RL V6-3.5L (2007)
-
Camshaft position (CMP) sensor 3P connector
-
Crankshaft position (CKP) sensor A/B 6P connector
-
A/F sensor relay 4P connector
-
Radiator fan control (RFC) relay 4P connector
Does continuity go away when one of the above components is disconnected?
YES - Replace the component that made the short to body ground go away when disconnected. If the item is the PCM, update the PCM if it does
not have the latest software, or substitute a known good PCM, then recheck. If the symptom/indication goes away with a known good PCM,
replace the original PCM. Also replace the No. 8 FI ECU (PCM) (15 A) fuse.
NO - Go to step 29.
29. Disconnect the connectors from these components:
-
PGM-FI main relay 2 (FUEL PUMP)
-
PCM connector A (31P)
-
Injectors
-
Camshaft position (CMP) sensor
-
Crankshaft position (CKP)sensor A/B
-
A/F sensor relay
-
Radiator fan control (RFC) relay
30. Check for continuity between PGM-FI main relay 1 (FI MAIN) 4P connector terminal No. 2 and body ground.
Is there continuity?
YES - Repair short in the wire between PGM-FI main relay 1 (FI MAIN) and each item. Also replace the No. 8 FI ECU (PCM) (15 A) fuse.
NO - Replace PGM-FI main relay 1 (FI MAIN). Also replace the No. 8 FI ECU (PCM) (15 A) fuse.
31. Turn the ignition switch ON (II).
32. Measure voltage between PCM connector terminal D6 and body ground.
Is there battery voltage?
YES - Go to step 33.
NO - Repair open in the wire between the No. 19 FUEL PUMP (15 A) fuse and the PCM (D6).
