Purpose:To determine if the PowertrainControl Module (PCM) has detected any fault conditions that would cause a hard start or no start condition. Key On Engine Off (KOEO) On-Demand Self Test is a functional test of the PCM performed on demand with the key on and the engine off. This test will check that all inputs…
Preparatory Steps: Clean debris. Using a 19 mm wrench, remove the plug and regulator valve. Clean and inspect the bore and regulator valve before assembly. CAUTION: In order to regulate the oil pressure, the valve must move freely in the bore Install the regulator and spring. Torque Value: 80 N•m [60 ft-lb]
Never operate the engine with the oil level below the “L” (Low) mark or above the “H” (High) mark. Wait at least 15 minutes after shutting off the engine to check the oil. This allows time for the oil to drain to the oil pan. NOTE The vehicle must be level when checking the oil…
Preparatory Steps: Drain the coolant. Remove the oil filter. Clean all debris from around the oil cooler. Using a 16 mm wrench, remove the turbocharger oil supply line from the oil filter head. Using a 10 mm wrench, remove the oil cooler cover, element and gaskets. Clean the sealing surfaces. Pressurize the element to 483 kPa…
Purpose:To determine if the injection control system can supply enough injection control pressure to sustain starting. Recommended Procedure:Connect OBDII Scan Tool to the data link connector (DLC) under the dash. Access ICP PID on Scan tool menu nd monitor ICP reading while cranking the engine. Note: CMP signal is required before injection control pressure is allowed…

Key On Engine Off (KOEO) Injector Electrical Self Test is a functional test of the PCM performed on demand with the key on and the engine off. This test determines if the injector circuits and solenoids are electrically operating without fault. All injectors will first buzz (audible feedback of the injector solenoids energizing the injector…
Preparatory Steps: Disconnect the cold starting aid, if used. Remove the air crossover tube. Remove high pressure fuel lines. Drain 2 liters (2.1 U.S. Quarts) of coolant. Using an 8 mm wrench, remove the coolant supply tube (1) and the coolant return tube (2). Remove the high pressure fuel lines. Using a 10 mm…
Preparatory Steps: Remove the high pressure fuel lines. Disconnect the cold starting aid, if used. Remove the air crossover tube (Industrial) With a 10 mm wrench, remove the manifold cover and gasket. NOTE: Plug the opening of air intake with a clean shop rag to prevent foreign material from entering combustion chamber. Clean the sealing surface….
