1. Check sensor.
(a) Connect MSD (WP 0005 00).
(b) Disconnect wiring harness from brake
1. If diagnostic code changed from CID
pedal position sensor (WP 0075 00).
0737 FMI 04 to CID 0737 FMI 03,
replace brake pedal position sensor (WP
0075 00).
2. If diagnostic code remains, go to Test 2.
2. Check wiring harness.
(a) Sensor remains disconnected from
wiring harness.
(b) Turn battery disconnect and engine
start switches to OFF position (TM 5-
3805-291-10).
(c) Disconnect wiring harness connectors
from powertrain ECM (WP 0063 00).
(d) At wiring harness connector for sensor, 1. If resistance is greater than 5,000 Ohms,
measure resistance between signal
exit this procedure and repeat this
contact 3 (wire G746-WH) and frame
procedure. If failure is not found,
ground.
replace powertrain ECM (WP 0063 00).
2. If resistance is less than 5,000 Ohms,
there is a short between frame ground
and signal circuit in wiring harness.
Replace wiring harness in question (WP
0195 00 thru WP 0201 00).
