AN650/AK7 (’07-MODEL) 21
“C41” (P2505) ECM/PCM POWER INPUT CIRCUIT MALFUNCTION
"
INSPECTION
Step 1 (When indicating C41:)
1) Turn the ignition switch OFF.
2) Remove the front panel. (#AN650K3 9-8)
3) Check the ECM couplers
1 for loose or poor contacts.
If OK, then measure the ECM input voltage.
4) Disconnect the ECM couplers.
5) Measure the voltage between terminal
W and ground.
$ ECM input voltage: Battery voltage

09900-25009: Needle pointed probe set
' Tester knob indication: Voltage (()
DETECTED CONDITION POSSIBLE CAUSE
C41
(P2505)
No voltage is applied to the ECM,
although the ignition switch is turned
ON.

When using the multi-circuit tester, do not strongly touch the terminal of the ECM coupler with
a needle pointed tester probe to prevent the terminal damage or terminal bend.
