====== 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)) ||
^ Device Being Serviced ^ Password Learn Procedure Required |
| TSM replacing TSM |  NO  |
| TSM replacing HFSM or TSSM |  YES  |
| HFSM or TSSM new unit installed |  YES  |
| ECM new unit installed |  YES  |
| Speedometer new unit installed |  YES  |

===== Setting TSM/HFSM and ECM Password =====

^ Step # ^ Action ^ Confirmation ^ Notes  | ((See 2007 Harley-Davidson Sportster Electrical Diagnostic Manual Section 3.25, pg 3-73)) |
| | 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! ||||
