DTC C1607: Trouble in ABS-ECU ABS DTC SET CONDITIONS The ABS-ECU always monitors itself while the system is working. If the ECU
detects any faults, it will set this DTC. TROUBLESHOOTING HINTS (THE MOST LIKELY CAUSES FOR THESE DTCS ARE TO SET ARE:)
Malfunction of the hydraulic unit (integrated with ABS-ECU)
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
STEP 1. Using scan tool MB991958, diagnose the CAN bus line. 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.
CAUTION: Whenever the ECU is replaced, ensure that the CAN
bus lines are normal.
