General Information
- Trouble codes can be displayed by the malfunction indicator lamp (MIL) with the data link connector (DLC) terminals jumped Image 1
- Honda Passport uses a different trouble code system than other Hondas
Accessing Trouble Codes
- Ensure ignition switched OFF
- Jump data link connector (DLC) terminals 1 and 3 Image 1
- Switch ignition ON. Do NOT start engine
- MIL should flash
- Trouble code 12 will be displayed three times
- Each trouble code will be displayed three times
- If no trouble codes are stored, code 12 will continue to be displayed
- Count MIL flashes and compare with trouble code table
- Short flashes indicate the ‘tens’ and ‘units’ of the trouble code Image 2
- A 0.4 second pause separates each flash. A 1.2 second pause separates the ‘tens’ and ‘units’. A 3.2 second pause separates each trouble code.
- For example: Trouble code 23 displayed Image 2
- Count MIL flashes and compare with trouble code table below
- Switch ignition OFF
- Remove jump lead
Clearing Trouble Codes
- After the faults have been rectified, erase the trouble codes as follows:
- Ensure ignition switched OFF
- Disconnect battery ground cable for 30 seconds.
- Reconnect battery ground cable
- Repeat accessing procedure to ensure no data remains in ECM fault memory
