Action Taken When the DTC Sets
* The tilt motor will be deactivated.
* Memory recall functions will be disabled.

* A current DTC will clear when the failed switch input is no longer active.
* A history DTC will clear after 100 ignition cycles.
Diagnostic Aids
An intermittently stuck tilt switch may cause a DTC to set.

Circuit/System Verification
Ignition ON,observe the scan tool Tilt Up Switch parameter and Tilt Down Switch parameter while cycling the switch between states.The reading
should be Inactive and change to Active when pushing the appropriate switch.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at the tilt switch.
2. Ignition ON, verify a test lamp illuminates between the B+ circuit terminal B and ground.
瀚慖f the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
3. Verify the scan tool tilt switch parameter is Inactive.
瀚慖f not the specified value, test the control circuit listed below for a short to voltage. If the circuit tests normal, replace the MSM.
* Tilt Up Switch terminal C
* Tilt Down Switch terminal A
4. Install a 3A fused jumper wire between the control circuits listed below and the B+ circuit terminal. Verify the scan tool tilt switch parameter
is Active.
* Tilt Up Switch terminal C
* Tilt Down Switch terminal A
瀚慖f not the specified value, test the appropriate control circuit for a short to ground or an open/high resistance. If the circuit tests normal,
replace the MSM.
5. If all circuit test normal, test or replace the tilt switch.
