The following test procedure may create other diagnostic codes. Ignore
these created diagnostic codes and clear the diagnostic codes when the
original diagnostic code is corrected. Ensure diagnostic code CID 0737
FMI 03 is active before performing this procedure.
1. Check voltage at sensor.
(a) Turn battery disconnect and engine
start switches to ON position (TM 5-
(b) Disconnect brake pedal position sensor
from wiring harness (WP 0075 00).
(c) At wiring harness connector for sensor, 1. If voltage is approximately battery
voltage, go to Test 4.
measure voltage between contact 1
(wire 126-PK) and contact 2 (wire
2. If voltage is not approximately battery
voltage, go to Test 2.
2. Check for an open circuit in supply circuit.
(a) Engine start and battery disconnect
switches remain in ON position (TM 5-
(b) Sensor remains disconnected from
