(4) Measure the resistance between joint connector (3) 

terminal 14 and intermediate connector terminal 23.

OK: 2 ohms or less

(5) Measure the resistance between joint connector (3) 

terminal 3 and intermediate connector terminal 22.

OK: 2 ohms or less

CAUTION

Strictly observe the specified wiring harness repair proce-
dure. For details refer to 

P.54C-5

.

Q: Do all the resistances measure 2 ohms or less?

YES : If all the resistances measure 2 ohms or less, power 

supply to the SRS-ECU may be suspected. Diagnose 
the supplemental restraint system. Refer to GROUP 
52B, SRS air bag diagnosis 

P.52B-30

.

NO :  If either of the resistances measures more than 2 

ohms or all the resistances measure more than 2 
ohms repair the wiring harness between joint 
connector (3) and the SRS-ECU connector.

DIAGNOSTIC ITEM 24: Failure in the lines between CAN main bus line and the combination meter.

CAUTION

by touching a metal object such as an unpainted 
water pipe. If you fail to do so, a component con-
nected to the CAN bus line may be damaged.

TROUBLE JUDGMENT
If the MUT-III cannot received signals from the com-
bination meter, CAN bus line connector(s) are bro-
ken or an open circuit has occurred.

.

COMMENTS ON TROUBLE SYMPTOM
The wiring harness wire or connectors may have 
loose, corroded, or damage terminals, or terminals 
pushed back in the connector, or the combination 
meter may be defective.

.

TROUBLESHOOTING HINTS

• The wiring harness or connectors may have 

loose, corroded, or damage terminals, or termi-
nals pushed back in the connector

• The combination meter may be defective

DIAGNOSIS

Required Special Tool:

• MB991223: Harness Set

STEP 1. Check joint connector (3) C-02 and combination 
meter connector C-101 for loose, corroded or damaged 
terminals, or terminals pushed back in the connector.

CAUTION

The strand end of the twisted wire should be within 10 cm 
(4 inches) from the connector. For details refer to 

P.54C-4

.

Check the joint connector at the wiring harness side for loose, 
corroded or damaged terminals, or terminals pushed back in 
the connector, and also check the short pin behind the connec-
tor for corrosion, deformation and delamination.
Q: Are joint connector (3) C-02 and combination meter 

connector C-101 in good condition?
YES : Go to Step 2.
NO :  Repair the damaged parts. Replace the joint 

connector as necessary.
