Measure voltage between ECM/PCM connector terminal E7 and body ground. ECM/PCM CONNECTOR E (31P) Wire side of female terminals Is there battery voltage? YES - Go to step 13. NO - Substitute a known-good ECM/PCM and recheck (see page 11-6). If symptom/indication goes away, replace the original ECM/PCM. Disconnect ECM/PCM connector A (31P). Measure voltage between body ground and ECM/PCM connector terminals A3 and A2 individually. ECM/PCM CONNECTOR A (31P) Wire side of female terminals Is there battery voltage? YES - Go to step 15. NO - Substitute a known-good ECM/PCM and recheck (see page 11-6). If symptom/indication goes away, replace the original ECM/PCM.
