Battery voltage is supplied to the adjustable pedal switch from the memory seat module (MSM). When the pedal switch is operated to move the pedals forward, battery voltage is applied through the switch contacts and the adjustable pedal forward switch signal circuit to the MSM. In response to this signal, the MSM applies battery voltage through the adjustable pedal motor forward control circuit and ground through the adjustable pedal motor rearward control circuit to the motor. The motor runs to move the pedals forward until the switch is released. Moving the pedals rearward works similarly to moving the pedals forward, except that battery positive voltage and ground are applied on the opposite circuits causing the motor to run in the opposite direction.

The MSM may be referenced as the driver position module.

Ignition ON, observe the scan tool Pedal Forward Switch and Pedal Aft Switch parameters while pressing and releasing the pedal switch in both directions. The reading should change between Active and Inactive for both directions.

Switch Circuit Test

1. Ignition OFF, disconnect the harness connector at the adjustable pedals switch.
2. Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal C and ground.

⇒	If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the memory seat module.

3. Install a 3A fused jumper wire between the B+ circuit terminal C and the forward switch signal circuit terminal B. Verify the Pedal Forward Switch parameter is Active.

⇒	If not the specified value, test the signal circuit for short to ground or an open/high resistance. If all circuit tests normal, replace the memory seat module.

4. Install a 3A fused jumper wire between the B+ circuit terminal C and the Aft switch signal circuit terminal A. Verify the Pedal Aft Switch parameter is Active.

⇒	If not the specified value, test the signal circuit for short to ground or an open/high resistance. If all circuit tests normal, replace the memory seat module.

5. If all circuits test normal, test or replace the adjustable pedal switch.

1. Ignition OFF, disconnect the harness connector at the adjustable pedal switch.
2. Test for infinite resistance between the signal terminal A and the B+ terminal C with the switch in the open position.

⇒	If not the specified value, replace the adjustable pedal switch.

3. Test for less than 2 ohms between the signal terminal A and the B+ terminal C with the switch in the Aft position.

⇒	If greater than the specified range, replace the adjustable pedal switch.

4. Test for infinite resistance between the signal terminal B and the B+ terminal C with the switch in the open position.

⇒	If not the specified value, replace the adjustable pedal switch.

5. Test for less than 2 ohms of resistance between the signal terminal B and the B+ terminal C with the switch in the Forward position.

⇒	If greater than the specified range, replace the adjustable pedal switch.
