Pcm Coding (All Models)

2001 Mitsubishi Montero XLSSECTION Pcm Coding (All Models)
NOTE: VAG 1551 scan tool is necessary to perform PCM coding.

If Powertrain Control Module (PCM) is replaced it is necessary to code new PCM. If new PCM is not properly coded, the following problems may occur:

  • Driveability problems (i.e. harsh shifting).
  • Increased fuel consumption.
  • Increased exhaust emissions.
  • Reduction in transmission life.
  • Malfunctions not present are stored in PCM memory.
  • Not all PCM functions are carried out (i.e. EVAP system operation).

Following manufacturer's instructions, connect VAG 1551 scan tool to vehicle. Following manufacturer's instructions, access PCM coding information using VAG 1551 scan tool. For PCM coding options, see appropriate ECM CODING OPTIONS table.

As an example, a properly coded PCM for an A4 model with EGR system, All Wheel Drive (AWD), and Automatic Transmission (A/T) would look like 01251 on the VAG 1551 scan tool.

NOTE: After coding PCM and starting engine for first time, allow engine to idle for several minutes so PCM can go through a learn function. Idle speed may be erratic while PCM is learning.
