Pinpoint Test K : B108A:12: Notes
Diagnostic Overview
B108A:12
Refer to Power Distribution/BCM for schematic and connector information.
Normal Operation and Fault Conditions
NOTE:
The RFA module is only capable of setting DTC B108A:12 as a continuous memory DTC. It is possible for this DTC to be cleared and not return even if the condition that caused it is still present. If DTC B108A:12 is retrieved, carry out this pinpoint test even if the DTC does not return.
Fused battery voltage is sent to one set of contacts in the start/stop switch from BCM fuse 28 (15A). When the switch is pressed, this voltage is sent to the BCM, the RFA module and the PCM. The other set of contacts in the start/stop switch connects the BCM to ground. When the switch is pressed, the BCM detects this ground signal and takes appropriate action.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B108A:12 | Start Button: Circuit Short to Battery | This DTC sets if the RFA module detects a short to voltage on the start/stop switch input circuit, or if start/stop switch is stuck in the closed position. |
