Circuit/System Verification

Ignition ON, observe the scan tool Pedal Forward Switch and Pedal Aft Switch parameters while cycling the adjustable pedal switch between the

FWD and RWD position. The appropriate parameter should change between Active and Inactive as commanded.

Circuit/System Testing

1. Disconnect the harness connector at the adjustable pedal switch.

2. Ignition ON, test for 11.8-12.2 volts between the appropriate 12-volt reference circuit listed below and ground:

* X88/Z88 - terminal 11

* Z75 - terminal 5

瀚慖f greater than the specified range, test the 12-volt reference circuit for a short to voltage. If the circuit tests normal, replace the MSM.

瀚慖f less than the specified range, test the 12-volt reference circuit for a short to ground or an open/high resistance. If the circuit tests

normal, replace the MSM.

3. Verify the scan tool Pedal Forward Switch parameter is Inactive.

瀚慖f not the specified value, test the appropriate signal circuit terminal listed below for a short to voltage. If the circuit tests normal, replace

the MSM.

* X88/Z88 - terminal 12

* Z75 - terminal 6

4. Verify the scan tool Pedal Aft Switch parameter is Inactive.

瀚慖f not the specified value, test the appropriate signal circuit terminal listed below for a short to voltage. If the circuit tests normal, replace

the MSM.

* X88/Z88 - terminal 10

* Z75 - terminal 4

5. Install a 3A fused jumper wire between the appropriate signal circuit terminal listed below and B+. The scan tool Pedal Forward Switch

parameter should be Active.

* X88/Z88 - terminal 12

* Z75 - terminal 6

瀚慖f not the specified value, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the

MSM.

6. Install a 3A fused jumper wire between the appropriate signal circuit terminal listed below and B+. The scan tool Pedal Aft Switch parameter

should be Active.

* X88/Z88 - terminal 10

* Z75 - terminal 4

瀚慖f not the specified value, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the

MSM.

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