Test 9: Memory Interface Between Electronic Seat Adjustment

CONTROL MODULE & MIRROR/STEERING COLUMN CONTROL MODULE

NOTE: Ensure power seat memory function is operating properly before proceeding with this test.

NOTE: When checking voltage in this test, ensure voltmeter is set to measure AC voltage.

Disconnect mirror/steering column control module harness connector No. 2. See Figure . Measure AC voltage between ground and pin No. 12 at mirror/steering column control connector No. 2. Press any memory button. If 4-7 volts AC exists, interface circuit is okay at this time. If 4-7 volts AC does not exist, check wiring. See WIRING DIAGRAMS . If wiring is okay, replace electronic seat adjustment control module.
