Pinpoint Test N: DTC B125D:11 or 15
Refer to Wiring Diagram Set 117, Remote Keyless Entry and Alarm for schematic and connector information. Diagrams By Number
Normal Operation
If the circuitry to the start/stop switch (or the switch itself) fails, DTCs B125D:11 and/or B125D:15 may set. The run circuitry has dual circuits, so if one circuit fails, the second circuit will still allow the vehicle to be started.
- DTC B125D:11 (Ignition Run LED Circuit: Short To Ground) - a continuous memory and on-demand DTC that sets when the run LED output circuit from the Remote Function Actuator (RFA) module is shorted to ground on 3 consecutive test-cycles.
- DTC B125D:15 (Ignition Run LED Circuit: Short To Battery or Open) - a continuous memory and on-demand DTC that sets when the run LED output circuit from the RFA module is shorted to battery or is open on 3 consecutive test-cycles. The RFA module conducts a test-cycle on the run LED circuits during every start cycle.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Start/stop switch
- RFA module
PINPOINT TEST N: DTC B125D:11 OR 15
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
NOTE: The ignition must be OFF to carry out the RFA module self-test.
-------------------------------------------------
N1 CHECK THE DTCs
- Connect the scan tool.
- Clear the RFA module DTCs.
- Retrieve the RFA module DTCs.
- Is DTC B108:11 or 15 present?
Yes
REFER to Steering Column. Testing and Inspection
No
GO to N2.
-------------------------------------------------
N2 CHECK CIRCUIT CPK36 (VT/BN) FOR AN OPEN OR SHORT TO GROUND
- Disconnect: Start/Stop Switch C2195.
- Disconnect: RFA Module C2153d.
- Measure the resistance between the start/stop switch C2195-2, circuit CPK36 (VT/BN), harness side and the RFA module 2153d-8, circuit CPK36 (VT/BN), harness side; and between the start/stop switch C2195-2, circuit CPK36 (VT/BN), harness side and ground.
- Is the resistance less than 5 ohms between the start/stop switch and the RFA module; and greater than 10,000 ohms between the start/stop switch and ground?
Yes
INSTALL a new start/stop switch. If the concern is still present, GO to N3.
No
REPAIR the circuit. CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.
-------------------------------------------------
N3 CHECK FOR CORRECT RFA MODULE OPERATION
- Disconnect all the RFA module connectors.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect all the RFA module connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
Yes
INSTALL a new RFA module. RESET the parameters in both the RFA module and the PCM. REFER to Passive Anti-Theft System (PATS) Parameter Reset - Intelligent Access (IA) With Intelligent Access (IA). PROGRAM the IA keys into the new RFA module. REFER to Key Programming Using Diagnostic Equipment - Intelligent Access (IA) Intelligent Access (IA). TRANSFER the keyless entry keypad code into the new RFA module. REFER to Keyless Entry Keypad Code Programming in Locks. CYCLE the ignition. REPEAT the self-test. Testing and Inspection
No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test.
