(LD) Response Code 2-1-3

LD. 2-1-3 Set-

Response Code Information
Response code should be posted when the SET button is pressed with the selector switch in the ON position. Fault tracing begins with LD1.

LD1. Response Code Test

If response code 1-3-1 Is posted:
Continue with response code 1-3-2.

If response code 1-3-1 Is not posted:
. Other response codes LD2.


LD2. Other Response Codes

Check whether code 1-1-3, 1-2-3 or 1-3-1 is posted.

If none of the codes is posted:
Fuse check LD3.

If one of the codes is posted:
Selector switch test LD5.


LD3. Fuse Check






Check that fuse 19 in the central electronics module (in-car) is intact.

If fuse is intact:
Test power supply to selector switch LD4.

If fuse is blown:
Check cables between: fuse 19 and selector switch terminal 2, fuse 19 and control module terminal 1B, selector switch terminal 1 and brake valve.

Automatic transmission: brake valve and control module socket terminal 9E, manual transmission: brake valve and clutch valve, manual transmission: clutch valve and control module socket terminal 9E.

Selector switch terminal 3 and control module socket terminal 6E, selector switch terminal 4 and control module socket terminal 8E, selector switch terminal 5 and control module socket terminal 4E, for short circuit to ground, according to QA3. (Q) Other Electrical Fault Tracing


LD4. Test Of Power Supply To Selector Switch






Ignition off.
Disconnect selector switch.
Ignition on.
Using a voltmeter, measure voltage between selector switch connector terminal 2 and ground.Voltmeter should display battery voltage.

If reading is OK:
Selector switch test LD5.

If reading is not OK:
Check the cable between fuse 19 and selector switch terminal 2 for breaks, according to QA2.


LD5. Selector Switch Test






Selector switch connected.
Ignition on.
Selector switch in ON position.Using a voltmeter, measure voltage between selector switch connector terminal 4 and ground.
The voltmeter should display battery voltage when the SET button is pressed and 0 volts when it is not activated.

If readings are OK:
Test of power supply to control module LD7.

If readings are not OK:
Selector switch connector test LD6.


LD6. Selector Switch Connector Test






Ignition off.Service the selector switch connector terminals 2 and 4 for contact resistance and oxidation according to QA6, and for loose connection according to QA5.

Selector switch connected.
Ignition on.
Selector switch in ON position.Using a voltmeter, measure the voltage between the selector switch connector terminal 4 and ground.
Voltmeter should display battery voltage when SET button is pressed.

If reading is OK:
Test of power supply to control module LD7.

If reading is not OK:
Try a new selector switch.


LD7. Test Of Power Supply To Control Module






Control module disconnected.
Selector switch connected.
Ignition on.
Selector switch in ON position.Using a voltmeter, measure the voltage between the control module socket terminal 8E and ground.
Voltmeter should display battery voltage when the SET button is pressed.

If reading is OK:
Control module connector test LD9.

If voltmeter reads about 0 volts when SET button is pressed:
Test cable between selector switch and control module LD8.

If voltmeter displays battery voltage even when SET button is not pressed:
Check cable between selector switch connector terminal 4 and control module socket terminal SE for short circuit to supply, according to QA4.


LD8. Test Of Cable Between Selector Switch And Control Module







Ignition off.
Disconnect control module.
Disconnect selector switch connector.Using an ohmmeter, measure resistance between selector switch connector terminal 4 and control module socket terminal 8E.
The ohmmeter should read about 0 ohm.

If reading is OK:
Connector test LD9.

If reading is not OK:
Check the cable between selector switch connector terminal 4 and control module socket terminal SE for breaks, according to QA2.



LD9. Connector Test

Ignition off. Service selector switch connector terminals 2 and 4 and control module socket terminal 8E for contact resistance and oxidation, according to QA6, and for loose connections, according to QA5..

Connect control module.
Ignition on.
Selector switch in ON position.
Check whether response code 2-1-3 is posted.

If code is posted: The code was not posted because of poor contact in the control module connector.

If code is not posted:
Try a new control module.
