  3. Remove the under-hood multi-relay box from the under-hood fuse/relay box.
  4. Remove the screws (A) from the alternator and battery cable terminals.
  5. Remove the two mounting bolts (B) from the under-hood fuse/relay box.
  6. Remove the under cover from the under-hood fuse/ relay box.
  7. Disconnect the connectors from the under-hood fuse/relay box.
  8. If replacing the fuse/relay box, carefully remove the relays by prying under the base of the relay. NOTE: Do not use pliers, they will damage the relays.

Installation

  1. Install the relays and connect the connectors to the under-hood fuse/relay box, then install the under-hood fuse/relay box in the reverse order of removal.
  2. Install the removed parts in the reverse order of removal.
  3. Connect the positive cable to the battery, then connect negative cable to the battery.
  4. Do the ECM/PCM idle learn procedure (see «ECM/PCM IDLE LEARN PROCEDURE»(/acura/tsx/i-2003-2008/remont/engine-control-systems/#idle-control-system__ecmpcm-idle-learn-procedure) ).
  5. Do the power window control unit reset procedure (see «RESETTING THE POWER WINDOW»(/acura/tsx/i-2003-2008/remont/windows/#power-window-system__resetting-the-power-window) ).
  6. Enter the anti-theft codes for the audio system and navigation system (if equipped), then enter the audio presets. Set the clock (on vehicles without navigation).
  7. Confirm that all systems work properly.

  1. Clear the DTCs using the Honda Diagnostic System (HDS).
  2. Cycle the ignition switch OFF then ON.
  3. Check for DTCs by selecting the DTCs MENU (DTCs) from the HDS. Is DTC B1055, B1056, B1057, B1058, B1059, B1060, B1061, B1062 and/or B1063 indicated? YES -Go to step 4. NO -Intermittent failure, the B-CAN communication line is OK at this time.
  4. Check for DTCs other than those listed. Are any other DTCs present? YES -Go to step 5. NO -Perform Relay Control Module Input Test (see «RELAY CONTROL MODULE INPUT TEST»(/acura/tsx/i-2003-2008/remont/communication-devices/#multiplex-integrated-control-system) ).
  5. Find the chart that contains at least one retrieved DTC in column A and one retrieved DTC in column B. Perform the input test for the ECU listed in that chart. If no DTC from column B is found then continue to Relay Control Module input test.
