* The DTC becomes history when the conditions for setting the DTC are no longer present.
* The history DTC clears after 100 malfunction-free ignition cycles.

Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at the adjustable pedal motor.
2. Ignition OFF, test for less than 10 ohm between the low reference circuit terminal 3 and ground.
锟斤拷 If greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the MSM.
3. Ignition ON, test for 4.8-5.2 volts between the 5-volt reference circuit terminal 1 and ground.
锟斤拷 If less than the specified range, test the 5-volt reference circuit for a short to ground or an open/high resistance. If the circuit tests normal,
replace the MSM.
锟斤拷 If greater than the specified range, test the 5-volt reference circuit for a short to voltage. If the circuit tests normal, replace the MSM.
4. Verify the scan tool Pedal Position parameter is less than 0.45 volt.
锟斤拷 If greater than the specified range, test the signal circuit terminal 2 for a short to voltage. If the circuit tests normal, replace the MSM.
5. Install a 3A fused jumper wire between the signal circuit terminal 2 and the 5-volt reference circuit terminal 1. Verify the scan tool Pedal
Position parameter is greater than 4.55 volts.
锟斤拷 If less than the specified range, test the signal circuit for short to ground or an open/high resistance. If the circuit tests normal, replace the
MSM.
6. If all circuits test normal, test or replace the adjustable pedal motor.
