Test point 18

Pot. mirror right horizontal

Fault code 20

This fault is stored in the following cases:

1. There is an open circuit in the wire to the pot right rearview mirror.

2. The potentiometer is faulty,

3. The control module is faulty. Elimination

Replace support with transmission.

Actuate switch for memory seat adjustment,

The text in the fault memory changes from present to not present if the cause of the fault has really been eliminated.

If the fault is no longer present, erase the fault memory

If the fault is still present, there is a fault in the wire.

For a fault in the wire, proceed as described below:

Disconnect mirror plug from the control module.

Disconnect support with transmission plug,

Use an ohmmeter to check for open circuit on the support plug Pin 5 and the mirror plug on the control module Pin 11.

Use an ohmmeter to check for open circuit on the support plug Pin 7 and the mirror plug on the control module Pin 4.

Use an ohmmeter to check for continuity on the support plug

If no fault is detected in the wire, replace the control module,

Test point 19

Pot. mirror riight horizontal

Fault code 21

This fault is stored in the following cases:

1. There is a short circuit in the wire to the pot. right rearview mirror.

2. The potentiometer is faulty.

3. The control module is faulty. Elimination:

1. Replace support with transmission.

2. Actuate switch for memory seat adjustment.

The text in the fault memory changes from present to not present if the cause of the fault has really been eliminated.

If the fault is still present, there is a fault in the wire. For a fault in the wire, proceed as described below:

Disconnect plug at support with transmission.

Disconnect mirror plug from the control module.

Use an ohmmeter to check for short circuit on the support plug Pin 5, wire colour yellow, and Pin 7, wire colour pink.

If no short circuit is detected:

Use an ohmmeter to check for open circuit on the support plug Pin 3 and the mirror plug on the control module Pin 5

If the fault is still present, replace control module.

Test point 20

Actuate switch for memory seat adjustment

The text in the fault memory changes from present to not present if the cause of the fault has really been eliminated.

If the fault is no longer present, erase the fault memory.

If the fault is still present, there is a fault in the wire,

For a fault in the wire, proceed as described below:

Disconnect mirror plug from the control module.

Disconnect plug at support with transmission.

Use an ohmmeter to check for open circuit on the support plug Pin 5 and the mirror plug on the control module Pin 11

Use an ohmmeter to check for open circuit on the support plug Pin 7 and the mirror plug on the control module Pin 4.

Use an ohmmeter to check for continuity on the support plug

If no fault is detected in the wire, replace the control module,

Test point 21

Pot. mirror right vertical

Fault code 23

This fault is stored in the following cases:

1. There is a short circuit in the wire to the pot. right rearview mirror.

2. The potentiometer is faulty.

3. The control module is faulty. Elimination:

Replace support with transmission.

Actuate switch for memory seat adjustment.

The text in the fault memory changes from present to not present if the cause of the fault has really been eliminated.

If the fault is still present, there is a fault in the wire.

For a fault in the wire, proceed as described below:

Disconnect plug at support with transmission.

Disconnect mirror plug from the control module.

Use an ohmmeter to check for short circuit on the support plug Pin 1, wire colour grey, and Pin 7, wire colour pink. No continuity must be measured.' If no short circuit is detected:

Use an ohmmeter to check for open circuit on the support plug Pin 3 and the mirror plug on the control module Pin 5

Use an ohmmeter to check for continuity on the support plug

If no fault is detected in the wire but the fault is still present,
