I have a problem with the steering wheel controls working on my Pioneer
Last Updated 6 years ago
THE PIONEER ISSUE:
Pioneer head units can have different rest voltage for the steering wheel control input. This can cause the steering wheel controls to function incorrectly. There are Two Solutions available:
- If you have purchased the APPIOA and the steering wheel controls are not functioning correctly, you will need to remove the link between pins 7 & 8 (see Fig 1 below). Link can be removed by de-pinning the block using a small screw driver.Once link is removed from patch lead, disconnect power from steering wheel control module for 30 seconds so the Module will recognise the change to the patch lead.
- If option 1 does not correct the problem, you will need to purchase the APPISOA. The APPISOA will suit both Pioneer and Sony head units. The APPISOA has an in-line PCB which automatically detects which brand unit is being installed and adjusts programming to suit the after market unit .
