4. Connect voltmeter to measure between negative battery terminal post and a good clean ground on engine

block. See Fig. 5. Rotate and hold ignition switch in Start position. Observe voltmeter. If reading is above
0.2 volt, clean and tighten negative battery cable attachment on engine block. Repeat test. If reading is
still above 0.2 volt, replace faulty negative battery cable. Note: Certain diesel equipped models use
dual batteries. If equipped with dual battery system, this procedure must be performed twice, once
for each battery.

5. Connect positive lead of voltmeter to starter housing. Connect negative lead of voltmeter to negative

battery terminal post. See Fig. 6. Rotate and hold ignition switch in Start position. Observe voltmeter. If
reading is above 0.2 volt, correct poor starter to engine block ground contact. Note: Certain diesel
equipped models use dual batteries. If equipped with dual battery system, this procedure must be
performed on driver side battery only.

6. If equipped with dual battery system (certain diesel equipped models), connect positive lead of voltmeter

to positive battery cable clamp on battery located on left side of vehicle. Connect negative lead of
voltmeter to positive battery terminal post on battery located on right side of vehicle. Rotate and hold
ignition switch in Start position. Observe voltmeter. If reading is above 0.2 volt, clean and tighten battery
cables at both batteries. Repeat test. If reading is still above 0.2 volt, replace faulty positive battery cable.

If resistance tests detect no feed circuit problems, refer to STARTER MOTOR in the Diagnosis and Testing.

CONTROL CIRCUIT TESTING

The starter control circuit components should be tested in the order in which they are listed, as follows:

Starter Relay - Refer to RELAY - STARTER MOTOR. The starter relay is located within the TIPM
(Totally Integrated Power Module). Refer to "*NO CRANK CONDITION " .

Starter Solenoid - Refer to STARTER MOTOR.

Ignition Switch - Refer to Ignition Switch and Key Lock Cylinder in STEERING SYSTEM

Clutch Pedal Position Switch - If equipped with manual transmission, refer to SWITCH-CLUTCH
PEDAL POSITION .

Park/Neutral Position Switch - If equipped with automatic transmission, refer to 42RLE - SERVICE
INFORMATION article .

Wire harnesses and connections - Refer to SYSTEM WIRING DIAGRAMS .

REMOTE STARTING SYSTEM

Before attempting to diagnose a problem with the remote starting system, first be sure the starter motor and
starter solenoid are working properly. The starter should operate with the use of the standard ignition key in the
ignition switch. Any starter or solenoid problems must be repaired first.

Also be sure the engine will easily start and run with the use of the standard ignition key in the ignition switch.
Any engine running, idling or driveability problems must be repaired first.

Also note that the remote start system will automatically be cancelled if any of the following occur:



IF THE ENGINE STALLS OR RPM EXCEEDS 2500



NORMAL TIME OUT RUN MODE (15 MINUTES)


