A5 CHECK FOR CORRECT PCM (POWERTRAIN CONTROL MODULE) OPERATION

Ignition OFF. Disconnect and inspect all the PCM connectors and related in-line connectors. Repair:

corrosion (install new connector or terminals - clean module pins) damaged or bent pins - install new terminals/pins pushed-out pins - install new pins as necessary

Reconnect the PCM connectors and related in-line connectors. Make sure they seat and latch correctly. Operate the system and determine if the concern is still present.

Is the concern still present?

Yes	CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new PCM. For 2.3L, REFER to: Powertrain Control Module (PCM) (303-14A Electronic Engine Controls - 2.3L EcoBoost (231kW/314PS), Removal and Installation). For 3.7L, REFER to: Powertrain Control Module (PCM) (303-14B Electronic Engine Controls - 3.7L Duratec (227kW/301PS), Removal and Installation). For 5.0L, REFER to: Powertrain Control Module (PCM) (303-14C Electronic Engine Controls - 5.0L 32V Ti-VCT/5.0L Ti-VCT V8 (308kW/418PS), Removal and Installation). For 5.2L, REFER to: Powertrain Control Module (PCM) (303-14D Electronic Engine Controls - 5.2L 32V Ti-VCT, Removal and Installation).
No	The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.

The Anti-Lock Brake System (ABS) Module Does Not Respond To The Diagnostic Scan Tool

Refer to Wiring Diagrams Cell 14 for schematic and connector information.

Refer to Wiring Diagrams Cell 42 for schematic and connector information.

Normal Operation and Fault Conditions

The ABS module communicates with the diagnostic scan tool through the HS-CAN2.

Possible Sources

Fuse Wiring, terminals and connectors ABS module

Visual Inspection and Diagnostic Pre-checks

Verify BJB fuses 5 (50A), 28 (30A) and 62 (5A) are OK.

PINPOINT TEST B : THE ANTI-LOCK BRAKE SYSTEM (ABS) MODULE DOES NOT RESPOND TO THE

DIAGNOSTIC SCAN TOOL

B1 CHECK THE ABS (ANTI-LOCK BRAKE SYSTEM) MODULE VOLTAGE SUPPLY CIRCUITS FOR AN OPEN

Ignition OFF. Disconnect: ABS module C135 Ignition ON.
