12. 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 11-313). If symptom/indication goes away, replace the original ECM/PCM.

13. Disconnect ECM/PCM connector A (31P).
14. 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 11-313). If symptom/indication goes away, replace the original ECM/PCM.

15. Remove the glove box.

16. Remove the PGM-FI main relay 1 (A).

17. 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 | - Repair short to power in the wire between the ECM/PCM (A2, A3) and the PGM-FI main relay 1.
NO | - Replace the PGM-FI main relay 1.
