Test H: Can't Adjust Pedals: Testing

NOTE: Adjustable pedals are disabled when the vehicle is in reverse or when the speed control is activated.
  1. Check whether vehicle is in reverse and whether speed control is activated. Is the vehicle in Reverse or is Speed Control activated. If yes, correct as necessary. Perform ADJUSTABLE PEDAL VERIFICATION TEST VER 1  . If no, go to next step.
  2. With the DRBIII(R), erase DTC's. With the DRBIII(R), read DTC's. With the DRBIII(R) in Inputs/Outputs, read the In-Plant mode state. Are any DTCs active or is the Adjustable Pedals Module (APM) in the In-Plant mode? If yes, go to appropriate DTC test or disable In-Plant test mode. Perform ADJUSTABLE PEDAL VERIFICATION TEST VER 1  . If no, go to next step.
  3. Turn the ignition off. Disconnect the APM harness connector. Connect a jumper wire between the Battery Feed circuit and ground. Operate the adjustable pedals switch to the AFT and FWD positions. Using a 12-volt test light connected to 12-volts, check the AFT and FWD circuits. Does the test light illuminate brightly in each switch position? If yes, go to next step. If no, go to step  6 .
  4. Turn the ignition off. Disconnect the adjustable pedals motor/sensor harness connector. Operate the adjustable pedals switch to the FWD position. On the APM side of the connector, using a 12-volt test light connected to ground, check the FWD circuit. On the APM side of the connector, using a 12-volt test light connected to 12-volts, check the AFT circuit. Does the test light illuminate brightly at each pin? If yes, repair any wiring concerns. If no concerns are found, replace the adjustable pedals motor/sensor assembly. See ADJUSTABLE PEDAL ASSEMBLY  under REMOVAL & INSTALLATION. Perform ADJUSTABLE PEDAL VERIFICATION TEST VER 1  . If no, go to next step.
  5. Turn the ignition off. Disconnect the APM harness connector. Disconnect the adjustable pedals motor/sensor connector. Check the FWD and AFT circuits for short to battery, to ground, to each other and for an open. Is the FWD or AFT circuit shorted or open? If yes, repair the adjustable pedals motor FWD or AFT circuit short or open as necessary. Perform ADJUSTABLE PEDAL VERIFICATION TEST VER 1  . If no, replace and program the adjustable pedals module. See ADJUSTABLE PEDAL MODULE  under REMOVAL & INSTALLATION. Perform ADJUSTABLE PEDAL VERIFICATION TEST VER 1  .
  6. Turn the ignition off. Disconnect the APM harness connector. Disconnect the adjustable pedals switch connector. Measure the resistance of the battery feed circuit. Is the resistance above 5.0 ohms? If yes, repair the battery feed circuit for an open. Perform ADJUSTABLE PEDAL VERIFICATION TEST VER 1  . If no, replace the adjustable pedals switch. See ADJUSTABLE PEDAL SWITCH  under REMOVAL & INSTALLATION. Perform ADJUSTABLE PEDAL VERIFICATION TEST VER 1  .
