Power Circuits (Q45)
- Turn ignition switch to RUN position. Using a DVOM, check for battery voltage between ground and PCM terminals No. 56, 130 and 131. See Fig 2
. If battery voltage is present at all terminals, go to next step. If battery voltage is not present at all terminals, check fusible link, fuse "G" and wiring. Repair as necessary.
- Turn ignition switch to OFF position. Using a DVOM, check for battery voltage between ground and PCM terminal No. 78 (power back-up). If battery voltage is present, power circuits are okay at this time. If battery voltage is not present, check for overheated relays, fusible links and wiring.
