B2617 STARTER RELAY CIRCUIT
B2617 STARTER RELAY CIRCUIT
DescriptionINFOID:0000000009461176
Located in IPDM E/R, it runs the starter motor. The starter relay is turned ON by the BCM when the ignition
switch is in START position. IPDM E/R transmits t he starter relay ON signal to BCM via CAN communication.

HYDRAULIC PUMP ELECTRIC POWER STEE RING SYSTEM : Protection Function
INFOID:0000000009460346
• When the steering wheel is operated repeatedly or turned all the way for a long period during parking or low
speed driving, the function of the hydraulic pump elec tric power steering system becomes limited to prevent
the system from overheating. Cont inued operation of the steering wheel will cause the hydraulic pump elec-
tric power steering system to stop and the hydraulic pum p electric power steering system warning lamp may
come ON. In this case, the steering wheel operation temporarily becomes hard. This is not a malfunction.
When the engine is turned OFF (ignition switch OFF) and steering operation is stopped for a while, the tem-
perature of the hydraulic pump electric power steer ing system decreases and the steering operation returns
to normal after restarting the engine.
• Then, the hydraulic pump electric power steering syste m warning lamp turns OFF. If the system is OFF
under the protection state, the hydraulic pump electr ic power steering system warning lamp turns ON to
warn that the system is in the manual steering state. (This is not a system malfunction.) In addition, the fol-
lowing DTC remains to distinguish from malfunction.

If the cause is in a different ECU, the state changes to fixed steering assist force.

Fail-safeINFOID:0000000009460349
When an error occurs in the hydraulic pump electric pow er steering system, fail-safe brings the system to a
halt (manual steering) or restricted (constant steering assi st level) state. When the system is in a halt state,
fail-safe turns ON the hydraulic pump electric power steer ing warning lamp to warn the driver that the hydrau-
lic pump electric power steering system is in the manual steering state.
Protection FunctionINFOID:0000000009460350
• When the steering wheel is operated repeatedly or turned all the way for a long period during parking or low
speed driving, the function of the hydraulic pump elec tric power steering system becomes limited to prevent
the system from overheating. If the steering wheel is operated further more, the hydraulic pump electric
power steering system stops and the hydraulic pump el ectric power steering system warning lamp may be
turned ON. In this case, the steering wheel operation temporarily becomes hard. This is not a malfunction.
When the engine is turned OFF (ignition switch OFF) and steering operation is stopped for a while, the tem-
perature of the hydraulic pump electric power steeri ng system decreases and the steering operation returns
to normal after restarting the engine.
