- P1226 (injector 2 output circuit), P0302 (cylinder #2 misfire), U0073 (CAN bus reset counter overrun), U0105 (lost comm with fuel injection control module), and U0101 (lost comm with TCM) areal stored faults. No diagnostic information available on ShopKey or AllData, found an online service manual but it does not have any of these faults listed. Clear fault codes and road tested – no faults returned and no driveability issues felt.
- Remove and reinstall left upper speaker to disconnect visor light. Reprogrammed both remotes and verify proper operation.
