The PCM stores DTCs about the ACM system even if there is no electrical power such as when the battery negative terminal or No. A19 BACK UP Fl ECU (7.5 A) fuse are disconnected. Stored data based on failed parts should be cleared by using the CLEAR COMMAND of the HDS, if parts are replaced.
The HDS has two kinds of clear commands to meet this purpose. They are DTC clear, and ACM reset. The DTC clear command erases all stored DTC codes, freeze data, on-board snapshot, and readiness codes. This must be done with the HDS after reproducing the DTC during troubleshooting.
The PCM reset command erases all stored DTC codes, freeze data, on-board snapshot, readiness codes, and all specific data about the ACM system.
