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.

Does the scan tool display: P0931-BTSI CONTROL CIRCUIT HIGH?

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 (Z101) BTSI SOLENOID GROUND CIRCUIT FOR AN OPEN





Turn the ignition off.

Disconnect the BTSI Solenoid harness connector.

Measure the resistance between ground and the (Z101) BTSI Solenoid Ground circuit.

Is the resistance above 5.0 ohms?

Yes

- Repair the (Z101) BTSI Solenoid Ground circuit for an open.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Go To 3

3. CHECK THE (K32) BTSI SOLENOID CONTROL CIRCUIT FOR AN OPEN





Disconnect the Instrument Cluster C1 harness connector.

Measure the resistance of the (K32) BTSI Solenoid Control circuit between the BTSI Solenoid harness connector and the Instrument Cluster C1 harness connector.

Is the resistance above 5.0 ohms?

Yes

- Repair the (K32) BTSI Solenoid Control circuit for an open.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Go To 4

4. CHECK THE 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 (K32) BTSI Solenoid Control circuit.

With the scan tool, actuate the BTSI Solenoid.

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
