PINPOINT TEST B: DTCs C1095 AND C1096
WARNING: This page is about a different car, the 2010 Lincoln MKX and 2010 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Use the Flex Probe Kit for all test connections to prevent damage to the wiring terminals. Do not use standard multi-meter probes.
- B1 CHECK THE ABS PUMP MOTOR
- Ignition ON.
- Is the ABS pump motor running all the time?
- Yes: INSTALL a new ABS module and HCU . REFER to ANTI-LOCK BRAKE SYSTEM (ABS) MODULE and HYDRAULIC CONTROL UNIT (HCU) . CLEAR the DTCs. REPEAT the self-test.
- No: GO to B2 .
- B2 CHECK FOR ABS MODULE DTCs
- Connect the scan tool.
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: Self Test - Clear All CMDTCs .
- Enter the following diagnostic mode on the scan tool: Self Test - ABS Module.
- Retrieve and record all ABS module DTCs.
- Does DTC C1095 and/or C1096 return?
- Yes:
If DTC C1095 is retrieved, GO to B4.
If DTC C1096 is retrieved, INSTALL a new ABS module. REFER to ANTI-LOCK BRAKE SYSTEM (ABS) MODULE . CLEAR the DTCs. CARRY OUT the self-test with the brake pedal not applied.
If DTC C1096 returns, INSTALL a new HCU . REFER to HYDRAULIC CONTROL UNIT (HCU) . CLEAR the DTCs. CARRY OUT the self-test with the brake pedal not applied.
- No: GO to B3 .
- B3 CHECK FOR RETURNING ABS MODULE DTCs
- Test drive the vehicle at speeds greater than 32 km/h (20 mph) and carry out at least one ABS stop.
- Connect the scan tool.
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: Self Test - ABS Module.
- Retrieve and record the ABS module DTCs.
- Are any DTCs present?
- Yes:
If DTC C1096 is retrieved, GO to B6.
If DTC C1095 is retrieved, INSTALL a new HCU . REFER to HYDRAULIC CONTROL UNIT (HCU) . CLEAR the DTCs. REPEAT the self-test.
For all other ABS module DTCs, GO to the ABS MODULE DTC CHART .
- No: The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. CARRY OUT the self-test with the brake pedal not applied.
- B4 CHECK THE ABS MODULE PUMP MOTOR B+ CIRCUIT FOR AN OPEN NOTE: The battery and battery tray need to be removed to access the ABS module connector.
- Ignition OFF.
- Disconnect: ABS Module C135.
- Measure the resistance between ABS module C135-1, circuit SBB15 (WH/RD), harness side and BJB fuse 15 (40A), circuit SBB15 (WH/RD), output side.
- Is the resistance less than 5 ohms?
- Yes: GO to B5 .
- No: VERIFY BJB fuse 15 (40A) is OK. If OK, REPAIR circuit SBB15 (WH/RD). If not OK, REFER to the SYSTEM WIRING DIAGRAMS for Edge or SYSTEM WIRING DIAGRAMS for MKX to identify the possible causes of the circuit short. CLEAR the DTCs. REPEAT the self-test.
- B5 CHECK THE ABS MODULE GROUND CIRCUITS FOR AN OPEN
- Ignition OFF.
- Measure the resistance between ABS module C135-13, circuit GD121 (BK/YE), harness side and ground.
- Is the resistance less than 5 ohms?
- Yes: INSTALL a new HCU . REFER to HYDRAULIC CONTROL UNIT (HCU) . CLEAR the DTCs. REPEAT the self-test. If DTC C1095 is retrieved, GO to B6 .
- No: REPAIR circuit GD121 (BK/YE). CLEAR the DTCs. REPEAT the self-test.
- B6 CHECK FOR CORRECT ABS MODULE OPERATION
- Disconnect: ABS Module C135.
- Check the connector for:
- corrosion.
- pushed-out pins.
- spread terminals.
- Connect: ABS C135.
- Make sure the ABS connector seats correctly, then operate the system and verify the concern is still present.
- Is the concern still present?
- Yes: INSTALL a new ABS module. REFER to ANTI-LOCK BRAKE SYSTEM (ABS) MODULE . TEST the system for normal operation.
- No: The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test.
