PINPOINT TEST G: DTCs U3004:11 AND 12

NOTE: Use the Flex Probe Kit for all test connections to prevent damage to the wiring terminals. Do not use standard multimeter probes.

G1 REVIEW THE RFA MODULE DTCs
- Review the DTCs retrieved and recorded during Inspection and Verification.
- Is DTC U3004:11 or U3004:12 present?
  - Yes : For U3004:11, GO to G2.
    For U3004:12, GO to G4.
  - No : For all other RFA module DTCs, REFER to the Remote Function Actuator (RFA) Module DTC Chart .
G2 CHECK THE SMART KEYLESS ENTRY ACCESSORY RELAY CONTROL FOR A SHORT TO GROUND
- Ignition OFF.
- Disconnect: Smart Keyless Entry Accessory Relay.
- Measure the resistance between smart keyless entry accessory relay cavity 1, circuit ZA101 (OG), and ground.

- Is the resistance greater than 10,000 ohms?
  - Yes : INSTALL a new smart keyless entry accessory relay. CLEAR the DTC. TEST the system for normal operation.
  - No : GO to G3.
G3 ISOLATE THE SMART KEYLESS ENTRY ACCESSORY RELAY CONTROL CIRCUIT AND RECHECK FOR A SHORT TO GROUND
- Disconnect: RFA Module C3503C.
- Measure the resistance between smart keyless entry accessory relay cavity 1, circuit ZA101 (OG), and ground.

- Is the resistance greater than 10,000 ohms?
  - Yes : GO to G5.
  - No : REPAIR circuit ZA101 (OG). CLEAR the DTC. TEST the system for normal operation.
G4 CHECK THE SMART KEYLESS ENTRY ACCESSORY RELAY CONTROL CIRCUIT FOR A SHORT TO VOLTAGE
- Ignition OFF.
- Disconnect: RFA Module C3503C.
- Disconnect: Ignition Relay.
- Disconnect: Smart Keyless Entry Ignition Relay.
- Disconnect: Smart Keyless Entry Accessory Relay.
  NOTE: This step may cause one or more DTCs to set in the RFA module. Connect a fused jumper wire between ignition relay cavity 3, circuit SBB07 (WH/RD) and ignition relay cavity 5, circuit CDC21 (GY/BN).

- Is any voltage present?
  - Yes : REPAIR circuit ZA101 (OG). CLEAR the DTC. TEST the system for normal operation.
  - No : GO to G5.
G5 CHECK FOR CORRECT RFA MODULE OPERATION
- Disconnect all RFA module electrical connectors.
- Check connectors for:
  - corrosion
  - pushed-out pins
  - bent pins
  - spread terminals
- Connect all RFA module electrical connectors and make sure they are seated correctly.
- Connect: Ignition Relay.
- Connect: Smart Keyless Entry Accessory Relay.
- Connect: Smart Keyless Entry Ignition Relay.
- Operate the system and verify the concern is still present.
- Is the concern still present?
  - Yes : INSTALL a new RFA module. REFER to MULTIFUNCTION ELECTRONIC MODULES .
    CONFIGURE the new RFA module. REFER to Programmable Module Installation (PMI) in MODULE CONFIGURATION .
    
    CARRY OUT a Passive Anti-Theft System (PATS) Parameter Reset. REFER to Passive Anti-Theft System (PATS) Parameter Reset-Intelligent Access (IA) in ANTI-THEFT - PASSIVE ANTI-THEFT SYSTEM (PATS) .
    
    PROGRAM 2 Intelligent Access (IA) keys. REFER to Key Programming Using Diagnostic Equipment-Intelligent Access (IA) in ANTI-THEFT - PASSIVE ANTI-THEFT SYSTEM (PATS) .
    
    TEST the system for normal operation.
  - No : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. TEST the system for normal operation.
