Test Description

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2004 Oldsmobile Bravada, 2004 GMC Envoy XUV, 2004 GMC Envoy XL, 2004 GMC Envoy, and 2004 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.

The numbers below refer to the step numbers on the diagnostic table.

  1. 3:  Tests for the proper operation of the circuit in the low voltage range.
  2. 4:  Tests for the proper operation of the circuit in the high voltage range. If the fuse in the jumper opens if you perform this test, the signal circuit is short to ground.
  3. 5:  Tests for a short to voltage in the 5-volt reference circuit.

  1. Install a scan tool.
  2. With a scan tool, observe the brake pedal position sensor parameter in the seat module Adjustable Pedal data list.
Is the position sensor parameter within the specified range?		 0.39-4.58 V Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems Go to Step 3 
3 
  1. Disconnect the position sensor connector.
  2. With a scan tool, observe the position sensor parameter.
Is the position sensor parameter less than the specified value?		 0.39 V Go to Step 4  Go to Step 8 
4 
  1. Connect a 3-amp fused jumper wire between the 5-volt reference circuit terminal and the signal circuit terminal in the position sensor harness connector.
  2. With a scan tool, observe the position sensor parameter.
Is the position sensor parameter greater than the specified value?		 4.58 V Go to Step 5  Go to Step 7 
5 
  1. Disconnect the fused jumper wire.
  2. Measure the voltage between the 5-volt reference circuit terminal and the low reference circuit terminal in the position sensor harness connector.
Is the voltage measure greater than the specified value?		 5.0 V Go to Step 6  Go to Step 10 
6 Test the 5-volt reference circuit for a short to voltage. Refer to Circuit Testing and to Wiring Repairs in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 15  Go to Step 12 
7 Test the 5-volt reference circuit for one of the following conditions:
  • A short to ground
  • A high resistance
  • An open

Refer to Circuit Testing and to Wiring Repairs in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 15  Go to Step 9 
8 Test the signal circuit of the position sensor for a short to voltage. Refer to Circuit Testing and to Wiring Repairs in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 15  Go to Step 12 
9 Test the signal circuit of the position sensor for one of the following conditions:
  • A short to ground
  • A high resistance
  • An open

Refer to Circuit Testing and to Wiring Repairs in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 15  Go to Step 12 
10 Test the low reference circuit of the position sensor for an open or high resistance. Refer to Circuit Testing and to Wiring Repairs in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 15  Go to Step 11 
11 Inspect for poor connections at the brake pedal position sensor. Refer to Testing for Intermittent Conditions and Poor Connections and to Connector Repairs in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 15  Go to Step 13 
12 Inspect for poor connections at the driver seat module. Refer to Testing for Intermittent Conditions and Poor Connections and to Connector Repairs in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 15  Go to Step 14 
13 Replace the brake pedal position sensor. Refer to Brake Pedal Position Sensor Replacement  .
Did you complete the replacement?		 - Go to Step 15  -
14 Replace the driver seat module. Refer to Memory Seat Control Module Replacement in Seats.
Did you complete the replacement?		 - Go to Step 15  -
