PCM INSPECTION

CAUTION: The PCM terminal voltages vary with change in measuring conditions and vehicle conditions. Always carry out a total inspection of the Input systems, output systems, and PCM to determine the cause of trouble. Otherwise, a wrong diagnosis will be made.

PCM Inspection Using the SST (104 Pin Breakout Box)
1. Disconnect the negative battery cable.




2. Disconnect the PCM connector.
3. Connect the SST (104 Pin Breakout Box) to the PCM as shown.
4. Tighten the connector bolt.

Tightening torque
7.9 - 10.7 N.m {80 - 110 kgf.m, 69.5 - 95.4 in.lbf}

5. Connect the negative battery cable.
6. Measure the voltage at each terminal.
- If any incorrect voltage is detected, inspect the related system(s), wiring harnesses and connector(s) referring to the Action column in the terminal voltage table.
