The right and left turn indicators will illuminate when the multifunction switch is in either turn signal position or hazard lamps position and sends a battery signal to the instrument cluster.
Air Bag Indicator
The air bag indicator will be illuminated when the restraint control module (RCM) sends a ground signal to the instrument cluster. The prove out of the air bag indicator is controlled by the
RCM.
Anti-Theft Indicator
The THEFT indicator provides passive anti-theft system (PATS) prove out. The THEFT indicator will prove out for three seconds following the ignition switch cycle and will flash following the
ignition OFF to indicate that PATS is active.
Charging System Indicator
The charging system indicator will be illuminated when the generator sends a ground signal to the instrument cluster.
Speed Control
The speed control (CRUISE) indicator is controlled by the speed control servo and hardwired to the instrument cluster.
4X4 High Indicator
The 4X4 high indicator will be illuminated when the vehicle is in 4X4 high mode and the GEM sends a ground signal to the instrument cluster. The 4X4 high indicator will prove out when the
ignition switch is placed in the START position and then in the RUN position.
Low Range Indicator
The LOW RANGE indicator will be illuminated when the vehicle is in 4X4 low and the PCM sends a message to the instrument cluster via the SCP network. The low range indicator will
prove out when the ignition switch is placed in the START position and then in the RUN position.
Door Ajar Indicator
The door ajar indicator will prove out when the ignition switch is placed in the START position and then in the RUN position. The door ajar indicator will be illuminated when the CTM/GEM
provides a ground signal to the instrument cluster.
Low Fuel Indicator
The low fuel indicator will prove out when the ignition switch is placed in the START position and then in the RUN position. The low fuel indicator will illuminate when the fuel level gets low.
The instrument cluster receives the fuel level information directly from the fuel sender.
Inspection and Verification
1. Verify the customer concern by operating the instrument cluster to duplicate the condition. Observe the indicators, warning displays, and gauges to determine if they are operating
correctly with the ignition switch:
in RUN with the engine off.
in START before the ignition switch is released.
in RUN with the engine running.
2. Visually inspect for obvious signs of mechanical and electrical damage.
Visual Inspection Chart
3. If the inspection reveals obvious concern(s), repair as required.
4. If the cause of the fault is not visually evident, proceed to the diagnostic tool diagnostics.
Diagnostic Tool Diagnostics
1. If the concern remains after the inspection, connect the diagnostic tool to the data link connector (DLC) located beneath the instrument panel and select the vehicle to be tested from
the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle:
Check that the program card is correctly installed.
Check the connections to the vehicle.
Check the ignition switch position.
2. If the diagnostic tool still does not power up, refer to the diagnostic tool manual.
3. Carry out the diagnostic tool data link test. If the diagnostic tool responds with:
SCP or ISO = all electronic control units no response/not equipped, refer to Section 418-00.
No response/not equipped for hybrid electronic cluster (HEC), GO to Pinpoint Test A.
No response/not equipped for generic electronic module/central timer module (GEM/CTM), GO to Pinpoint Test B.
System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and carry out self-test diagnostics for the HEC, and
GEM/CTM.
4. If the DTCs retrieved are related to the concern, go to the Hybrid Electronic Cluster (HEC) Diagnostic Trouble Code (DTC) Index, or the Generic Electronic Module (GEM)/Central
Timer Module (CTM) Diagnostic Trouble Code (DTC) Index to continue diagnostics.
