| + | ====== ECM Password Learn Procedure ====== | ||
| + | |||
| + | The TSM/TSSM/HFSM modules share a password with the ECM/ICM and Speedometer (2004-later) during operation. When replacing an ECM/ICM or TSSM/HFSM or Speedometer, you must go through a password learn procedure. If the procedure is not followed, the engine will start and run for a few seconds, and then stall. This will typically produce a P1009 or P1010 diagnostic code. | ||
| + | |||
| + | The learn procedure MUST be followed from start to finish without any interruption. If interrupted, starting over from the beginning is the only option. | ||
| + | |||
| + | **Connect the motorcycle up to a trickle charger and pull the headlight fuse before starting these steps, which take more than 30 minutes to complete.** | ||
| + | |||

| + | | If the engine starts but stalls, check DTCs for P1009 (Incorrect Pwd) or P1010 (Missing Pwd) ((See 2007 Harley-Davidson Sportster Electrical Diagnostic Manual Section 3.25, pg 3-72)) || | ||

| + | | | Ignition must be turned off for at least 15 seconds. | With ignition turned off, Check Engine Lamp and Security Lamp will be off. | Remember to pull the headlight fuse to prevent draining the battery. This procedure takes more than 30 minutes to complete. || | ||
| + | | 1 | Install new TSM/HFSM or ECM. | | || | ||
| + | | 2 | Set **RUN/STOP** switch to **RUN**. | | || | ||
| + | | 3 | Turn **IGN** key **ON**. | Verify Check Engine Lamp and Security Lamp illuminate and then turn off. | TSM/HFSM enables starter relay.|| | ||
| + | | 4 | Attempt normal start **one** time. | Engine starts and stalls. Check Engine Lamp illuminates and stays on. | Password has not been learned. ECM sets DTC P1009. || | ||
| + | | 5 | Wait ten seconds. Security lamp will illuminate and stay on. | Security Lamp illuminates. | ECM enters Password Learning mode for ten minutes. Do not cycle ignition switch or interrupt vehicle power or Password Learn will be unsuccessful.|| | ||
| + | | 6 | Wait until Security Lamp turns off. | | This takes ten minutes. (If no speedo or security light is available, wait **at least 10 minutes**.) || | ||
| + | | 7 | Quickly (within two seconds) turn **IGN** key OFF-**ON**. | | ECM must not be allowed to shutdown. || | ||
| + | | 8 | Wait until Security Lamp turns off. | | This takes ten minutes. (If no speedo or security light is available, wait **at least 10 minutes**.) || | ||
| + | | 9 | Quickly (within two seconds) turn **IGN** key OFF-**ON**. | | ECM must not be allowed to shutdown. || | ||
| + | | 10 | Wait until Security Lamp turns off. | | This takes ten minutes. (If no speedo or security light is available, wait **at least 10 minutes**.) || | ||
| + | | 11 | Quickly (within two seconds) turn **IGN** key OFF-**ON**. | | ECM must not be allowed to shutdown. || | ||
| + | | 12 | Turn **IGN** key **OFF**. __Wait 15 seconds before turning IGN on__. Turn **IGN** switch **ON** and start engine to confirm successful Password Learn procedure. Clear diagnostic trouble codes. | | || | ||
| + | | 13 | If the learn procedure is interrupted or fails in any way, you must restart your attempt from the beginning of the procecure! |||| | ||
