Engine speed signal, checking

If a malfunction of the RPM display at tachometer
is detected, signal at the tachometer must be
checked.

- Connect VAS5051 tester or VAG1551 scan tool
Page 01
-241
.

- Read Measuring Value Block Page 01
-
114
.

- Select display group number 001 and perform a
road test.
If the speed appears on the VAG1551 Scan Tool
display but not via the speedometer in instrument
cluster, the instrument cluster is faulty and must
be replaced.
If no speed is indicated on the VAG1551 Scan
Tool display either, the signal must be checked
at multi-function connection at instrument
cluster.

- Remove instrument cluster Page 90

- Connect VAG1598 tester with VAG1598/25
adapter to the blue 32-pin connector.

- Perform an acoustic continuity check of the
sensor and wire using the VAG1526 multimeter
between terminal 28 and socket 9 (load Ground
(GND))
Test
The beep signal of the resistance tester must
switch on and off several times while the vehicle
is rolled slightly forward and backward (approx.
1m)
If the test is not OK, the wire connection to speed
sender must be checked.

- Check wire connection according to wiring
diagram.

Electrical Wiring Diagrams, Troubleshooting &
Component Locations If the wire connection is OK, the speed sender
must be replaced.
