3. Wait for 6 seconds or more.

Are DTCs B1001, B1008, B1011, B1032, B1750, and/or B1900 also indicated with DTC B1150?
YES - Troubleshoot DTC B1000.

NO - If only DTC B1150 is present, replace the gauge control module (tach) assembly. If no DTCs are present, it's an intermittent failure, the system is OK at this time. Check for loose or poor connections at the gauge control module (tach) 36P connector, and at under-dash fuse/relay box connector Q (16P).
