CIRCUIT OPERATION
The TCL/ASC-ECU is energized by the ignition switch (IG2) through multi-
purpose fuse 13 and the TCL/ASC-ECU terminal 32. If the power supply to the TCL/ASC-ECU has failed, scan tool MB991958 will
not be able to communicate with it.
TROUBLESHOOTING HINTS (The most likely causes for this case:)
Damaged wiring harness or connector Defective battery Charging system failed Malfunction of the hydraulic unit (integrated with TCL/ASC-ECU)

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. 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 terminal 32 and ground. It should measure
approximately 12 volts (battery positive voltage). NOTE: Do not connect special tool ABS Check Harness
(MB991952) to the TCL/ASC-ECU.
