Note. A hard start/no start concern with the engine oil temperature (EOT) below 15°C (60°F) perform Step 11 first.

Glow Plug System Operation

  1. Glow Plug Control Module (GPCM) Operation Glow plug ON time is dependent on oil temperature and altitude. The GPCM will command the glow plugs on for 1 to 120 seconds. The GPCM does not operate if the oil temperature is above 55°C (131°F). Connect the scan tool. Access and retrieve the KOEO and continuous DTCs. If GPCM DTCs are present, GO to «PINPOINT TEST AF: GLOW PLUG SYSTEM»(ref-225542-S11057899972006031800000) . Verify B+ voltage is supplied to the GPCM. Access and monitor the GPCTM and EOT PIDS to verify sufficient glow plug "ON" time. Turn the key to the ON position and measure the glow plug voltage ("ON" time). NOTE: The Wait To Start indicator "ON" time (1 -10 seconds) is independent from glow plug "ON" time. On Time Specification Measurement 1 to 120 seconds B+
  2. Glow Plug Resistance Disconnect the glow plug bus bar connector. Measure the resistance between the glow plug bus bar connector, component side and battery ground. Disconnect the GPCM. Measure the resistance between the GPCM connector, harness side and the glow plug bus bar connector, harness side.
