POWERTRAIN CONTROL MODULE (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.

Using 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 Nm {80 - 110 kgf-m, 69.5 - 95.4 in-lbf}

5. Connect the negative battery cable.
6. Measure the voltage at each terminal.
7. If any incorrect voltage is detected, check related systems, wiring harnesses and connectors referring to the possible malfunction in the terminal voltage list.

Using the SST (WDS or equivalent tester)

1. In the passenger compartment, connect the SST to the data link connector.

CAUTION: The "PID/DATA MONITOR AND RECORD" function is to monitor the the calculation value of the input/output signals in the PCM. Deviation in the value does not always indicate malfunction in the related devices. For inspection of the input/output signals other than in the link monitor table, check voltage at the applicable PCM terminal by using the SST (104 Pin Breakout Box).

2. Carry out inspection referring to PID/DATA MONITOR table.
3. If normal output signal cannot be detected when all input signals are normal, replace the PCM.
