Backers of the so-called "Right To Repair" ballot question are now urging supporters in Massachusetts to vote "yes" on the initiative.
The Right to Repair Committee had initially joined with auto manufacturers to urge voters to skip Question 1 on the November ballot after both sides reached a compromise which was later approved by lawmakers.
The new law requiring car makers provide independent repair shops with access to their diagnostic systems was approved in July, too late to remove it from the ballot.
Last month both sides announced a campaign to tell voters the ballot question was unnecessary.
On Wednesday the Right to Repair Committee decided instead to urge the question's passage.
Committee spokesman Art Kinsman said the group was acknowledging support for the question among consumers and members of the coalition that pushed for the measure.
