DTC P0630: VIN Not Programmed or Mismatch Honda Odyssey III

Testing & Diagnostics 3 illustrations ~1235 words

Note. This DTC is stored only when the PCM does not have the VIN information of the vehicle. Use the HDS to input the missing VIN information.

  1. Turn the ignition switch ON (II).
  2. Check the VIN with the HDS. Does the HDS show the vehicle's VIN? YES - Go to step 5 . NO - Go to step 3.
  3. Input the VIN to the PCM with the HDS. Does the screen show COMPLETE? YES - Go to step 5 . NO - Go to step 4.
  4. Check for DTCs with the HDS. Is DTC P0603 indicated? YES - Go to the DTC P0603 troubleshooting. NO - Update the PCM if it does not have the latest software, or substitute a known-good PCM (see «PCM UPDATING AND SUBSTITUTION FOR TESTING»(ref-220945-S16531944742006022100000) ), then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM (see «PCM REPLACEMENT»(ref-220946-S32339521312006022100000) ).
  5. Clear the DTC with the HDS.
  6. Turn the ignition switch OFF.
  7. Turn the ignition switch ON (II), and wait 5 seconds.
  8. Check for Temporary DTCs or DTCs with the HDS. Are any Temporary DTCs or DTCs indicated? YES - If DTC P0630 is indicated, update the PCM if it does not have the latest software, or substitute a known-good PCM (see «PCM UPDATING AND SUBSTITUTION FOR TESTING»(ref-220945-S16531944742006022100000) ), then recheck. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting. NO - Intermittent failure, system is OK at this time.
