PINPOINT TEST B: DTCs B10E7:11, 12 and 13

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

B1 CHECK THE RFA MODULE FOR DTCs
- Review the DTCs retrieved and recorded during Inspection and Verification.
- Is DTC B10E7:11, 12 or 13 present?
- Yes : For B10E7:11, GO to B2.
  For B10E7:12, GO to B3.
  
  For B10E7:13, GO to B4.
- No : For all other RFA module DTCs, REFER to the Master DTC Table in MULTIFUNCTION ELECTRONIC MODULES article.
B2 CHECK THE IGNITION RUN CIRCUIT FOR A SHORT TO GROUND
- Ignition OFF.
- Disconnect: RFA Module C2153B.
- Disconnect: SJB C2280B.
- Disconnect: Run/Start Relay.
- Measure the resistance between RFA module C2153B-5, circuit CDC34 (WH/OG), harness side and ground.

- Is the resistance greater than 10, 000 ohms?
- Yes : GO to B5.
- No : REPAIR circuit CDC34 (WH/OG). CARRY OUT an on-demand self test (required to clear certain DTCs). CORRECT any unresolved DTCs. CLEAR all DTCs. TEST the system for normal operation.
B3 CHECK THE IGNITION RUN CIRCUIT FOR A SHORT TO VOLTAGE
- Ignition OFF.
- Disconnect: RFA Module C2153B.
- Disconnect: SJB C2280B.
- Disconnect: Run/Start Relay.
- Ignition ON.
- Measure the voltage between RFA module C2153B-5, circuit CDC34 (WH/OG), harness side and ground.

- Is any voltage present?
- Yes : REPAIR circuit CDC34 (WH/OG). CARRY OUT an on-demand self test (required to clear certain DTCs). CORRECT any unresolved DTCs. CLEAR all DTCs. TEST the system for normal operation.
- No : GO to B5.
B4 CHECK THE IGNITION RUN CIRCUIT FOR AN OPEN
- Ignition OFF.
- Disconnect: RFA Module C2153B.
- Disconnect: SJB C2280B.
- Disconnect: Run/Start Relay.
- Measure the resistance between RFA module C2153B-5, circuit CDC34 (WH/OG), harness side and:
  - run/start relay pin 1, circuit CDC34 (WH/OG).
  - SJB C2280B-45 circuit CDC34 (WH/OG), harness side.

- Is the resistance less than 5 ohms?
- Yes : GO to B5.
- No : REPAIR circuit CDC34 (WH/OG). CARRY OUT an on-demand self test (required to clear certain DTCs). CORRECT any unresolved DTCs. CLEAR all DTCs. TEST the system for normal operation.
B5 ISOLATE THE RUN/START RELAY
- Carry out the appropriate relay component test on the run/start relay. Refer to COMPONENT TESTING article.
- Is the run/start relay OK?
- Yes : GO to B6.
- No : INSTALL a new run/start relay. CARRY OUT an on-demand self test (required to clear certain DTCs). CORRECT any unresolved DTCs. CLEAR all DTCs. TEST the system for normal operation.
B6 CHECK FOR CORRECT RFA MODULE OPERATION
- Disconnect: All RFA Module Connections.
- Check the RFA module connections for:
  - corrosion.
  - pushed-out pins.
  - spread terminals.
- Connect: All RFA Module Connections (make sure they are seated correctly).
- 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 article.
  CONFIGURE the new RFA module. REFER to Programmable Module Installation (PMI) in MODULE CONFIGURATION SYSTEM article.
  
  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 SYSTEM - PASSIVE ANTI-THEFT SYSTEM (PATS) article.
  
  PROGRAM 2 Intelligent Access (IA) key fobs. REFER to Key Programming Using Diagnostic Equipment-Intelligent Access (IA) in ANTI-THEFT SYSTEM - PASSIVE ANTI-THEFT SYSTEM (PATS) article. 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. CLEAR the DTCs. REPEAT the self-test.
