Hi this strange one Done resistance test
Pins oms
1,2 = 524oms
3,4 = missing pins on 3and 4
5,6 = 530oms
7,8 = no reading at all
9,18 = 15.8oms
10,8 = no reading at all
11,18 = 15.7oms
12,18 = 15.7oms
13,18 = 0.18oms ment to be 15.9
14,18 = 16.6oms
15,18 = 3.5oms
16,18 = 3.6oms
17,18 = 13oms

L shape pins c0244
Pins oms
5,20 no reading
21,20 no reading
24,20 no reading
39,20 no reading
3,17 = 3.90ms
4,17 = 01.0 mrmt to be 16.5
10,17 = 16.5oms
14,17 = 16.6oms
15,17 = 16.4oms
16,17 = 13.3oms
17,18 = 4.1oms
52,17 = 16.4oms
53,17 = 16.0oms
There a few things thst worry me on this one
 
Hi all. Thought I'd add onto this tab instead of creating a new one !



I have a 2006 FL1 2.0 TD4

F4 and orange HDC light present as soon as put in D . N&D illuminates Simultaneously.
Does not change gear in sports mode .

I've changed the 2/4 brake duty solenoid and done some resistance tests as follows

co243 (left hand side larger barrel)

Started with all the sensors .

Turbine pin sensor pin 3-4 - 585 ohms

Vehicle speed sensor 5-5 - 582 ohms

Fluid temp sensor pin 7-8 - 1651ohms ( car was warm so about right )

All sensors tested within range
.
Next I've tested all the solenoids on the same barrel plug .

Shift solenoid a - 174 ohms way out

Shift solenoid b - 177 ohms way out

Shift solenoid c - 176 ohms way out

Low clutch timing solenoid- 172 ohms way out

2-4 brake timing solenoid- 175 ohms way out

Reduction timing solenoid - 170 ohms

Lock up solenoid - 140 ohms

Line pressure ssolenoid- 037 ohms

2-4 brake duty solenoid- 035 ohms

I THEN CHECKED FROM C0932
MAIN TCM PLUG results are as follows

.vehicle speed sensor pins 5-20 1700 ohms

.intermediate speed sensor pins 21-20 1 ohms ●Open circuit?●

.turbine speed sensor pins 24-20 1 ●I belive only the v6 has this ? Using a v6 specs with a jacto Box●

.Fluid temp sensor pins 39-20 1 ohms ●? Open circuit ? This tested good at the barrel plug?●

Solenoids tested from C0932

.2/4 brake duty solenoid pins 3-17 flashes 1500ohms upwards ?

.2/4 brake timing solenoid pins 4-17 flashing 807 ohms upwards?

.Reduction timing solenoid pins 10-17 flashing 400ohms upwards?

.shift solenoid valve A B & C pins 15-17 14-17 52-17 flashing 1300 300 176 ohms ?

.lock up solenoid pins 16-17 flashing 1100 ohms upwards


.line pressure duty solenoid pins 17-18 526 ohms

.shift solenoid c pins 52-17 176 ohms
●funnily enough this is the only one to share the same resistance as tested at barrel plug

.low clutch timing solenoid pins 53-17 210 ohms
Any ideas ? Am I simply looking for a short/ open circuit? Or should I be focusing else where .Thanks

Are you measuring with an auto range meter or manually selecting different ranges yerself?



There's two barrel connectors on the gear box looms. One does the control and monitoring of the auto - sensor/solenoid. The other supplies gear lever position to the auto's computer. The first thing to do is make sure the barrel connectors are pushed together correctly and not coming apart. With the collar twisted, pull them apart gently to see if there's movement. If so tie wrap them together.



Next make sure the LED's next to the gear lever read correctly as you move the gear lever. The dash needs to read correct anorl. Yer can't move forwards with confidence without this part working first.

Thanks for your reply matey!
But yes I've checked the barrel plugs , there both tight and clean!
The light on the gear indicator works as should and always has done until this fault code appeared (f4) and now it illuminates D & N Simultaneously while in D only.
Funnily enough the f4 and the orange HDC light don't come on until I reach D .
In park and neutral the dash reads as normal.
 
I posted the same questions on yer new fred. Can we use that one so as not to confuse peeps.
