To replace the engine light bulb in a 2001 Isuzu Rodeo, first, disconnect the negative battery terminal to ensure safety. Remove the instrument cluster by unscrewing the screws and gently pulling it out. Locate the bulb holder for the engine light, twist it counterclockwise to remove it, then replace the old bulb with a new one and reassemble everything in reverse order. Finally, reconnect the battery and check to ensure the light works properly.

You cannot replace the clock 'light' on an older CR-V since there is no bulb. It is an L.C.D. (liquid crystal diode) unit which, if it fails, must be replaced.
The check engine light for the 2001 Isuzu Rodeo often comes on because of a sensor that is damaged or malfunctioning. The most common sensor is an oxygen sensor and when reset, this often allows the light to be reset.

It is called a "clock spring" take it to your dealer they have to replace it free of charge, safety recall.
To repair the clock on a 2001 Toyota 4Runner, first check the fuse associated with the clock; if it's blown, replace it. If the fuse is fine, remove the clock assembly by gently prying it out of the dashboard. Inspect the connections for any loose wires, and if necessary, replace the entire clock unit. Reinstall the assembly and test the clock to ensure it's functioning properly.
I had same problem with my 2001 Isuzu rodeo sport with 53K miles.......and just put a new battery in and presto, no more abs light.....I think if your battery is weak (does the car have any problems starting and is electrical good?), it will trigger the abs light.....it did on mine.
