Pinpoint Test
NOTE:
If the scan tool is unable to communicate with the PCM or access the transmission PIDs
, REFER to
INTRODUCTION - GASOLINE MODELS
.
- Read and record all DTCs
- Install the scan tool and record all DTCs .
Was DTC B1319:15 set?
- Yes: GO to 2 .
- No: The issue may not be the BSIA system. REFER to Symptom Chart: External Controls .
- Check the BSIA power circuit for an open
- Disconnect the selector lever C2008.
- Disconnect the BCM C2280B.
- Inspect for damaged or pushed out terminals.
- Measure the resistance of circuit CET53 (BU/OG) from the selector lever C2008-3 to the BCM C2280B-49.
Selector Lever BCM C2008 C2280B Pin Circuit Measurement / Action Pin Circuit 3 CET53 (BU/OG) 49 CET53 (BU/OG)
Is the resistance less than 5 ohms?
- Yes: GO to 3 .
- No: REPAIR circuit CET53 (BU/OG) for an open. CLEAR the DTC. TEST the system for normal operation.
- Check the BSIA ground circuit for an open
- Measure the resistance of circuit GD233 (BK) from the selector lever C2008-4 to ground.
Selector Lever Ground C2008 Ground Pin Circuit Measurement / Action Pin Circuit 4 GD233 (BK) Ground Ground
Is the resistance less than 5 ohms?
- Yes: GO to 4 .
- No: REPAIR circuit GD233 (BK) for an open. CLEAR the DTC. TEST the system for normal operation.
- Measure the resistance of circuit GD233 (BK) from the selector lever C2008-4 to ground.
- Check BSIA power circuit for voltage
- Ignition ON.
- Measure for voltage on circuit CET53 (BU/OG) from the selector lever C2008-3 to ground.
Selector Lever Ground C2008 Ground Pin Circuit Measurement / Action Pin Circuit 3 CET53 (BU/OG) Ground Ground Is any voltage present?
- Yes: REPAIR circuit CET53 (BU/OG) for a short to power. CLEAR the DTC. TEST the system for normal operation.
- No: INSTALL a new selector lever. REFER to Selector Lever .
