Pinpoint Test B: No Power In Acc
WARNING: This page is about a different car, the 2013 Ford F-550 Super Duty, 2013 Ford F-450 Super Duty, 2013 Ford F-350 Super Duty, and 2013 Ford F-250 Super Duty. 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 IGNITION SWITCH
- Carry out the IGNITION SWITCH Component Test. Refer to appropriate "OEM Wiring Diagrams Component Testing" article for component testing.
- Is the ignition switch OK?
- Yes : GO to B2.
- No : INSTALL a new ignition switch. REFER to Ignition Switch . TEST the system for normal operation.
- B2 CHECK VEHICLE EQUIPMENT NOTE: The CDIM is not installed on vehicles equipped with a gasoline engine and is optional for vehicles equipped with a diesel engine.
- Verify the vehicle is equipped with a CDIM.
- Is the vehicle equipped with a CDIM?
- Yes : GO to B5.
- No : GO to B3.
- B3 CHECK THE RUN/ACC CIRCUIT FOR AN OPEN
- Disconnect: BCM C2280B.
- Disconnect: BCM C2280A.
- Ignition In ACC.
- Measure the voltage between ground and:
- BCM C2280B-35, circuit CDC33 (VT/GN), harness side.
- BCM C2280A-10, circuit CDC33 (VT/GN), harness side.
- Is the voltage greater than 10 volts?
- Yes : GO to B4.
- No : REPAIR circuit CDC33 (VT/GN) for an open. TEST the system for normal operation.
- B4 CHECK THE ELECTRICAL BCM CONNECTORS
- Check the BCM electrical connectors C2280A and C2280B for:
- corrosion
- damaged pins
- pushed-out pins
- Repair any identified concerns.
- Connect the BCM connectors and make sure they are seated correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
- Yes : INSTALL a new BCM. REFER to MULTIFUNCTION ELECTRONIC MODULES . 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. TEST the system for normal operation.
- Check the BCM electrical connectors C2280A and C2280B for:
- B5 REVIEW THE CDIM DTCs
- Review the CDIM DTCs retrieved during Inspection and Verification.
- Are any CDIM DTCs present?
- Yes
: For DTC B1359, GO to PINPOINT TEST F .
For all other CDIM DTCs, GO to the CDIM DTC Chart .
- No : GO to B6.
- B6 CHECK THE RUN/ACC CIRCUIT FOR AN OPEN
- Disconnect: BCM C2280A.
- Ignition In ACC.
- Measure the voltage between BCM C2280A-10, circuit CDC33 (VT/GN), harness side and ground.
- Is the voltage greater than 10 volts?
- Yes : GO to B7.
- No : REPAIR the circuit CDC33 (VT/GN) for an open. TEST the system for normal operation.
- B7 CHECK THE RUN/ACC CIRCUIT FOR AN OPEN
- Ignition OFF.
- Disconnect: BCM C2280B.
- Ignition In ACC.
- Measure the voltage between BCM C2280B-35, circuit CDC63 (YE/OG), harness side and ground.
- Is the voltage greater than 10 volts?
- Yes : INSTALL a new BCM. REFER to MULTIFUNCTION ELECTRONIC MODULES . TEST the system for normal operation.
- No : GO to B8.
- B8 ISOLATE THE CDIM
- Disconnect: CDIM C2500.
- Connect a fused jumper wire between:
- CDIM C2500-1, CDC33 (VT/GN), harness side and CDIM C2500-8, CDC63 (YE/OG), harness side.
- Ignition In ACC.
- Measure the voltage between BCM C2280B-35, circuit CDC63 (YE/OG), harness side and ground.
- Is the voltage greater than 10 volts?
- Yes : GO to B9.
- No : REPAIR circuit CDC33 (VT/GN) or CDC63 (YE/OG). TEST the system for normal operation.
- B9 CHECK THE CDIM GROUND CIRCUIT FOR AN OPEN
- Ignition OFF.
- Measure the resistance between CDIM C2500-11, circuit GD184 (BK/GY), harness side and ground.
- Is the resistance less than 5 ohms?
- Yes : GO to B10.
- No : REPAIR circuit CD184 (BK/GY). TEST the system for normal operation.
- B10 CHECK CDIM ELECTRICAL CONNECTOR
- Check the CDIM electrical connector C2500 for:
- corrosion
- damaged pins
- pushed-out pins
- Repair any identified concerns.
- Connect the CDIM connector and make sure it seats correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
- Yes : INSTALL a new CDIM. REFER to Circuit Deactivation Ignition Module (CDIM) . 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. TEST the system for normal operation.
- Check the CDIM electrical connector C2500 for:
