(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 29.
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 29. 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 17: Diagnose the lines between CAN main bus line and the powertrain control
module <Vehicles without ABS>
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.
