PCM Programming Procedures
Follow one of the procedures that describe the type of repair you performed:
Replaced the PCM (New)
• | Program the PCM (Flash). |
• | Operate the engine until the engine control temperature (ECT)
is more than 77°C (170°F) - auto top dead center (TDC) offset. |
Reprogram (Reflash) the PCM
Operate the engine until the ECT is more than 77°C (170°F) (auto
TDC offset).
Disconnect PCM/Reuse
The memory is OK.
Program the PCM
- Perform the set up. Make sure that the following conditions are
met:
• | The battery is charged. |
• | The battery/cig. lighter connection is secure. |
• | The data link connector (DLC) is attached. |
- Perform the programming procedure. Refer to up-to-date Techline
terminal/equipment for user instructions.
- Perform the Password Learn Procedure Seed and Key. Refer to
Programming Theft Deterrent System Components
in
Theft Deterrent.
- After the vehicle has been programmed, operate the vehicle until
the coolant temperature is more than 77°C (170°F). This will allow
the TDC offset to be programmed. Refer to PCM Programming, or the TDC offset,
if necessary.
- If the PCM is only being reprogrammed, the PCM maybe necessary
to perform a Glow Plug System Relearn. Refer to
Glow Plug System Relearn
.
- If the PCM fails to reprogram, do the following:
• | Check all of the PCM connections. |
• | Check the Techline terminal/equipment for the latest software
version. |
PCM Programming (TDC Offset)
The PCM will automatically activate the TDC offset program when the
engine coolant is more than 77°C (170°F). If the PCM is not programmed
with a TDC offset, a DTC P1214 will set.
