Code 26 (Part 2 Of 3):

TEST DESCRIPTION (Cont'd): Numbers below refer to circled numbers on the diagnostic chart.

2. This test will determine which circuit is out of specifications. All circuits EXCEPT "GD16," and "GD15," should be B+ when key "ON," engine not running. The diagnostic test terminal is not grounded.

DIAGNOSTIC AIDS:

Monitor the voltage at each terminal while moving related harness connectors, including PCM harness. If the failure is induced, the voltage will change. This may help locate the intermittent. Check for bent pins at PCM and PCM connector terminals. If code reoccurs with no apparent connector problem, replace PCM.
