NO - Go to step 77.
77. Turn the ignition switch OFF.
78. Disconnect ECM/PCM connector E (31P).
79. Check for continuity between ECM/PCM connector terminal E29 and body ground.
Is there continuity?
YES - Repair short in the wire between the DLC and the ECM/PCM (E29).
NO - Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM, then recheck. If the
symptom/indication goes away with a known-good ECM/PCM, replace the original ECM/PCM.
80. Turn the ignition switch OFF.
81. Disconnect ECM/PCM connector E (31P).
82. Turn the ignition switch ON (II).
Is the MIL on?
YES - Repair short in the wire between the gauge assembly and the ECM/PCM (E31). If the wires are OK, replace the gauge assembly.
NO - Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM, then recheck. If the
symptom/indication goes away with a known-good ECM/PCM, replace the original ECM/PCM.
