DTC Fault Trigger Conditions
DTC Description Fault Trigger Condition BCM C113A:11 Wakeup Control: Circuit Short To Ground Sets when the BCM detects a short to ground from the wakeup control output circuit. BCM C113A:15 Wakeup Control: Circuit Short To Battery Or Open Sets when the BCM detects an open short to voltage from the wakeup control output circuit. Possible Sources
- Wiring, terminals or connectors
- PATS transceiver
- BCM
- PCM
- NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
- F1 REVIEW THE BCM (BODY CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE SELF-TEST
- Review the Diagnostic Trouble Codes (DTCs) from the BCM self-test.
Is DTC C113A:11 present?
Yes GO to F2 No GO to F5 - F2 ISOLATE THE PCM (POWERTRAIN CONTROL MODULE) AS THE CAUSE FOR A SHORT TO GROUND
- Ignition OFF.
- Disconnect PCM B-Connector.

- Disconnect PATS Transceiver C252.
- Ignition ON.
- Using a diagnostic scan tool, carry out the BCM self-test.
Is DTC C113A:11 still present?
Yes GO to F4 No INSTALL a new PATS transceiver. - F4 CHECK THE WAKEUP CONTROL OUTPUT CIRCUITS FOR A SHORT TO GROUND
- Ignition OFF.
- Disconnect BCM C2280D.
- Disconnect BCM C2280E.
- Measure:
Positive Lead Measurement / Action Negative Lead C2280D-16 Ground Positive Lead Measurement / Action Negative Lead C2280E-10 Ground
Are the resistances greater than 10, 000 ohms?
Yes GO to F11 No REPAIR the circuit in question. - F5 CHECK THE WAKEUP CONTROL CIRCUIT FOR AN OPEN OR SHORT TO VOLTAGE
- Attempt to start the vehicle.
Does the vehicle start?
Yes GO to F7 No GO to F6 - F6 CHECK THE WAKEUP CONTROL CIRCUIT FOR AN OPEN
- Ignition OFF.
- Disconnect PATS Transceiver C252.
- Disconnect BCM C2280D.
Is the resistance less than 3 ohms?
Yes GO to F11 No REPAIR the circuit. - F7 ISOLATE THE PCM (POWERTRAIN CONTROL MODULE) AS THE CAUSE FOR A SHORT TO VOLTAGE
- Ignition ON.
- Using a diagnostic scan tool, clear the BCM Diagnostic Trouble Codes (DTCs).
- Ignition OFF.
- Disconnect PCM B-Connector.
- Ignition ON.
- Using a diagnostic scan tool, carry out the BCM self-test.
Is DTC C113A:15 still present?
Yes GO to F8 No GO to F10 - F8 CHECK THE PCM (POWERTRAIN CONTROL MODULE) WAKEUP CONTROL CIRCUIT AS THE CAUSE FOR A SHORT TO VOLTAGE
- Ignition OFF.
- Disconnect BCM C2280E.
- Ignition ON.
- Measure:
Positive Lead Measurement / Action Negative Lead C2280E-10 Ground
Is any voltage present?
Yes REPAIR the circuit. No GO to F9 - F9 CHECK THE PATS (PASSIVE ANTI-THEFT SYSTEM) TRANSCEIVER WAKEUP CONTROL CIRCUIT FOR A SHORT TO VOLTAGE
- Disconnect BCM C2280D.
- Measure:
Positive Lead Measurement / Action Negative Lead C2280E-16 Ground
Is any voltage present?
Yes REPAIR the circuit. No GO to F11 - F10 CHECK FOR CORRECT PCM (POWERTRAIN CONTROL MODULE) OPERATION
- Ignition OFF.
- Disconnect and inspect all of the PCM connectors.
- Repair:
- corrosion (install new connectors or terminals, clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary
- Reconnect all the PCM connectors and 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 PCM GUIDED ROUTINE TESTING 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. - F11 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION
