Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"

The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.

Information necessary to service the system safely is included in the SRS AIRBAG and SEAT BELTS articles of this Service Information.

Scheme 10

The starter motor plunger closes and provides a closed circuit between the battery and the starter motor. The starter motor is grounded to the cylinder block. With power and ground supplied, the starter motor operates.

Scheme 11

1. When the selector lever is in the P or N position, power is supplied to starter relay and starter control relay by the transmission range switch. The BCM and IPDM E/R (CPU) will detect the selector lever position by the input signal.
2. When the starter operating condition is meet, the IPDM E/R will turn the starter control relay ON by starter control relay control signal.
3. When engine cranking condition is meet, the BCM turns ON the starter relay by starter control relay signal.
4. Then battery power is supplied to starter motor ("S" terminal) through the starter control relay and starter relay.

REPLACE BATTERY: Before replacing battery, clean the battery cable clamps and battery posts. Perform battery test again. Refer to diagnostic station instruction manual. If second test result is "REPLACE BATTERY", then do so. Perform battery test again to confirm repair.
2. CRANKING CHECK Check that the starter motor operates properly. Does the engine crank normally? YES: GO TO 3. NO: GO TO 5 .
3. ENGINE START CHECK Check that the engine starts. Does the engine start? YES: Inspection End. NO: Perform further diagnosis of engine mechanical or engine control system. Refer to Engine Mechanical and Engine Control articles. Once resolved, perform battery test again.
4. STARTER MOTOR ACTIVATION Check that the starter motor operates. Does the starter motor turn? YES: Check ring gear and starter motor drive pinion. Once resolved, perform battery test again. NO: GO TO 7 .
5. COMPARISON BETWEEN ENGINE COOLANT AND CRANKING VOLTAGE Compare the engine coolant temperature and verify the cranking voltage is within specifications. MINIMUM SPECIFICATION OF CRANKING VOLTAGE REFERENCING COOLANT TEMPERATURE Engine coolant temperature [°C (°F)] Voltage [V] -30 to -20 (-22 to -4) 8.6 -19 to -10 (-2 to 14) 9.1 -9 to 0 (16 to 32) 9.5 More than 1 (More than 34) 9.9 Is the voltage less than the specified value? YES: GO TO 7 . NO: GO TO 6.
6. STARTER OPERATION Check the starter operation. Does the starter motor turn smoothly? YES: Inspection End. NO: GO TO 7.
7. "B" TERMINAL CIRCUIT INSPECTION Check "B" terminal circuit. Refer to " «DIAGNOSIS PROCEDURE»(ref-605948-S32851541522014032500000) ". Is "B" terminal circuit normal? YES: GO TO 8. NO: Repair as needed.
8. "S" CONNECTOR CIRCUIT INSPECTION Check "S" connector circuit. Refer to " «DIAGNOSIS PROCEDURE»(ref-605948-S04116071082014032500000) ". Is "S" connector circuit normal? YES: GO TO 9. NO: Repair as needed.
9. ENGINE ROTATION STATUS Check that the engine can be rotated by hand. Does the engine turn freely by hand? YES: Replace starter motor. NO: Perform further diagnosis of engine mechanical or powertrain mechanism. Once resolved, perform battery test again using Multitasking battery and electrical diagnostic station GR8-1200 NI. Refer to the diagnostic station Instruction Manual for proper testing procedures.
