DTC B0282: Right Temperature Actuator

WARNING: This page is about a different car, the 2002 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: The numbers below refer to the step numbers of the diagnostic procedure.
  1. - Tests for the proper operation of the circuit in the high voltage range.
  2. - Tests for the proper operation of the circuit in the low voltage range. If the fuse in the jumper opens when you perform this test, the signal circuit is shorted to voltage.
  3. - Tests for a short to ground in the 5 volt reference circuit.
  1. Perform diagnostic system check. See DIAGNOSTIC SYSTEM CHECK  under SELF-DIAGNOSTIC SYSTEM. After performing system check, go to next step.
  2. Connect scan tool. Turn ignition on. Using scan tool, observe RIGHT TEMP DR ACTUAL parameter in INSTRUMENT PANEL MODULE HVAC DOOR POSITIONS data list. If scan tool indicates RIGHT TEMP DR ACTUAL parameter is 0.09-4.9 volts, inspect wiring and connectors for intermittent loose wires and/or poor connections. Also check for a damaged or broken right air temperature door or actuator. Repair as necessary and go to step  9. If scan tool indicates RIGHT TEMP DR ACTUAL parameter is not between 0.09-4.9 volts, go to next step.
  3. Use scan tool to change RIGHT TEMP DOOR POSITION from HOT to COLD. Using scan tool, observe RIGHT TEMP DR ACTUAL parameter in INSTRUMENT PANEL MODULE HVAC DOOR POSITIONS data list. If scan tool indicates RIGHT TEMP DR ACTUAL parameter in INSTRUMENT PANEL changes when RIGHT TEMP DR is moved from hot to cold, inspect right air temperature door actuator for a condition allowing excessive travel, if air temperature door actuator is okay, check for loose wires and/or poor connections at right air actuator. Repair as needed and go to step  9. If wiring and connectors are okay, replace right air temperature door actuator. See AIR TEMPERATURE DOOR ACTUATORS  under REMOVAL & INSTALLATION. Go to step  9. If scan tool indicates RIGHT TEMP DR ACTUAL parameter in INSTRUMENT PANEL does not change when RIGHT TEMP DR is moved from hot to cold, go to next step.
  4. Turn ignition off. Disconnect right air temperature door actuator. Turn ignition on. Using scan tool, observe RIGHT TEMP DR ACTUAL parameter. If scan tool indicates RIGHT TEMP DR ACTUAL parameter is more than 4.9 volts, go to next step. If RIGHT TEMP DR ACTUAL parameter is 4.9 volts or less, check continuity between ground and terminal No. 9 (Dark Blue wire) of right air temperature door actuator harness connector. See Figure. If continuity exists, repair short to ground in Dark Blue wire between right air temperature door actuator and terminal A6 of Instrument Panel Module (IPM). Go to step  9. If continuity does not exist, go to next step.
  5. Turn ignition off. Connect 3-amp. fused jumper wire between terminals No. 6 (White/Black wire) and No. 7 (Yellow wire) of right air temperature door actuator harness connector. See Figure. Turn ignition on. Using scan tool, observe RIGHT TEMP DR ACTUAL parameter. If scan tool indicates RIGHT TEMP DR ACTUAL parameter is 0.09 volts or less, go to next step. If scan tool indicates RIGHT TEMP DR ACTUAL parameter is more than 0.09 volts, check for voltage between ground and terminal No. 6 (White/Black wire) of right air temperature door actuator harness connector. If voltage exists, repair short to voltage in White/Black wire between right air temperature door actuator and terminal A12 of IPM. Go to step  9. If voltage does not exist, check continuity in Yellow wire between terminal No. 7 of right air temperature door actuator and terminal A7 of IPM. See Figure and Figure . If continuity exists, check for loose wires and/or poor connections at IPM. If wiring and connections are okay, replace IPM. See INSTRUMENT PANEL MODULE (IPM)  under REMOVAL & INSTALLATION. Go to step  9.
  6. Turn ignition off. Disconnect fused jumper wire. Reconnect jumper wire between terminal No. 6 (White/Black wire) and No. 9 (Dark Blue wire) of right air temperature door actuator harness connector. See Figure. Turn ignition on. Using scan tool, observe RIGHT TEMP DR ACTUAL parameter. If scan tool indicates RIGHT TEMP DR ACTUAL parameter is more than 4.9 volts, go to step  8. If scan tool indicates RIGHT TEMP DR ACTUAL parameter is 4.9 volts or less, go to next step.
  7. Turn ignition off. Check continuity between ground and terminal No. 9 (Dark Blue wire) of right air temperature door actuator harness connector. See Figure. If continuity exists, repair short to ground in Dark Blue wire between right air temperature door actuator and terminal A6 of IPM. Go to step  9. If continuity does not exist, check for loose wires and/or poor connections at IPM. If wiring and connections are okay, replace IPM. See INSTRUMENT PANEL MODULE (IPM)  under REMOVAL & INSTALLATION. Go to step  9.
  8. Turn ignition off. Check for voltage between ground and terminal No. 9 (Dark Blue wire) of right air temperature door actuator harness connector. See Figure. If voltage exists, repair short to voltage in Dark Blue wire between right air temperature door actuator and terminal A6 of IPM. See Figure. Go to step  9. If voltage does not exist, check for loose wires and/or poor connections at right air temperature door actuator. If wiring and connections are okay, replace right air temperature door actuator. See AIR TEMPERATURE DOOR ACTUATORS  under REMOVAL & INSTALLATION. Go step  9.
  9. Use scan tool to clear DTCs. Operate vehicle and verify that DTCs do not reset. If DTCs reset, return to step  2. If DTCs do not reset, system is okay.
