Symptoms

  • Check Engine light on
  • No communication with GPCM2 via diagnostic scanner
  • Glow plugs of the second group do not work
  • Difficult cold start
  • The pre-heating lamp lights up abnormally

Causes

  • Short circuit of the GPCM2 control wire to ground
  • Damaged insulation in the wiring harness
  • GPCM2 internal circuit malfunction (short to ground)
  • Moisture in the wiring harness
  • Mechanical cable damage

How to Fix

  1. Measure the voltage at the GPCM2 control pin (should change during data exchange)
  2. Disconnect GPCM2 and measure the wire resistance to ground (should be more than 100 kOhm)
  3. If a short circuit is detected, inspect the harness sequentially along the entire route
  4. Eliminate short circuit (repair insulation or replace conductor)
  5. If there is a short inside GPCM2, replace the module
  6. Check the ECU-GPCM2 connection after repair
