Diagnostic Procedure with Diagnostic Trouble Code (DTC)
CRUISE CONTROL SYSTEM (DIAGNOSTICS)
Step Check Yes No
1CHECK STOP LIGHT SWITCH AND BRAKE
SWITCH CIRCUIT.
1) Turn the ignition switch to OFF.
2) Disconnect the stop light switch and brake
switch harness connector.
3) Turn the ignition switch to ON.
4) Measure the voltage between harness con-
nector terminal and chassis ground.
Connector & terminal
(B65) No. 2 (+) — Chassis ground (–):
Is the voltage more than 10 V? Go to step 2.•Check fuse No.
8 (in fuse & relay
box).
•Check for open
or short in the har-
ness between stop
light/brake switch
and fuse & relay
box.
2CHECK STOP LIGHT SWITCH AND BRAKE
SWITCH CIRCUIT.
Measure the voltage between harness connec-
tor terminal and chassis ground.
Connector & terminal
(B65) No. 4 (+) — Chassis ground (–):
Is the voltage more than 10 V? Go to step 3.•Check fuse No.
4 (in fuse & relay
box).
•Check for open
or short in the har-
ness between stop
light/brake switch
and fuse & relay
box.
3CHECK STOP LIGHT SWITCH AND BRAKE
SWITCH CIRCUIT.
1) Turn the ignition switch to OFF.
2) Disconnect the harness connector of ECM.
3) Measure the resistance between ECM har-
ness connector terminal and stop light switch
and brake switch harness connector terminal.
Connector & terminal
(B135) No. 28 — (B65) No. 3:
(B135) No. 20 — (B65) No. 1:
Is the resistance less than 10
Ω?
Go to step 4.Repair the har-
ness.
4Check Stop Light Switch and Brake Switch
Remove and check the stop light switch and
brake switch. Brake Switch.>
Are the stop light switch and
brake switch OK?
Replace the ECM.

Engine Control
Module (ECM).>
Replace the stop
light switch and

CRUISE CONTROL SYSTEM (DIAGNOSTICS)
E: DTC 22 AND 32 VEHICLE SPEED SENSOR
DIAGNOSIS:
Open or short circuit in vehicle speed sensor system.
TROUBLE SYMPTOM:
Cruise control cannot be set. (Cancelled immediately.)
Step Check Yes No
1 CHECK IGNITION SWITCH CIRCUIT
1) Turn the ignition switch to OFF.
2) Disconnect the ECM harness connector.
3) Turn the ignition switch to ON.
4) Measure the voltage between harness con-
nector terminal and chassis ground.
Connector & terminal
(B135) No. 19 (+) — Chassis ground (–):
Is the voltage more than 10 V? Check poor con-
tact of ECM con-
nector.
•Check fuse No.
12 (in fuse & relay
box).
•Check the har-
ness for open or
short circuit
between ignition
switch and ECM.
Step Check Yes No
1CHECK ABS WARNING LIGHT.
1) Turn the ignition switch to ON.
2) After the initial operation of combination
meter is completed, check if the VDC warning
light continues to illuminate.
Does the VDC warning light
continue to illuminate?
Check the
VDCCM. VDC(diag)-2,
Basic Diagnostic
Procedure.>
Go to step 2.
2CHECK LAN COMMUNICATION CIRCUIT
ERROR DISPLAY
Check if the communication error is displayed
on the odo/trip meter in combination meter.
Is the error code «Er xx» dis-
played on odo/trip meter?
Check the LAN
communication cir-
cuit. LAN(diag)-2, Basic
Diagnostic Proce-
dure.>
