------------------------
FAULT FOUND - Checking the response code
-------------------------------------------------
Checking the response code
- Ignition on.
- Activate the Scan Tool (ST) in MODE 2.
- Move the ON/OFF switch to the ON position.
- Activate the SET- switch
- Check that the SET+ function is OK by checking that response code 1-3-1 is returned.
Is response code 1-3-1 returned?
- 1. Yes, response code 1-3-1 is returned.
- 2. No, response code 1-3-1 is not returned.
- 3. No, response code 3-1-1 is returned instead.
Select one of the above options.
1 - No Fault Found
2 - Checking other response codes
3 - Checking response code 3-1-1
-------------------------------------------------
Checking response code 3-1-1
A response code is transmitted when the control module receives several signals from the same component or wiring circuit within 8 milliseconds. The cause of the fault may be loose connections in the terminals or a defective system component.
Continue - Checking other response codes
-------------------------------------------------
Checking other response codes
- Ignition on.
- Activate the Scan Tool (ST) in MODE 2.
- Move the switch from ON to OFF or from OFF to ON.
- Check that the ON/OFF switch is OK by checking that response code 1-1-3 is returned.
Is response code 1-1-3 returned?
Yes - Checking the selector switch

- 1. The value is OK.
- 2. The voltmeter reads 0 V.
- 3. The voltmeter reads battery voltage when the SET+ switch is not activated.
Select one of the above options.
1 - Checking the control module connectors
2 - Checking the cable between the selector switch and the control module
3 - Checking for a short-circuit
-------------------------------------------------
Checking for a short-circuit
- Ignition off.
- Check the cable between selector switch connector terminal #3 and control module connector terminal #6 for a short-circuit to supply voltage according to Checking wiring and terminals. Permanent fault Checking Wiring And Terminals. Permanent Fault.
