TRANSMISSION CONTROL SYSTEM (4L30–E) 7A1–59 D When diagnosing for a possible intermittent short or D An open ignition feed circuit can cause multiple DTCs Test Description The numbers below refer to the step numbers on the from the ignition through the PCM. 4. This test measures the resistance of the component. 8. This test checks the function of the shift solenoid A and the transmission internal wiring harness. Shift Solenoid Status Chart Gear Shift solenoid A Shift solenoid B 1st OFF ON 2nd ON ON 3rd ON OFF 4th OFF OFF DTC P0753 Shift Solenoid A Electrical Step Action Yes No 1 1. Install the scan tool. NOTE: Before clearing DTC(s), use the scan tool to record “Failure 3. Record the DTC “Failure Records”. Were DTCs P0753, P0758, P1860 set? Go to Step 2 Go to Diagnostic Aids 2 1. Turn the ignition “on”. connector terminals J3–E14 and J2–C8 (GND). Is the voltage within 10–12 volts? Go to Step 3 Go to Step 4 3 1. Turn the ignition “off”. connector terminals J3–F14 and ground. Is the voltage within 10 – 12 volts? Go to Step 10 Go to Step 4 4 1. Turn the ignition “off”. PCM connector terminals J3–E14 and J3–F14. Is the resistance within 18 – 20 ohms? Go to Step 5 Go to Step 6 5 1. Disconnect the J1 (RED) and J2 (WHITE) PCM connectors. terminals J3–F14 and ground. Is there a continuity? Go to Step 11 Go to Step 7 6 1. Disconnect the 16–way harness connector H–53. terminals H53–14 and H53–15. Is the resistance within 18–20 ohms? Go to Step 13 Go to Step 8 7 Using the J39200 DVOM, check a continuity between J3 (BLUE) Is there a continuity? Go to Step 12 Go to Step 9 8 1. Disconnect the transmission main case 4 pin connector M–7. terminals M7–3(D) and M7–4(C). Is the resistance within 18–20 ohms? Go to Step 14 Go to Step 15 |
