INSPECTION PROCEDURE
1 Check voltage between terminal CCS of ECM connector and body ground.
PREPARATION:
(a) Remove the ECM with connector still connected.
(b) Turn ignition switch ON.
CHECK:
Measure voltage between terminal CCS of ECM connector and
body ground, when each of the -/SET, +RES and CANCEL is
turned ON.
OK:
Switch PositionVoltage
Neutral9 - 14 V
+/RES2.1 - 4 V
-/SET4 - 7.1 V
CANCEL6 - 10.1 V
OK Proceed to next circuit inspection shown on
problem symptom table (See page DI-991).

CIRCUIT INSPECTION
DTC B2603 Tilt and Telescopic Manual switch circuit
Malfunction
CIRCUIT DESCRIPTION
The different voltage value is input to tilt and telescopic ECU by operating the manual switch. Then tilt and
telescopic ECU judges which motor and which direction tilt motor or telescopic motor should be moved based
on the voltage value.
DTC No.DTC Detecting ConditionTrouble Area
B2603
The abnormal voltage value which is not within the specifi-
cation is input to tilt and telescopic ECU when being oper-
ated with the manual switch.
