When To Use The Obd-ii Scanner

You may need to reset the anti-theft system on your Jeep Cherokee if the system stops the engine from starting. This often happens after battery disconnection or if the security light stays on.

An OBD-II scanner helps you check and clear security-related trouble codes. It is useful when the anti-theft system causes starting problems or shows warning lights.

The security module controls your Jeep’s anti-theft system. To reset it, you first need to access this module through the OBD-II port under the dashboard.

Connect your OBD-II scanner to this port. Turn the ignition to the ON position, but do not start the engine. This lets the scanner communicate with the security module.

Clearing Fault Codes

Once connected, use the scanner to read any fault codes stored in the security module. These codes help identify the reason the anti-theft system is active.

After reading the codes, you can clear them using the scanner. Clearing these codes often resets the anti-theft system and allows your Jeep to start again.

• Turn ignition to ON without starting
• Connect OBD-II scanner to port
• Read security-related fault codes
• Clear the fault codes with the scanner
• Turn off ignition and restart Jeep
