VTSS Indicator Inoperative

WARNING: This page is about a different car, the 2002 Dodge Ram Wagon, 2002 Dodge Ram Van, 2001 Dodge Ram Wagon, and 2001 Dodge Ram Van. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Perform BODY VERIFICATION TEST under VERIFICATION TESTS after each repair

Possible Causes:

Defective Bulb Or Socket
VTSS Indicator Driver Circuit Short To Ground
VTSS Indicator Driver Circuit Open
VTSS Indicator Driver Circuit Short To Ground
CTM VTSS Indicator Driver Circuit
Instrument Cluster
Hard Wired Input To Cluster

Testing

While observing SECURITY light on EMIC, turn ignition on. If SECURITY light illuminates momentarily, go to next step. If SECURITY light does not illuminate momentarily, go to step 5 .
Turn ignition off. Disconnect Central Timer Module (CTM) connector C2. Remove Electro-Mechanical Instrument Cluster (EMIC). See ELECTRO-MECHANICAL INSTRUMENT CLUSTER under REMOVAL & INSTALLATION. Using a DVOM, measure resistance between EMIC connector C1 terminal No. 8 (Yellow/Orange wire) and ground. See Figure . If resistance is more than 100 ohms, go to next step. If resistance is less than 100 ohms, repair short to ground in Yellow/Orange wire.
Using a DVOM, measure resistance of Yellow/Orange wire between CTM connector C2 terminal No. 8 and EMIC connector C1 terminal No. 8. See Figure and Figure . If resistance is less than 5 ohms, go to next step. If resistance is more than 5 ohms repair open in Yellow/Orange wire.
Turn ignition on. Using a DVOM, measure voltage between CTM connector C2 terminal No. 8 (Yellow/Orange wire) and ground. If voltage is more than one volt, repair short to voltage in VTSS indicator driver circuit. If voltage is one volt or less, replace CTM.
Turn ignition off. Remove EMIC. See ELECTRO-MECHANICAL INSTRUMENT CLUSTER under REMOVAL & INSTALLATION. Remove and inspect SECURITY light bulb and socket. Repair or replace SECURITY light bulb and/or socket as necessary. If SECURITY light bulb and socket are okay, go to next step.
Using wiring diagram as a guide, determine if correct voltage or ground is present at EMIC inputs. See GROUND DISTRIBUTION and POWER DISTRIBUTION in appropriate SYSTEM WIRING DIAGRAMS article in ELECTRICAL. Repair ground or voltage inputs at EMIC as necessary. If ground and correct voltage is present at EMIC inputs, replace EMIC. See ELECTRO-MECHANICAL INSTRUMENT CLUSTER under REMOVAL & INSTALLATION.
