Any change in the values indicates a poor connection. Was a connector problem found?
 | ▶ Repair the connector. Go to "Verification of Vehicle Repair" procedure. |
 | ▶ Go to "Power Circuit Inspection" procedure. |
Disconnect the CMPS and PCM connectors and inspect for looseness, poor connection, bending, corrosion, contamination, deterioration or damage. Reconnect the connectors.
Connect the GDS and go to "Current Data".
Monitor CMPS values in Current Data, check and wiggle the harness(es), connector(s), and terminal(s).
Any change in the values indicates a poor connection. Was a connector problem found?
| ▶ Repair the connector. Go to "Verification of Vehicle Repair" procedure. |
| ▶ Go to "Power Circuit Inspection" procedure. |
IG "OFF". Disconnect CMPS #1 connector.
IG "ON".
Measure voltage between power terminal of CMPS #1 harness connector and chassis ground.
