1. PERFORM POWER SEAT SYSTEM VERIFICATION TEST Disconnect all jumper wires and reconnect all previously disconnected components and connectors. Make sure that all accessories are turned off. Make sure that the battery is fully charged. Turn the ignition on. If either the Memory Seat Module (MSM) or the Driver Horizontal Seat Adjuster Motor/Seat Track was replaced, then the MSM Standard Routine must be performed using a scan tool. Using a scan tool, record and erase Diagnostic Trouble Codes (DTCs) from all modules. Operate the driver seat in all positions. Using the Memory Switch on the driver's door, program the driver's seat number 1 Button to a desired position and the driver's seat number 2 Button to a different position. Verify both Memory positions can be recalled with the Remote Keyless Entry (RKE) transmitter and with the Memory Switch on the driver's door. Turn the ignition off, wait 10 seconds, then turn the ignition on. Using a scan tool, select ECU View. Check for DTCs in the modules. Are DTCs present in any of the modules or is the original condition still present? Yes The repair is not complete. Perform the appropriate diagnostic procedure for the DTC or symptom that is still present. No The repair is complete.

1. PERFORM APS INTERMITTENT DIAGNOSTIC PROCEDURE WARNING: When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts, or fan. Do not wear loose clothing. Failure to follow these instructions can result in personal injury or death. The DTC is not active at this time. The following may help to identify an intermittent condition: Check for Technical Service Bulletins (TSBs) that may apply. Use DTC environmental data to try to duplicate the conditions in which the DTC was set. Turn the ignition off. Inspect the related wiring harness and connectors. Look for any chafed, pierced, pinched, partially broken wires, or broken, bent, pushed out, or corroded terminals. Perform a voltage drop test on the circuits between the component and the applicable module. If multiple DTCs are set, use a wiring schematic and inspect any common ground or supply circuits. Inspect and clean all ground circuits that are related to the most current DTC. Use the scan tool to perform a System Test or Actuation, if one applies to the component. Perform a wiggle test on the related wiring and connectors while monitoring the scan tool. Look for the DTC to reset or data to change during the test. A co-pilot, data recorder, and/or lab scope should be used to diagnose an intermittent condition. Were any problems found during the above inspection? Yes Repair as necessary. Perform APS VERIFICATION TEST - VER 1. Refer to «APS VERIFICATION TEST»(ref-481428-S05140725142012062200000) . No Test Complete.

1. Make sure all accessories are turned off and the battery is fully charged. Make sure all wiring and components are connected.
