Circuit/System Testing
- Disconnect the left instrument panel (I/P) junction block connector C2.
- Verify that a test lamp illuminates when connected from the park enable relay supply circuit terminal E2 in the harness connector to ground.
- If the test lamp does not illuminate repair the park enable relay supply circuit for an open or short to ground. If the circuit tests normal and the EAP fuse #73 is open, test the following circuits for a short to ground:
- Switch supply circuit
- Switch signal circuits
- Motor control circuits
- Disconnect the left I/P junction block connector C1.
- Connect a DMM from the adjustable pedal switch supply circuit terminal C4 to the forward switch signal circuit in connector C2 terminal G1.
- Verify less than 1 ohm of resistance while pressing the adjustable pedal forward switch.
- If greater than 1 ohm of resistance test the switch supply and signal circuits for an open or high resistance. If the circuits test normal replace the adjustable pedal switch.
- Connect a DMM from the adjustable pedal switch supply circuit terminal C4 to the rearward switch signal circuit in connector C2 terminal E1.
- Verify less than 1 ohm of resistance while pressing the adjustable pedal rearward switch.
- If greater than 1 ohm of resistance test the switch signal circuit for an open or high resistance. If the circuit tests normal replace the adjustable pedal switch.
- Connect the I/P junction block connectors.
- Disconnect the adjustable pedal motor connector and connect a test lamp across the control circuit terminals in the harness connector.
- Verify that the test lamp illuminates when the adjustable pedal switch is pressed in both directions.
- If the test lamp does not illuminate while the switch is pressed in both directions, test the control circuits for an open or high resistance. If the control circuits test normal replace the left I/P junction block.
- If the circuit tests are normal replace the adjustable pedal motor.
