82. Check for continuity between ECM/PCM connector terminal A20 and body ground.
Is there continuity?
YES - Repair short in the wire between the ECM/PCM (A20) and the TP sensor, or input shaft (mainshaft) speed sensor.
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.
83. Measure voltage between body ground and ECM/PCM connector terminal E5.
Is there about 5 V?
YES - 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.
NO - Go to step 84.
84. Turn the ignition switch OFF.
85. Disconnect the FTP sensor 3P connector, and measure voltage between body ground and ECM/PCM connector terminal E5with the ignition
switch ON (II).
Is there about 5 V?
YES - Replace the FTP sensor.
NO - Go to step 86.
86. Turn the ignition switch OFF.
87. Jump the SCS line with the HDS.
88. Disconnect the FTP sensor 3P connector.
