Possible Causes
- Network communication concern
- FCIM concern
Harness Side
| Circuit | Pin |
Harness Side
| Circuit | Pin |
|---|---|
| B+ (Battery Positive Voltage) - SBP12 | 26 (GREEN/RED) |
| GND (Ground) - GD216 | 1 (BLACK/VIOLET) |
- CG1: CHECK FOR MODULE DTCS
- Ignition ON, engine OFF.
- Retrieve the continuous memory DTCs.
- Are there DTCs present in ANY module?
Yes No DIAGNOSE all DTCs before diagnosing the selectable drive mode feature. Go to CG2. - CG2: CHECK FCIM COMMUNICATIONS WITH THE SCAN TOOL
- Review the results from the previous step.
- Did the FCIM communicate with the diagnostic scan tool?
Yes No Go to CG3. DIAGNOSE the no communication concern with the FCIM. REFER to appropriate service information - CG3: CHECK FOR DTCS IN THE FCIM
Carry out the FCIM self-test.
- Are any DTCs present in FCIM?
Yes No DIAGNOSE the FCIM DTCs. REFER to appropriate service information.. Go to CG4. - CG4: CHECK THE FCIM VOLTAGE CIRCUIT FOR AN OPEN
- Ignition OFF.
- FCIM_A connector disconnected. (C2402A)
- Measure the voltage between:
(+) FCIM_A (C2402A) Connector, Harness Side (-) B+ - SBP12 (GREEN/RED) - Pin 26 Ground - Is the voltage greater than 11 volts?
Yes No Go to CG5. VERIFY the FCIM fuses in the BJB are OK. REFER to Wiring Diagramsfor fuse information.
If the fuse is OK, REPAIR the circuit.
If the fuse is not OK, REFER to the Wiring Diagrams to identify the cause of the circuit short. - CG5: CHECK THE FICM GROUND CIRCUIT FOR AN OPEN
- Measure the resistance between:
(+) FCIM_A (C2402A) Connector, Harness Side (-) GND - GD216 (BLACK/VIOLET) - Pin 1 Ground - Is the resistance less than 3 ohms?
Yes No Go to CG6. REPAIR the circuit. - CG6: VERIFY FCIM OPERATION
- Disconnect all FCIM electrical connectors.
- Using a good light source, inspect all disconnected electrical connectors for the following:
- corrosion - install new connector or terminal and clean the module pins
- damaged or bent pins - install new terminals or pins
- pushed-out pins - install new pins as necessary
- spread terminals - install new terminals as necessary
- Connect all FCIM electrical connectors. Make sure they seat and latch correctly.
- Ignition ON, engine OFF.
- Wait 2 minutes for the FCIM to initialize.
- Operate the system and verify the concern is still present.
- Is the concern still present?
| Yes | No |
|---|---|
| INSTALL a new FCIM. CHECK OASIS for any service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no services articles address this concern, INSTALL a new FCIM. REFER to appropriate service information |
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues. |
