DTC U2006, Transmitted SPI Clock Output Low
- If BFC diagnostic system check was performed, go to next step. If BFC diagnostic system check was not performed, go to BFC DIAGNOSTIC SYSTEM CHECK .
- Disconnect BFC 24-pin, Pink connector C3. Turn ignition on. Using DVOM, check voltage at BFC harness connector C3, terminal A7 (Pink/Black wire). If battery voltage exists, go to next step. If battery voltage does not exist, go to step 6).
- Check for a poor connection at BFC connector C3, terminal A7 (Pink/Black wire). If a poor connection exists, go to next step. If connection is okay, go to step 5).
- Repair poor connection at BFC connector C3, terminal A7 (Pink/Black wire). Go to step 13).
- Replace BFC. See REMOVAL & INSTALLATION . Go to step 13).
- Disconnect instrument cluster connector. See INSTRUMENT PANEL article. Using DVOM, check resistance between BFC harness connector C3, terminal A7 (Pink/Black wire) and instrument cluster harness connector terminal A10 (Pink/Black wire). If resistance is 0-2 ohms, go to next step. If resistance is not 0-2 ohms, go to step 8).
- Check resistance between BFC harness connector C3, terminal A7 (Pink/Black wire) and ground. If resistance is infinite, go to step 10). If resistance is not infinite, go to step 9).
- Repair open in Pink/Black wire between BFC connector C3 and instrument cluster. Go to step 13).
- Repair short to ground in Pink/Black wire between BFC connector C3 and instrument cluster. Go to step 13).
- Check for a poor connection at instrument cluster connector terminal A10 (Pink/Black wire). If a poor connection exists, go to next step. If connection is okay, go to step 12).
- Repair poor connection at instrument cluster connector terminal A10 (Pink/Black wire). Go to step 13).
- Replace instrument cluster. See INSTRUMENT PANEL article. Go to next step.
- Clear DTCs. Perform BFC DIAGNOSTIC SYSTEM CHECK .
