B259A
B259A-00-Front Left Door Handle Sense
For a complete wiring diagram, refer to.
• When Monitored: During the Passive Entry or Keyless Go event.
• Set Condition: During the Passive Entry procedure and the FOBIK outside the car and within 6 feet from the handle, the module looks at the door handle circuits. If the sense or return circuits are open or shorted, for over two seconds, this code will set.
Test Step 1 - TEST FOR INTERMITTENT CONDITION
• Using the FOBIK, turn the ignition on.
• Using the scan tool, record and erase the DTCs.
• With the scan tool, select: PEM, More Options and System Tests.
• Perform the PEM Door Handle Verification Tests.
• With the scan tool, read the Active DTCs.
Does the scan tool display: B259A-00-FRONT LEFT DOOR HANDLE SENSE as active?
Yes
• Go to Test Step 2
No
• Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals and correct pin tension.
• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior
Test Step 2 - (P125) LEFT FRONT PASSIVE ENTRY HANDLE SWITCH SENSE CIRCUIT OPEN
• Turn the ignition off.
• Disconnect the Left Front Exterior Door Handle Switch harness connector.
• Turn the ignition on.
• Measure the voltage between the (P125) Left Front Passive Entry Handle Switch Sense circuit and ground.
Is the voltage above 8.0 Volts?
Yes
• Go to Test Step 3
No
• Go to Test Step 5
Test Step 3 - (P124) LEFT FRONT PASSIVE HANDLE SWITCH RETURN CIRCUIT OPEN
• Turn the ignition off.
• Measure the resistance between ground and the (P124) Left Front Passive Entry Handle Switch Return circuit.
Is the resistance below 5.0 Ohms?
Yes
• Replace the Left Front Exterior Door Handle (Passive Entry).
• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior
No
• Go to Test Step 4
Test Step 4 - (P124) LEFT FRONT PASSIVE HANDLE SWITCH RETURN WIRE OPEN
• Disconnect the Passive Entry Module C1 Harness connector.
• Measure the resistance of the (P124) Left Front Passive Entry Handle Switch Return circuit between the PEM C1 harness connector and the Left Front Exterior Door Handle Switch harness connector.
Is the resistance below 2.0 Ohms?
Yes
• Replace the Passive Entry Module.
• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior
No
• Repair the open in the (P124) Left Front Passive Entry Handle Switch Return wire.
• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior
Test Step 5 - (P125) LEFT FRONT PASSIVE ENTRY HANDLE SWITCH SENSE WIRE OPEN
11RT-B259A-00-5
• Turn the ignition off.
• Disconnect the Passive Entry Module C1 harness connector.
• Measure the resistance of the (P125) Left Front Passive Entry Handle Switch Sense wire between the PEM C1 harness connector and the Left Front Passive Entry Handle Switch harness connector.
Is the resistance below 2.0 Ohms?
Yes
• Go to Test Step 6
No
• Repair the open in the (P125) Left Front Passive Entry Handle Sense wire.
• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior
Test Step 6 - (P125) LEFT FRONT PASSIVE HANDLE SWITCH SENSE WIRE SHORTED TO GROUND
• Measure the resistance between ground and the (P125) Left Front Passive Entry Handle Switch Sense wire.
Is the resistance below 20K Ohms?
Yes
• Repair the short to ground in the (P125) Left Front Passive Entry Handle Switch Sense circuit.
• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior
No
• Go to Test Step 7
Test Step 7 - (P125) LEFT FRONT PASSIVE HANDLE SWITCH SENSE CIRCUIT SHORTED TO THE (P124) LEFT FRONT PASSIVE HANDLE SWITCH RETURN CIRCUIT
• Measure the resistance between the (P125) Left Front Passive Entry Handle Switch Sense circuit and the (P124) Left Front Passive Entry Handle Switch Return circuit.
Is the resistance below 20K Ohms?
Yes
• Repair the short between the (P125) Left Front Passive Entry Handle Switch Sense circuit and the (P124) Left Front Passive Entry Handle Switch Return circuit.
• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior
No
• Replace the Passive Entry Module.
• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior
