Reprogramming Using Boot Key

When working in the prototype phase with newly created .srz files from MotoHawk, it possible to program an .srz with errors in the CAN software or in the model that prevent communications with the module once programmed. When this happens, the module appears to be locked up or frozen when accessing the module via MotoTune. In this case, use the Boot Key to force the module into reboot mode such that a known, valid .srz can be reprogrammed into the module.

The Boot Key has a 10 pin CAN connector that should be inserted into an open port on the CAN junction box. The device generates a 555 Hz, 0-Vbatt, 50% duty cycle square wave signal out of pin E when power is applied to pin A and ground applied to pin B. When this signal is received on the appropriate pin of the module when the module wakes, it is forced into reboot mode and will allow the module to be reprogrammed.

Boot Key vs Boot Harness

Some modules are recovered using the boot key, while others are recovered with a boot harness. The process is the same.

Modules that are Recovered with a Boot Key

The boot key can be used to recover the following modules:

  • ECM-0555-48
  • ECM-0555-80
  • GCM/HCM-0563-48(except GCM-0563-048-0802)
  • ECM-0565-128
  • ECM-55xx-112
  • ECM-3R (ECM-0565-218-052-0600)
  • SECM112 main processor
  • PCM112-14 main processor
  • SECM70


Woodward Part Number: 1635-1800 Boot Key

Modules that are Recovered with a Boot Harness

The following modules use a boot cable for recovery rather than a boot key, but the recovery process is the same.

  • ECM-S12X-070 -- boot cable 5404-1144
  • HCM-0563-048 -- boot cable 5404-1138
  • GCM-0563-048 -- boot cable 5404-1138
  • ECM-0563-048 -- boot cable 5404-1123
  • GCM-0S12-024 -- boot cable 5404-1213
  • ECM-0S12-024 -- boot cable 5404-1238
  • SECM112 -- boot cable p/n TBD.
  • PCM112-14 Auxiliary processor

The boot cable creates a sequence of High/Lows on the Analog inputs of the module, rather than a 555 Hz boot signal on a specified module pin.

Note: SECM112 main processor can be recovered with either a boot key or with a boot harness. See below for additional information.

Recovering the Module

IMPORTANT: Remove the module from all control connections before attempting to recover it with a boot key. The module should be isolated on the communications bus.


Wiring Connections

Boot Key

Plug the Boot Key into the junction box and make sure that power and ground are connected to pins A (Batt) and B (ground) on the junction box. Connect pin E of the junction box to the STOP pin of the module. Some modules do not have a STOP pin, use the pin listed below instead.

  • PCM128_563 – DG1
  • SECM112 main processor - DG8

If you are using a development harness and the 128-pin module, you will need to move the fuse position to 'boot'

Boot Harness

Connect the boot harness to the ECU and move the switch position to 'boot'. The sequence of analog inputs shown below can also be used instead of the boot harness.

MotoServer Port Setup for Module Recovery

The MotoServer Port must be set to CAN1, PCM-1, Baud Rate 250kbps. The CityID should be set to CityID 11 (0x0B) with the following exceptions:

  • ECM-0S12-024 which has default City Id of 0x81, except the -0804 which has default City ID of 0X0B
  • GCM-0S12-024 which has default City ID of 0x91
  • SECM112 auxiliary processor has default CityID of 0x81.
  • PCM112-14 auxiliary processor has default CityID of 0x81.

Programming the Module

  1. Turn the Power and Key Off.
  2. Turn on the Power, but leave the Key OFF.
  3. Select a known good SRZ file, and begin programming in MotoTune
  4. When the “Looking for an ECU” prompt appears in the dialogue box, turn on key power to the ECU. The module must “wake-up” with the boot key or boot signal applied in order to force a reboot.

Boot Key Recovery of SECM112

The SECM112 is different in that it has two microprocessor cores, the main processor and the auxiliary processor. The processors are connected on CAN1, so it is important that the baud rate of both processors on CAN1 be the same. The processors must also communicate with MotoTune on different city-id's.
