the solenoid valve by turning on its driving
transistor.
TCL/ASC DTC SET CONDITIONS These diagnostic trouble codes will be set under the cases below.
The solenoid valve is not energized even after the TCL/ASC-ECU has turned
on the driving transistor (Open circuit is present in the power supply circuit to
the TCL/ASC-ECU solenoid valve, or the valve relay has failed). The solenoid valve is not energized even after the TCL/ASC-ECU has turned
on the driving transistor (Open circuit is present in the solenoid valve circuit
inside the TCL/ASC-ECU, or the valve relay has failed). After the TCL/ASC-ECU has turned off the driving transistor, the solenoid
valve still remains energized (short in the solenoid valve circuit). When a solenoid valve failure is detected

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 11) to the TCL/ASC-ECU solenoid valve
or ground circuit (terminal 12). For diagnosis procedures, refer to HOW TO COPE WITH INTERMITTENT MALFUNCTIONS
).
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
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.
