• Suspect faulty PSE control module.

If vehicle does not unlock and pump in PSE control module runs, check the following as possible cause and repair as necessary:

• Perform pneumatic system TEST 1: PSE CONTROL MODULE VOLTAGE SUPPLY (CIRCUIT 30). See PNEUMATIC SYSTEM EQUIPMENT (PSE) under SYSTEM TESTS .
• Retrieve keyless entry system DTCs. See KEYLESS ENTRY SYSTEMS article.
• Perform central locking vacuum TEST 1: CENTRAL LOCKING SYSTEM PRESSURE CHECK. See CENTRAL LOCKING under VACUUM SYSTEM TESTS .
• Perform central locking vacuum TEST 3: INDIVIDUAL COMPONENT PRESSURE TESTS. See CENTRAL LOCKING under VACUUM SYSTEM TESTS .
• Perform pneumatic system vacuum TEST 2: CENTRAL LOCKING SYSTEM PRESSURE SUPPLY (DRIVER'S DOOR). See PNEUMATIC SYSTEM EQUIPMENT under VACUUM SYSTEM TESTS .
• Perform pneumatic system vacuum TEST 4: CENTRAL LOCKING SYSTEM PRESSURE SUPPLY (PASSENGER'S DOOR, REAR DOORS & TRUNK LID LOCK). See PNEUMATIC SYSTEM EQUIPMENT under VACUUM SYSTEM TESTS .
• Perform pneumatic system vacuum TEST 6: CENTRAL LOCKING SYSTEM PRESSURE SUPPLY (TRUNK LID LOCK). See PNEUMATIC SYSTEM EQUIPMENT under VACUUM SYSTEM TESTS .
• Perform pneumatic system vacuum TEST 8: CENTRAL LOCKING SYSTEM PRESSURE SUPPLY (FUEL DOOR). See PNEUMATIC SYSTEM EQUIPMENT under VACUUM SYSTEM TESTS .
