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

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

锟斤拷If 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.

锟斤拷If 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.

锟斤拷If 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

锟斤拷If 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

锟斤拷If 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.

Component Testing

X88/Z88

1. Ignition OFF, disconnect the harness connector at the adjustable pedal switch.

2. Test for infinite resistance between the 12-volt reference terminal 11 and the signal terminals listed below:

* Terminal 10

* Terminal 12

锟斤拷If not the specified value, replace the adjustable pedal switch.

3. Adjustable pedal switch in the FWD position, test for less than 2 ohms between the 12-volt reference terminal 11 and the signal terminal 12.

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

4. Adjustable pedal switch in the RWD position, test for less than 2 ohms between the 12-volt reference terminal 11 and the signal terminal 10.

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

Z75

1. Ignition OFF, disconnect the harness connector at the adjustable pedal switch.

2. Test for infinite resistance between the 12-volt reference terminal 5 and the signal terminals listed below:
