Are any high battery voltage and/or charging system Diagnostic Trouble Codes (DTCs) present in other modules?
Yes | Refer to the appropriate section in Group 414 for the procedure. |
|---|---|
No | GO to F2 |
F2 CHECK THE BATTERY VOLTAGE
Turn off all interior/exterior lights and accessories. Start and run the engine at approximately 2,000 rpm for 3 minutes while monitoring the battery voltage.
Does the battery voltage rise to 16.5 volts or higher?
Yes | DIAGNOSE the overcharging condition. Refer to the appropriate section in Group 414 for the procedure. |
|---|---|
No | GO to F3 |
F3 RECHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) B11D9:17
Ignition OFF. Ignition ON. Using a diagnostic scan tool, clear the SCCM Diagnostic Trouble Codes (DTCs) and repeat the self-test. Using a diagnostic scan tool, carry out the SCCM self-test.
Is DTC B11D9:17 present?
Yes | INSTALL a new SCCM. REFER to: Steering Column Control Module (SCCM) (211-05 Steering Wheel and Column Electrical Components, Removal and Installation). |
|---|---|
No | The system is operating normally at this time. The DTC may have been set previously during battery charging or while jump starting the vehicle. |
P2533:14
Refer to Wiring Diagrams Cell 13 for schematic and connector information.
Normal Operation and Fault Conditions
The BCMB check for voltage from the RUN/START circuit when the self-test is commanded. If no voltage is detected, DTC P2533:14 sets.
BCMB DTC Fault Trigger Conditions
DTC | Description | Fault Trigger Conditions |
|---|---|---|
P2533:14 Ignition Switch Run/Start Position Circuit: Circuit Short To Ground or Open | Sets during the on-demand self-test when the BCMB detects no voltage from the RUN/START input circuit. |
Possible Causes
Fuse Wiring, terminals or connectors BCM BCMB
PINPOINT TEST G : P2533:14
G1 CHECK FOR VOLTAGE TO THE BCMB (BODY CONTROL MODULE B)
Ignition OFF. Disconnect BCMB C4368A. Ignition ON. Measure:
