CIRCUIT OPERATION
The ABS-ECU power is supplied to the ABS-ECU
(terminal 9) from the ignition switch (IG2) through the
fuse number 4 in the junction block and through the
joint connector number 1.
.
ABS DTC SET CONDITIONS
Output is provided when ABS-ECU power supply
voltage drops below or rises above the normal value.
Output is not provided if power supply voltage
returns to normal voltage.
.
TROUBLESHOOTING HINTS
The most likely causes for DTC is to set are:
• Damaged wiring harness and connector
• Malfunction of hydraulic unit (integrated with
ABS-ECU)
.
DIAGNOSIS

• MB991958: Scan Tool (MUT-III Sub Assembly)
• MB991824: Vehicle Communication Interface (V.C.I.)
• MB991827: MUT-III USB Cable
• MB991911: MUT-III Main Harness B
