(4) Measure the resistance between intermediate connector
terminal 11 and ABS-ECU connector terminal 25.
OK: 2 ohms or less
(5) Measure the resistance between intermediate connector
terminal 12 and ABS-ECU connector terminal 7.
OK: 2 ohms or less
CAUTION
Strictly observe the specified wiring harness repair proce-
dure. For details refer to
Q: Do all the resistances measure 2 ohms or less?
YES : If all the resistances measure 2 ohms or less, go to
Step 26.
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 intermediate
connector C-29 and the ABS-ECU connector.

STEP 26. Check the CAN bus lines between intermediate
connector C-29 and the joint connector (3). Measure the
resistance between intermediate connector C-29 and joint
connector (3) C-02.
CAUTION
A digital multimeter should be used. For details refer to
CAUTION
The test wiring harness should be used. For details refer to
(1) Disconnect joint connector (3) C-02 and intermediate
connector C-29, and measure the resistance between the
wiring harness side connector of joint connector (3) C-02
and the female side connector of intermediate connector
C-29 (instrument panel wiring harness side).
(2) Turn the ignition switch to the "LOCK" (OFF) position.
CAUTION
Disconnect the negative battery terminal. For details refer
to
.
(3) Disconnect the negative battery terminal.

(4) Measure the resistance between intermediate connector
terminal 11 and joint connector (3) terminal 9.
OK: 2 ohms or less
(5) Measure the resistance between intermediate connector
terminal 12 and joint connector (3) terminal 20.
OK: 2 ohms or less
CAUTION
Strictly observe the specified wiring harness repair proce-
dure. For details refer to
Q: Do all the resistances measure 2 ohms or less?
YES : If all the resistances measure 2 ohms or less, power
supply to the ABS-ECU may be suspected. Diagnose
the ABS system. Refer to GROUP 35B, ABS
diagnosis
.
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 intermediate connector C-29.

DIAGNOSTIC ITEM 16: Diagnose CAN bus lines thoroughly <Vehicles with ABS and vehicles with
multi-center display (middle-grade type)>
CAUTION
When servicing a CAN bus line, ground yourself
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.
