Measure between terminal A (minus) and B (signal
out). Measured votage must be 0,12V DC +/- 5%.

When a failure was found during one of above
checks, replace rack position feedback sensor B14.

06.10.05.02 Check throttle potentiometer B13 (accelerator)
(= connector X13)
In case of defective potentiometer accelerator B13,
service codes 23, 24 or 29 will flash.
NOTE:
First check cables and
connections.

* Resistance between terminals 5 and 4; 1,2 kOhm
* Resistance between terminals 5 and 2; 2,2 kOhm
for normal position of potentiometer accelerator ;
1,4 kOhm at "full speed " max. impact.
* Resistance between terminals 3 and 1; 1,2 kOhm
With approx. 10% of max. first route, resistance
value must increase infinetely high ==>
(disconnection).
