PINPOINT TEST C : THE ENGINE CRANKS SLOWLY
TEST CONDITIONS
C1: CHECK FOR VOLTAGE DROP
C2: CHECK FOR GROUND CONNECTION
Disconnect Powertrain Control Module (PCM) C417.
2
Measure the resistance between the starter relay
3
C1017 pin 2, circuit 31S- BB16 (BK/RD), harness side
and the PCM C415 pin 27, 31S-BB16 (BK/RD),
harness side.
Is the resistance less than 1 ohm?
Yes
CHECK the PCM. REFER to the WDS.
No
REPAIR the circuit. TEST the system for normal
operation.
DETAILS/RESULTS/ACTIONS
Ignition switch in position III.
1
Measure the voltage between the starter motor
2
terminal 30, component side and the battery
positive terminal.
Is the voltage less than 0.5 volts?
Yes
GO to C2.
No
CLEAN and TIGHTEN all battery positive cable
connections. TEST the system for normal operation.
If the concern persists, INSTALL a new battery to
starter motor solenoid cable.
