Test 4, Check Pip Out Continuity
With key off, disconnect ECA. With an ohmmeter, measure resistance between Pin No. 56 of the ECA vehicle harness connector and J31 (PIP EEC). See Fig 1 . If resistance is less than 5 ohms, refer to the TESTS W/CODES article, PINPOINT TEST A in this section. If resistance is more than 5 ohms, service open circuit, reconnect ECA and check for fault codes. See TESTS W/CODES article.
