Yes GO to I6. No GO to I8. - I6 CHECK THE LIFTGATE RELEASE SWITCH FOR A SHORT TO GROUND
- Disconnect: Liftgate Release Switch.
- Using a scan tool, clear the RFA module DTCs.
- Using a scan tool, perform the RFA module self-test.
Is DTC B113E:11 retrieved again?
Yes GO to I7. No INSTALL a new exterior liftgate release switch. REFER to Liftgate Release Switch . - I7 CHECK THE LIFTGATE RELEASE SWITCH INPUT CIRCUIT FOR A SHORT TO GROUND
- Ignition OFF.
- Disconnect: RFA Module C2153B.
- Measure:
Positive Lead Measurement / Action Negative Lead C4216-2 Ground
Is the resistance greater than 10, 000 ohms?
Yes GO to I17. No REPAIR the circuit. - I8 CHECK THE RFA MODULE EXTERNAL TRUNK SWITCH (Trunk_Ext_Sw) PID
- Using a scan tool, view RFA module PIDs.
- Press the liftgate release switch while monitoring the RFA module PID Trunk_Ext_Sw.
Does the PID indicate the switch is being pressed?
Yes GO to I12. No GO to I9. - I9 CHECK THE EXTERIOR LIFTGATE RELEASE SWITCH
- Disconnect: Liftgate Release Switch.
- Using a scan tool, view RFA module PIDs.
- Monitor the RFA module PID Trunk_Ext_Sw.
Does the PID indicate that the switch is being pressed?
Yes REMOVE the jumper wire. INSTALL a new exterior liftgate release switch. REFER to Liftgate Release Switch . No REMOVE the jumper wire. GO to I10. - I10 CHECK THE LIFTGATE RELEASE SWITCH GROUND CIRCUIT FOR AN OPEN
- Using a scan tool, view RFA module PIDs.
- Monitor the RFA module PID Trunk_Ext_Sw.
- Connect a fused jumper wire:
Positive Lead Measurement / Action Negative Lead C4216-2 Ground
Does the PID indicate that the switch is being pressed?
Yes REMOVE the jumper wire. REPAIR the circuit. No REMOVE the jumper wire. GO to I11. - I11 CHECK THE LIFTGATE RELEASE SWITCH INPUT CIRCUIT FOR AN OPEN
- Ignition OFF.
- Disconnect: RFA Module C2153B.
Is the resistance less than 3 ohms?
Yes GO to I17. No REPAIR the circuit. - I12 CHECK THE LIFTGATE IA ANTENNA
- Ignition OFF.
- Disconnect: Liftgate Intelligent Access (IA) Antenna.
- Measure:
Positive Lead Measurement / Action Negative Lead (Component Side) C4082-1 (Component Side) C4082-2
Is the resistance between 0.3 and 0.6 ohms?
Yes GO to I13. No INSTALL a new liftgate IA antenna. REFER to or Liftgate Intelligent Access (IA) Antenna. - I13 CHECK THE LIFTGATE IA ANTENNA CIRCUITS FOR A SHORT TO VOLTAGE
- Disconnect: RFA Module C2153A.
- Ignition ON.
Is any voltage present?
Yes REPAIR the affected circuit. No GO to I14. - I14 CHECK THE LIFTGATE IA ANTENNA CIRCUITS FOR A SHORT TO GROUND
- Ignition OFF.
Are the resistances greater than 10, 000 ohms?
Yes GO to I15. No REPAIR the affected circuit. - I15 CHECK THE LIFTGATE IA ANTENNA CIRCUITS FOR A SHORT TO EACH OTHER
Are the resistances greater than 10, 000 ohms?
Yes GO to I16. No REPAIR the circuits. - I16 CHECK THE LIFTGATE IA ANTENNA CIRCUITS FOR AN OPEN
Are the resistances less than 3 ohms?
Yes GO to I17. No REPAIR the affected circuit. - I17 CHECK FOR CORRECT RFA MODULE OPERATION
- Ignition OFF.
- Disconnect and inspect all RFA module 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 all RFA module 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 TSBs. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs address this concern, INSTALL a new RFA module. REFER to Multifunction Electronic Modules . 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.
