Test Re: Re4
Ensure ignition switch is in OFF position. Reconnect interior fuse panel connectors. Disconnect control module connector No. 2. Turn ignition switch to ON position. Check voltage between chassis ground and Blue/Red wire at control module connector No. 2. Check voltage between chassis ground and Black/Yellow wire at control module connector No. 2. If voltage at each wire is greater than 10 volts, but keyless entry system does not operate, go to RE5. If voltages are greater than 10 volts, but alarm does not shut off or locks can be remotely operated with ignition switch in ON position, replace control module. If voltages are 10 volts or less, repair wire(s) in question.
