When replacing the ECM (SAE term: PCM) or the Transponder ECU a “handshake” procedure must be performed. This ECU ID communication is necessary to enable the Transponder ECU and the ECM to recognize each other before the vehicle will start. Complete ECU communication using the following steps: 1. Insert a Master key into the ignition cylinder. 2. Turn the ignition ON (engine OFF). 3. Short Tc and CG terminals of DLC3 using the Diagnostic Check Wire (SST 09843-18020 or equivalent) and leave for 30 minutes. 4. After 30 minutes, turn the ignition OFF and remove check wire from DLC3. 5. Register any additional keys as necessary. 6. Start the vehicle to confirm successful ECU communication. Key Programming: To program or delete a key, a registered Master key is necessary unless the Transponder ECU has been reset or replaced. The Transponder ECU system incorporates a black “Master” key and a gray “Sub” key. The process during registration of these two keys is identical. The key itself now determines if it functions as Master or Sub, not the registration procedure. The maximum number of allowable Master and Sub keys vary by model. Refer to the chart below.
