DTC Fault Trigger Conditions

DTC Description Fault Trigger Condition
BCM B1277:11 Reverse Lamp: Circuit Short To Ground A continuous memory and on-demand DTC that sets when the BCM detects a short to ground from the reversing lamps output circuit.
BCM B1277:15 Reverse Lamp: Circuit Short To Battery Or Open A continuous memory and on-demand DTC that sets when the BCM detects an open or short to voltage from the reversing lamps output circuit.

Possible Sources

  • Wiring, terminals or connectors
  • Gear range concern
  • BCM
A1 CHECK THE PCM (POWERTRAIN CONTROL MODULE) TRANSMISSION RANGE PID (PARAMETER IDENTIFICATION)
  • Apply the parking brake.
  • Ignition ON.
  • Access the  PCM  and monitor the  TR_CORRECTED  PID

  • Place the gear selector in each gear.

Does the PID indicate the correct value in each gear selection?
Yes If both reverse lamps are inoperative, GO to A2
If both reverse lamps are always on, GO to A5
No DIAGNOSE the transmission range concern.
REFER to: Diagnosis By Symptom (307-01A Automatic Transmission - 10-Speed Automatic Transmission – 10R60, Diagnosis and Testing).

A2 CHECK THE REVERSING LAMP VOLTAGE CIRCUIT FOR A SHORT TO GROUND
  • Place the gear selector in PARK (P).
  • Ignition OFF.
  • Disconnect: Inline (reversing lamp assembly) C424M.
  • Disconnect: BCM C2280C.
  • Measure:
    Click to display connectors
    Positive Lead Measurement / Action Negative Lead
      C2280C-11   Ground

Is the resistance greater than 10,000 ohms?
Yes GO to A3
No REPAIR the circuit in question. After the repair:
If no Diagnostic Trouble Codes (DTCs) are present, TEST the system for normal operation.
If DTC U1000:00 is present, CLEAR the Diagnostic Trouble Codes (DTCs) and REPEAT the self-test (required to enable the lamp output driver if DTC U1000:00 is present).
If DTC U3000:49 is present, INSTALL a new BCM.
REFER to: Body Control Module (BCM) (419-10 Multifunction Electronic Modules, Removal and Installation).

A3 CHECK THE REVERSING OUTPUT CIRCUIT FOR A SHORT TO GROUND
  • Place the gear selector in PARK (P).
  • Ignition OFF.
  • Disconnect: BCM C2280G.
  • Disconnect: Auto-Dimming Interior Mirror C911.
  • Disconnect: BCMC C1035B (if equipped with towing package).
  • Measure:
    Click to display connectors
    Positive Lead Measurement / Action Negative Lead
      C2280G-19   Ground

Is the resistance greater than 10,000 ohms?
Yes GO to A4
No REPAIR the circuit in question. After the repair:
If no Diagnostic Trouble Codes (DTCs) are present, TEST the system for normal operation.
If DTC U1000:00 is present, CLEAR the Diagnostic Trouble Codes (DTCs) and REPEAT the self-test (required to enable the lamp output driver if DTC U1000:00 is present).
If DTC U3000:49 is present, INSTALL a new BCM.
REFER to: Body Control Module (BCM) (419-10 Multifunction Electronic Modules, Removal and Installation).

A4 CHECK THE REVERSING LAMP VOLTAGE CIRCUIT FOR AN OPEN
  • Measure:
    Click to display connectors
    Positive Lead Measurement / Action Negative Lead
      C424M-2   C2280C-11

Is the resistance less than 3 ohms?
Yes GO to A7
No REPAIR the circuit in question.

A5 CHECK THE REVERSING LAMP VOLTAGE SUPPLY CIRCUIT FOR A SHORT TO VOLTAGE
  • Ignition OFF.
  • Disconnect: BCM C2280C.
  • Ignition ON.

Are the reverse lamps still on?
Yes REPAIR the circuit.
No GO to A6

A6 CHECK THE REVERSING OUTPUT SUPPLY CIRCUIT FOR A SHORT TO VOLTAGE
  • Ignition OFF.
  • Connect: BCM C2280C.
  • Disconnect: BCM C2280G.
  • Disconnect: Auto-Dimming Interior Mirror C9012.
  • Disconnect: BCMC C1035B (if equipped with towing package).
  • Ignition ON.
  • Measure:
    Click to display connectors
    Positive Lead Measurement / Action Negative Lead
      C2280G-19   Ground

Is any voltage present?
Yes REPAIR the circuit.
No GO to A7

A7 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION
  • Disconnect and inspect all BCM 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 BCM 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 service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern,
REFER to: Body Control Module (BCM) (419-10 Multifunction Electronic Modules, 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.
