3. A/C PRESSURE TRANSDUCER With the scan tool, monitor the A/C Pressure Transducer voltage. Is the voltage above 0.6 of a volt? Yes >> Replace the A/C Pressure Transducer. Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE) No >> Go To 4 4. (C18) A/C PRESSURE SIGNAL CIRCUIT SHORTED TO GROUND Turn the ignition off. Disconnect the C2 BCM harness connector. Measure the resistance between ground and the (C18) A/C Pressure Is the resistance below 100 ohms? Yes >> Repair the short to ground in the (C18) A/C Pressure Signal circuit. Perform the POWERTRAIN VERIFICATION TEST. (Refer to No >> Go To 5 5. (C18) A/C PRESSURE SIGNAL CIRCUIT SHORTED TO THE (K310) SENSOR GROUND CIRCUIT Measure the resistance between the (C18) A/C Pressure Signal circuit Is the resistance below 100 ohms? Yes >> Repair the short between the (K310) Sensor ground circuit and the (C18) A/C Pressure Signal circuit. Perform the POWERTRAIN VERIFICATION TEST. (Refer to No >> Go To 8 9 - 426 ENGINE ELECTRICAL DIAGNOSTICS KJ |
