DIAGNOSIS AND REPAIR WORK FLOW 2, work Flow (With GR8-1200 NI) 2, work Flow (Without GR8-1200 NI) 5, fOR MEXICO : Precaution for Supplemental Restraint System (SRS) "AIR BAG" "SEAT BELT.
Wiring Diagram - STARTING SYSTEM - 11, dIAGNOSIS AND REPAIR WORK FLOW, sTARTING SYSTEM DIAGNOSIS WITH GR8-1200 NI, to test the starting system, use the following special service tool.
NI Multitasking battery electrical diagnostic station, refer to the diagnostic station Instruction Manual for proper starting system diagnosis procedures, to ensure a complete and thorough diagnosis, the battery, starter motor and alternator test segments must be, done as a set start finish.
Perform the starting system test with Multitasking battery and electrical diagnostic station GR8-1200 NI, details and operating instructions, refer to diagnostic station Instruction Manual, cHARGE BATTERY>>Perform the slow battery charging procedure, rEPLACE BATTERY>>Before replacing battery, clean the battery cable clamps battery posts.
Check that the starter motor operates correctly, yES >> Starter motor OK, >> Perform further diagnosis of engine mechanical or engine control system, check that starter motor operates.
YES >> Check ring gear and starter motor drive pinion, compare the engine coolant temperature and the cranking voltage with specifications, minimum Specification of Cranking Voltage Referencing Coolant Temperature, more than (More than 34).
Is the voltage less than specified value, does the starter motor turn smoothly, check that the engine can be rotated by hand, does the engine turn freely by hand.
>> Perform further diagnosis of engine mechanical or powertrain mechanism, refer to the diagnostic station Instruction Manual proper testing procedures, if any malfunction is found, immediately disconnect the battery cable negative terminal, crank the engine and check that engine starts.
Check that the starter motor stops after starting engine, check that the engine turns when cranking, check that the engine speed is not low when cranking, >> Check charge condition, corrosion and connection condition of the battery.
Check that the starter motor runs cranking, charge condition, corrosion and connection condition of the battery, the starter motor plunger closes and provides a closed circuit between the battery starter motor, starter motor is grounded to the engine block.
TCM supplies power to the starter relay starter control relay, inside IPDM E/R when the selector lever is shifted to P N, bCM controls the starter relay inside IPDM E/R, cPU inside IPDM E/R controls starter control relay.
The starter motor plunger closes and the motor supplied with, battery power, which in turn cranks the engine, when the S” terminal is supplied with electric power, the B” terminal is constantly supplied with battery power, perform diagnosis under the condition that engine cannot start by following procedure.
Check that starter motor B” terminal connection clean tight, check voltage between starter motor B” terminal ground, >> Check harness between battery and starter motor open circuit, shift the selector lever to P” N” position.
Check voltage between battery positive terminal and starter motor B” terminal, >> Check harness between the battery and the starter motor poor continuity, check voltage between starter motor case battery negative terminal.
