3. CHECK LINE PRESSURE CONNECTOR AND WIRING Ignition on, engine not running. With the scan tool, monitor the Line Pressure Sensor voltage while wiggling the wiring harness and connectors Did the voltage remain steady while wiggling the wiring harness and connectors? Yes >> Go To 4 No >> Disconnect and properly reconnect the Line Pressure Sensor/Variable Force Solenoid Assembly con- nector. Inspect terminals and repair as necessary. Perform 42RLE TRANSMISSION VERIFICATION TEST - VER 1. (Refer to 21 - TRANSMISSION/ 4. CHECK PCM AND WIRING Turn the ignition off to the lock position. Remove the Starter Relay. CAUTION: Removal of the Starter Relay will prevent the vehicle from being started in gear. WARNING: The Starter Relay must be removed from the PDC. Failure to do so can result in personal injury NOTE: Failure to remove the Starter Relay can cause a Transmission - No Response condition. With the Transmission Simulator select the 9 OFF 9 position on the 9 Input/Output Speed 9 switch. Ignition on, engine not running. With the scan tool, monitor the Line Pressure during the following step. With the Transmission Simulator, turn the selector switch to each of the 3 Line Pressure positions. NOTE: All three scan tool Line Pressure readings should be steady and ± 14 kPa or 2.0 psi of the reading Did the Line Pressure read within ± 14 kPa or 2.0 psi in all three positions? Yes >> Using the schematics as a guide, check the Powertrain Control Module (PCM) terminals for corrosion, damage, or terminal push out. Pay particular attention to all power and ground circuits. If no problems Perform 42RLE TRANSMISSION VERIFICATION TEST - VER 1. (Refer to 21 - TRANSMISSION/ No >> Repair internal transmission and inspect the oil pump per the Service information and replace if neces- sary. If no problems are found, replace the Line Pressure Sensor/Variable Force Solenoid Assembly — Perform 42RLE TRANSMISSION VERIFICATION TEST - VER 1. (Refer to 21 - TRANSMISSION/ 5. CHECK WIRING AND CONNECTORS The conditions necessary to set this DTC are not present at this time. Using the schematics as a guide, inspect the wiring and connectors specific to this circuit. Wiggle the wires while checking for shorted and open circuits. With the scan tool, check the DTC EVENT DATA to help identify the conditions in which the DTC was set. Where there any problems found? Yes >> Repair as necessary. Perform 42RLE TRANSMISSION VERIFICATION TEST - VER 1. (Refer to 21 - TRANSMISSION/ No >> Test Complete. 21 - 200 AUTOMATIC TRANSMISSION 42RLE - ELECTRICAL DIAGNOSTICS KJ |
