DIAGNOSTICS - ASSEMBLY INSTRUMENT 04-957

Diagnostic step

1 . Check the CAN communication line.

(a) Ignition Switch:ON.

(b) Disconnect the engine ABS/ESP connector
A08, the ignition switch at "ON" position, 04
check the voltage between pin 14 and pin 26
of A08 and the ground.
A006
Standard voltage
13 12 11 10 9 8 7 6 5 4 3 2 1
24 23 22 21 20 19 18 17 16 15 14
38 37 36 35 34 33 32 31 30 29 28 27 26 25 Multimeter connection Standard value
A006 (14 )- ground 0V～2.5V
14 26
A006 (26) - ground 2.5V～5V

(c) Disconnect the battery negative cable, check
the resistance between pin 14 and pin 26 of
ftwxd041451 A08.
Standard resistance: 60Ω

(d) Disconnect combination meter connector,
check the continuity between pin 26 pin of
engine ABS/ESP connector A08 and No.16
pin of combination meter connector C23, and
the continuity between pin 14 pin of A08 and
pin 15 pin of combination meter connector
C23.

Check whether the result is normal?
Yes> go to step 3

No >Check whether CAN communication terminal resistance A023 is intact, and repair
the corresponding CAN communication harness open circuit fault.

2 . Replacement inspection
(a) Replace the same combination meter, perform the speed test, check whether the fault
is eliminated.
Check whether the result is normal?

Yes> replace combination instrument assembly.
No >Remove fault from other symptoms.
