Series 60 DDEC V Troubleshooting – Section 11.5 Improper Injector Calibration Setting (DDEC V Engines Only)

Section 11.5
Improper Injector Calibration Setting (DDEC V Engines Only)

To determine if improper injector calibration setting (DDEC V engines only) is causing rough running or stalling, perform the following steps:‪

1. Test for improper injector setting.
2. Compare the calibration code(s) shown on the Detroit Diesel Diagnostic Link display with the two digit calibration code(s) on the injector(s). See Figure "Injector Calibration Code" .
   

   Figure 1. Injector Calibration Code

   1. If the calibration codes match, check compression pressure; refer to "11.6 Low Compression Pressure" .
   2. If the calibration code on the display is different then the calibration code on the suspect injector for that cylinder, the injector setting must be reset, see Figure "Injector Calibration Code" ; refer to "11.5.1 Improper Injector Setting Repair" .

Section 11.5.1
Improper Injector Setting Repair

Perform the following steps to recalibrate improper injector setting:‪

1. Reset incorrect injector setting.
2. Verify injector setting repair; refer to "11.5.1.1 Test the Engine with Corrected Injector Setting" .

Section 11.5.1.1
Test the Engine with Corrected Injector Setting

Perform the following steps to determine if the corrected injector setting resolved rough running or stalling: ‪

1. Start and run the engine.
2. Run the engine through its operating range with no-load for approximately 5 minutes, allowing the engine coolant to reach normal operating range, 88-96°C (190-210°F).
   1. If the engine is not running rough or stalling, no further troubleshooting is required. Shut down the engine.
   2. If the engine is running rough or stalling, shut down the engine. Check for low compression pressure; refer to "11.6 Low Compression Pressure" .
