Diagnosis And Testing - Memory Switch
- Remove the memory set switch from the drivers door panel (Refer to REMOVAL
).
- Using an ohmmeter, check the continuity of the memory select switch MUX circuit between the C2 wire harness connector for the body control module and the wire harness connector for the memory switch. There should be continuity. If OK, go to Step 3. If not OK, repair the open or shorted MUX circuit as required.
- Using an ohmmeter, check the continuity of the memory select switch return circuit between the C2 wire harness connector for the body control module and the wire harness connector for the memory switch. There should be continuity. If OK, go to Step 4. If not OK, repair the open or shorted return circuit as required.
- Using an ohmmeter, test the resistances of the memory switch at the pins in the switch connector receptacle in each switch position. See the Memory Switch Test Table. If OK, refer to DIAGNOSIS AND TESTING - MEMORY SYSTEM
. If not OK, replace the faulty memory set switch.
