B0930
P0930-BTSI CONTROL CIRCUIT LOWP0930 - BTSI Control Circuit Low:
WHEN MONITORED
With the ignition in the Unlock or Run position and the driver's foot applied to the brake pedal.
SET CONDITION
The Instrument Cluster detects a low value on the BTSI Solenoid Control circuit.
POSSIBLE CAUSES
- (B30) BTSI solenoid control circuit shorted to the (Z101) BTSI solenoid ground circuit
- (B30) BTSI solenoid control circuit shorted to ground
- Transmission unlock solenoid (BTSI)
- Instrument cluster
Diagnostic Test
1. TEST FOR INTERMITTENT CONDITION
Turn the ignition on.
With the scan tool, record and erase DTCs.
Turn the ignition off, wait 10 seconds then turn the ignition on.
Apply and release the brakes.
With the scan tool, read DTCs.
Q: Does the scan tool display: P0930-BTSI CONTROL CIRCUIT LOW?
YES: Go To 2
NO: The condition that caused this code to set is not present at this time. Using the wiring diagram as a guide, inspect the wiring and connectors for an intermittent condition. Operate the system several times and recheck for active DTCs. Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test
2. CHECK THE (B30) BTSI SOLENOID CONTROL CIRCUIT FOR A SHORT TO THE (Z101) BTSI SOLENOID GROUND CIRCUIT.
Turn the ignition off.
Disconnect the BTSI solenoid harness connector.
Disconnect the Instrument Cluster C1 harness connector.
Measure the resistance between the (B30) BTSI Solenoid Control Circuit and the (Z101) BTSI Solenoid Ground Circuit.
Q: Is the resistance below 5.0 ohms?
YES: Repair the (B30) BTSI Solenoid Control circuit for a short to the (Z101) BTSI Solenoid Ground Circuit. Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test
NO: Go To 3
3. CHECK THE (B30) BTSI SOLENOID CONTROL CIRCUIT FOR A SHORT TO GROUND
Measure the resistance between ground and the (B30) BTSI Solenoid Control circuit.
Q: Is the resistance below 5.0 ohms?
YES: Repair the (B30) BTSI Solenoid Control circuit for a short to ground. Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test
NO: Go To 4
4. CHECK OPERATION OF THE BTSI SOLENOID
Reconnect the Instrument Cluster C1 harness connector.
Turn the ignition on.
Using a 12 volt test light connected to ground, check the BTSI Solenoid Control circuit.
With the scan tool, actuate the BTSI Solenoid.
Q: Does the test light illuminate brightly?
YES: Replace the Transmission Unlock (BTSI) Solenoid. Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test
NO: Replace the Instrument Cluster. Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test
