Pinpoint Test D: Unable To Program Keys

• Verify the keys present are the correct type for the vehicle.

Are the correct keys present? 

• Yes  : GO to D2 
• No  : The system cannot be tested without the correct keys. INFORM the customer the correct keys must be present to proceed with diagnosis of the system.

• Check for other valid programmed keys.

Is a valid programmed key present? 

• Yes  : GO to  D4
• No  : GO to D3 

• Verify the key is correctly placed in the backup starting location.

  REFER to: PASSIVE ANTI-THEFT SYSTEM (PATS) - SYSTEM OPERATION AND COMPONENT DESCRIPTION .

• Using a diagnostic scan tool, erase and program the new passive keys.

  REFER to: ANTI-THEFT SECURITY ACCESS .

Do the keys program? 

• Yes  : The vehicle is operating correctly. The concern was caused by an improperly placed passive key.
• No  : GO to  D6

• Ignition OFF.
• Disconnect BCM Fuse 32 (10A).
• Place the valid  programmed key in the backup starting location.

  REFER to: PASSIVE ANTI-THEFT SYSTEM (PATS) - COMPONENT LOCATION .

• Press the START/STOP button.

Does the ignition transition out of OFF? 

• Yes  : INSTALL the BCM fuse 32 (10A). REMOVE the valid key from the backup starting location. Place the suspect  in the backup starting location and PROGRAM the key again.

  REFER to: ANTI-THEFT SECURITY ACCESS .

  If the key does not program, DISCARD the suspect key and PROGRAM a new key.

• No  : INSTALL the BCM fuse 32 (10A). GO to D5 

• Verify the key is correctly placed in the backup starting location.

  REFER to: PASSIVE ANTI-THEFT SYSTEM (PATS) - SYSTEM OPERATION AND COMPONENT DESCRIPTION .

• Press the START/STOP button.

Does the ignition transition out of OFF? 

• Yes  : The vehicle is operating correctly. The concern was caused by an improperly placed passive key.
• No  : GO to D6 

• Disconnect PATS Center Antenna C3513  .
• Measure:

  Positive Lead	Measurement/Action	Negative Lead
  C3513, pin 1, component side		C3513, pin 2, component side

Is the resistance between 1 and 10 ohms? 

• Yes  : GO to D7 
• No  : INSTALL a new PATS center antenna,

  REFER to: PASSIVE ANTI-THEFT SYSTEM (PATS) CENTER ANTENNA .

• Disconnect BCM C2280G  .
• Measure:

  Positive Lead	Measurement/Action	Negative Lead
  C3513-1		Ground
  C3513-2		Ground

Is any voltage present? 

• Yes  : REPAIR the circuit in question.
• No  : GO to D8 

• Measure:

  Positive Lead	Measurement/Action	Negative Lead
  C3513-1		Ground
  C3513-2		Ground

Are the resistances greater than 10, 000 ohms? 

• Yes  : GO to D9 
• No  : REPAIR the circuit in question.

• Measure:

  Positive Lead	Measurement/Action	Negative Lead
  C3513-1		C2280G-40
  C3513-2		C2280G-27

Are the resistances less than 3 ohms? 

• Yes  : INSTALL a new PATS center antenna.

  REFER to: PASSIVE ANTI-THEFT SYSTEM (PATS) CENTER ANTENNA .

  TEST the system for normal operation. If the concern is still present, GO to D10 

• No  : REPAIR the circuit in question.

• Disconnect and inspect all of the BCM 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 BCM 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 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 BCM.

  REFER to: BODY CONTROL MODULE (BCM) .

• 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.
