Replaced transmission and battery in 02 CRV. Used memory saver in OBD2 connector when changing battery. After job was done radio is totally dead - no error or code message(radio is one with built in cd changer). The only thing working is the lighting that comes on with the inst. Panel lights. Also the cruise control is not working. There are no burnt fuses. I tested at the radio connector and have 12.01V on wh/red wire and 11.97V on yellow/red wire with key on.12.34V on wh/red wire with key off. Showing ground on black wire. Testing at cruise control switch have ground on black wire, 11.9V on green/yellow wire and 12V on lt. Green wire when the button is pushed on. Light to indicate cruise is on does not come on when the button is pushed and cruise control does not work. Is there a common module involved here? Any help would be appreciated.

When removing the transmission, the battery had to be disconnected, was the memory saver used? What is the rationale for using it?

Recheck the installation of components removed while the transmission was replaced. Ensure the cruise control components are correctly installed.

Remove the back-up fuse (radio) fuse to reset the radio and key in the radio code. If you wish to keep the memory as was the purpose of the memory saver, remove the radio and unplug its harness to reset the radio.

Radio now working. Answer was not helpful-had already covered the basics and had stated that a memory saver was used. This was a strange problem, the radio was totally dead and nothing would reset it. Tried removing the back-up fuse - even disconnected the battery over-night and still nothing. I put the car out and locked it with the remote, unlocked it the next day and the radio was working - just had to enter the code. Radio now working but volume control not working properly - could here sound but unable to turn it up. Got in the car the next day and radio worked perfectly - volume control normal. Very weird - the only thing I can think of is that it was related to the security system and locking and unlocking the doors reset the radio. As for the volume control I don't know how but it seems to have reset itself overnight. However still no cruise control. Thanks for taking an interest in my question - I may have another down the road.

The only connection between the radio and security system is the Multiplex Control Unit.

The chart shows possible causes for the cruise control not working.

CLUTCH PEDAL POSITION SWITCH TEST
1. Disconnect the 2P connector from the clutch pedal position switch (A).

Fig. 24: Disconnecting 2-Pin Connector From Clutch Pedal Position Switch

2. Remove the clutch pedal position switch.

3. Check for continuity between the terminals according to the table.

� If the continuity is not as specified, replace the clutch pedal position switch.

� If OK, install the clutch pedal position switch and adjust the pedal height.
