How to Troubleshoot Circuits at the PCM Connectors
NOTE: The PCM overwrites data and monitors the EVAP system for up to 30 minutes after the ignition switch is turned OFF. Jumping the SCS line
after turning the ignition switch OFF cancels this function. Disconnecting the PCM during this function, without jumping the SCS line first, can damage
the PCM.
1. Jump the SCS line with the HDS.
2. Disconnect the PCM connectors A, B, and C.
3. When diagnosis/troubleshooting is done at the PCM connector, use the terminal test port (A) above the terminal you need to check.
4. Connect one side of the patch cord (A) terminals to a commercially available digital multimeter (B), and connect the other side of the patch cord
terminals to a commercially available banana jack (Pomona Electronics Tool No. 3563 or equivalent) (C).
5. Gently contact the pin probe (male) at the terminal test port from the terminal side. Do not force the tips into the terminals.
