Additional Information • Refer to 6 Wiring Diagram and Connector Chart for the following information: • PIM connector illustration and terminal assignment, and • PIM wiring diagram. • For intermittent fault conditions, refer to Intermittent Fault Conditions. • Since fault conditions in a wiring connector may trigger DTCs, always test the connectors related to this diagnostic Conditions for Running the DTC Conditions for running the DTC are: • The ignition is switched on. • The ignition voltage is 10.0 – 16.0 V. Conditions for Setting the DTC The DTC will set when the PIM detects a low voltage of <0.41 volts for one second. The DTC will set when the PIM detects a high voltage of >4.59 volts for one second. Action Taken When the DTC Sets When the DTC sets, there is no warning lamp displayed on the instrument cluster. Conditions for Clearing the DTC The DTC is cleared at the next ignition cycle. Refer to 4.1 Diagnostic General Descriptions for information on the conditions for clearing DTCs. Test Description The following numbers refer to the step numbers in the diagnostic table: 2 This step tests the vertical acceleration sensor using Tech 2. 6 This step tests the ground circuit.
Vertical Acceleration Sensor Diagnostic Table Step Action Yes No 1 Has the Diagnostic System Check been performed? Go to Step 2 Refer to additional information 2 1 Switch off the ignition for 30 seconds. 2 Start the engine. 3 Using Tech 2, select the DTC display function. Does DTC P0318 fail this ignition cycle? Go to Step 3 Refer to Additional Information in this DTC 3 1 Switch on the ignition with the engine not running. 2 Using a digital multimeter, measure the voltage between the Wiring Diagram and Connector Chart. Does the multimeter display approximately 5.0 V? Go to Step 4 Go to Step 7 |
