How to Troubleshoot Circuits At the PCM
How to Troubleshoot Circuits at the PGM 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. Remove the cover (A).
3. Lift up the under-hood fuse/relay box (D).
4. Remove the coolant reservoir (E). Disconnect PCM connectors A, B, and C.
NOTE: PCM connectors A, B, and C have symbols (A=Square, B=Triangle, C=Circle) embossed on them for identification.
5. When diagnosis/troubleshooting is done at the PCM connector, use the terminal test port (A) above the terminal you need to check.
6. 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).
