INSTRUMENT PANEL 1995 ACCESSORIES & SAFETY EQUIPMENT Chrysler Corp. Instrument Panel (2024)

DESCRIPTION & OPERATION

Instrument cluster gauges include coolant temperature, fuel level, and tachometer gauge. All gauges are magnetic type. Speedometer and odometer are electronically driven. Low fuel level and oil pressure is indicated by a warning light. Instrument panel switches include foglight, headlight, and rear defogger.

TESTING

FOGLIGHT SWITCH TEST

Remove Foglight switch. See FOGLIGHT & REAR DEFOGGER SWITCHES under REMOVAL & INSTALLATION. Using jumper wires, apply battery voltage to switch terminals No. 2 and 4. See Fig.1. Connect a test light to switch terminal No. 3. Press foglight switch button. Foglight switch LED and test light should illuminate. If LED or test light does not illuminate, replace foglight switch.

FUEL LEVEL SENSOR

Using ohmmeter, check resistance between sensor signal and sensor ground terminals of fuel pump module connector with fuel lever sensor in indicated positions. See FUEL LEVEL SENSOR RESISTANCE table. See Fig.2.

LOW FUEL WARNING LIGHT TEST

Verify fuel gauge is operating correctly. If fuel gauge is okay, check for burned-out bulb or bad connection. If low fuel warning light still does not operate under a low fuel condition, replace printed circuit board.

LOW OIL PRESSURE WARNING LIGHT TEST

1. Turn ignition on. If warning light does not illuminate, check for a loose or open wire at oil pressure switch located at front of engine. If wire is okay, go to next step.
2. Turn ignition off. Disconnect oil pressure switch connector. Using jumper wire, ground connector to engine. Turn ignition on. If warning light does not illuminate, check for burned-out bulb or disconnected socket. If warning light illuminates, check oil pressure. If oil pressure is okay, replace oil pressure switch.

HEADLIGHT SWITCH

Remove headlight switch. See HEADLIGHT SWITCH under REMOVAL & INSTALLATION. Using ohmmeter, check for continuity between indicated terminals. See HEADLIGHT SWITCH RESISTANCE SPECIFICATIONS table. See Fig.4. If continuity is not as specified, replace headlight switch.

INDIVIDUAL INSTRUMENT CLUSTER GAUGE INOPERATIVE TESTS

Before removing instrument cluster to check a suspected faulty gauge, perform this test: Locate and disconnect harness connector from suspected faulty gauge sending unit. Ground sending unit harness connector leads. Turn ignition on. Gauge should read at or above maximum. If gauge does not read as indicated, check sending unit and wiring. Repair as necessary. If gauge reads as indicated, perform appropriate gauge test.

Coolant Temperature Gauge

1. Disconnect sending unit. See Fig.5. Turn ignition on. Gauge should read at lowest position. Turn ignition off. Ground sending unit connector pin No. 3. Turn ignition on. Gauge should read at maximum. After seat belt warning light goes out, cluster should chime for 8 seconds.
2. If gauge operates as indicated, check sending unit connector for proper connection. If connection is okay, replace sending unit. If gauge does not operate as indicated, replace gauge. If gauge is still not operating properly, replace printed circuit board.

Fuel Gauge

1. If fuel gauge indicates empty with fuel in tank, go to step 4). Disconnect sending unit. Turn ignition on. Gauge should read at lowest position. Turn ignition off. Ground sending unit connector pin No. 4. Turn ignition on. Gauge should read at maximum. Turn ignition off, then on after a sending unit signal change to by-pass cluster electronic gauge dampening mechanism.
2. If gauge operates as indicated, check sending unit connector for proper connection. If connection is okay, check fuel level sensor. See FUEL LEVEL SENSOR under TESTING. If gauge does not operate as indicated, go to next step.
3. Remove gauge. Using ohmmeter, check resistance of sending unit wiring to gauge. Resistance should vary between 50-1080 ohms according to fuel level. Repair wiring as necessary. If wiring is okay, replace gauge. If gauge is still not operating properly, replace printed circuit board.
4. If fuel gauge indicates empty with fuel in tank, Powertrain Control Module (PCM) may be sending a false reading due to an open circuit. Using ohmmeter, check for continuity between instrument cluster J2 connector pin No. 10 and PCM pin No. 13. See INSTRUMENT CLUSTER CONNECTOR TERMINAL IDENTIFICATION table. See Fig.6 and Fig.7. If continuity does not exist, repair as necessary. If continuity exists, return to step 1) and continue with rest of test.

MULTIPLE INSTRUMENT CLUSTER GAUGES INOPERATIVE TEST

1. Remove instrument cluster. See INSTRUMENT CLUSTER under REMOVAL & INSTALLATION. Turn ignition on. Using voltmeter, check for battery voltage at cluster wiring harness J1 connector pin No. 5. Check for battery voltage at cluster wiring harness J1 connector pin No. 6. See INSTRUMENT CLUSTER CONNECTOR TERMINAL IDENTIFICATION table. See Fig.6. If battery voltage does not exist at either or both pins, repair as necessary.
2. Using ohmmeter, check for continuity between ground and J1 connector pin No. 8. If continuity does not exist, repair as necessary. If continuity exists, check for damaged pins or connector. If connector is okay, replace printed circuit board.

REAR DEFOGGER SWITCH TEST

For testing information on rear defogger switch, see DEFOGGER - REAR WINDOW article in the ACCESSORIES/SAFETY EQUIPMENT section.

SPEEDOMETER TEST

See appropriate Vehicle Speed Sensor (VSS) testing in TESTS W/CODES - 2.0L VINS [C,Y] & 2.4L VIN [X] article in the ENGINE PERFORMANCE section.

TACHOMETER TEST

1. Remove instrument cluster. See INSTRUMENT CLUSTER under REMOVAL & INSTALLATION. Using voltmeter, check for battery voltage at cluster wiring harness J1 connector pin No. 6. See INSTRUMENT CLUSTER CONNECTOR TERMINAL IDENTIFICATION table. See Fig.6.
2. Turn ignition on. Check for battery voltage at cluster wiring harness J1 connector pin No. 5. Using ohmmeter, ensure continuity exists between ground and J1 connector pin No. 8. If voltage and resistance are not as specified, repair as necessary. If voltage and resistance are okay, go to next step.
3. Using a voltmeter in AC mode, check voltage between ground and J1 connector pin No. 7 with engine running. If reading is less than one volt, go to next step. If reading is at least one volt, replace tachometer gauge. If tachometer still does not work properly, replace printed circuit board.
4. Using ohmmeter, check for continuity between J1 connector pin No. 7 and Powertrain Control Module (PCM) connector pin No. 37. See Fig.6 and Fig.7. Check PCM connector for damaged or pushed-out pins. Repair wiring or connector as necessary. If continuity exists and PCM connector is okay, replace PCM.

VEHICLE SPEED SENSOR (VSS)

See appropriate Vehicle Speed Sensor (VSS) testing in TESTS W/CODES - 2.0L VINS [C,Y] & 2.4L VIN [X] article in ENGINE PERFORMANCE section.

WIPER/WASHER SWITCH TEST

For testing information on wiper/washer switch, see WIPER/WASHER SYSTEM article in the ACCESSORIES/SAFETY EQUIPMENT section.
