-> No GO to Pinpoint Test G531330t150.
G531330t150 : CHECK THE EMS RELAY TO ECM IGNITION CIRCUITS FOR 1. Measure the resistance between: EMS relay base, harness side ECM connector EC300, harness side Pin 05
Pin 04
Pin 05
Pin 06
Is either resistance greater than 5 ohms? -> Yes REPAIR the high resistance circuit. These circuits include fuses 2 and 12 of the front power distribution box. For additional information, refer to the wiring diagrams. CLEAR the DTC and test the system for normal operation.
-> No INSTALL a new EMS control relay. CLEAR the DTC and test the system for normal operation. PINPOINT TEST G531330p33 : G531330t80 : CHECK THE MAP SENSOR SUPPLY CIRCUIT VOLTAGE 1. Disconnect the MAP sensor electrical connector, PI29. 2. Key on, engine off. 3. Measure the voltage between: MAP sensor connector PI29, harness side Battery
Pin 02
Negative terminal
Is the voltage less than 4 volts? -> Yes REPAIR the 5 volt supply circuit between the MAP sensor and the ECM. For additional information, |
