Yes GO to H7. No INSTALL a new exterior door handle for the handle in question. REFER to Exterior Door Handle . - H7 CHECK THE LOCK AND UNLOCK CAPACITIVE SENSOR INPUT CIRCUIT FOR A SHORT TO GROUND
- Ignition OFF.
- Disconnect: RFA Module C2153D.
Is the resistance greater than 10, 000 ohms?
Yes GO to H16. No REPAIR the affected circuit. - H8 CHECK THE EXTERIOR DOOR HANDLE
- Disconnect: Suspect Front Exterior Door Handle.
- Connect a fused jumper wire:
Positive Lead Measurement / Action Negative Lead C543-2 C543-5 C634-2 C634-5
- Using a scan tool, perform the RFA module self-test.
Is DTC B1381:11 or B1382:11 present with the jumper wire connected?
Yes REMOVE the jumper wire. INSTALL a new exterior door handle for the handle in question. REFER to Exterior Door Handle . No REMOVE the jumper wire. GO to H9. - H9 CHECK THE LOCK AND UNLOCK CAPACITIVE SENSOR INPUT CIRCUIT FOR A SHORT TO VOLTAGE
- Ignition OFF.
- Disconnect: RFA Module C2153D.
- Ignition ON.
Is any voltage present?
Yes REPAIR the affected circuit. No GO to H10. - H10 CHECK THE LOCK AND UNLOCK CAPACITIVE SENSOR INPUT CIRCUIT FOR AN OPEN
- Ignition OFF.
Is the resistance less than 3 ohms?
Yes GO to H11. No REPAIR the affected circuit. - H11 CHECK THE LOCK AND UNLOCK CAPACITIVE SENSOR GROUND CIRCUIT FOR AN OPEN
Is the resistance less than 3 ohms?
Yes GO to H16. No REPAIR the circuit. - H12 CHECK THE EXTERNAL ANTENNA
- Disconnect: Suspect Front Exterior Door Handle.
- Measure:
Positive Lead Measurement / Action Negative Lead LH (Component Side) C543-3 , RH (Component Side) C634-3 LH (Component Side) C543-4 , RH (Component Side) C634-4
Is the resistance between 1 and 10 ohms?
Yes GO to H13. No INSTALL a new exterior door handle for the handle in question. REFER to Exterior Door Handle . - H13 CHECK THE EXTERNAL ANTENNA CIRCUITS FOR A SHORT TO VOLTAGE
- Ignition OFF.
- Disconnect: RFA Module C2153A.
- Ignition ON.
- Measure:
Positive Lead Measurement / Action Negative Lead C543-3 Ground C543-4 Ground C634-3 Ground C634-4 Ground
Is any voltage present?
Yes REPAIR the affected circuit. No GO to H14. - H14 CHECK THE EXTERNAL ANTENNA CIRCUITS FOR A SHORT TO GROUND
- Ignition OFF.
- Measure:
Positive Lead Measurement / Action Negative Lead C543-3 Ground C543-4 Ground C634-3 Ground C634-4 Ground
Are the resistances greater than 10, 000 ohms?
Yes GO to H15. No REPAIR the affected circuit. - H15 CHECK THE EXTERNAL ANTENNA CIRCUITS FOR AN OPEN
- Measure:
Positive Lead Measurement / Action Negative Lead C543-3 C2153A-17 C543-4 C2153A-18 C634-3 C2153A-19 C634-4 C2153A-20
Are the resistances less than 3 ohms?
Yes GO to H16. No REPAIR the affected circuit. - Measure:
- H16 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.
