TEST E: COOLANT TEMPERATURE GAUGE INACCURATE OR INOPERATIVE

1. Perform instrument panel cluster system diagnostic system check. See INSTRUMENT PANEL CLUSTER SYSTEM DIAGNOSTIC SYSTEM CHECK under SELF-
DIAGNOSTIC SYSTEM. If instrument panel cluster system diagnostic system check has been performed, go to next step.

2. Connect scan tool to Data Link Connector (DLC). Turn ignition switch to RUN position. Using scan tool, perform COOLANT GAGE SWEEP TEST. If engine coolant temperature gauge move up and down on command, check for intermittent problem. See DIAGNOSING INTERMITTENTS. Repair or replace as necessary. After repair, go to step 4. If engine coolant temperature gauge does not move up and down on command, go to next step.

3. Replace Instrument Panel Cluster (IPC). After repair, go to next step.

4. Operate system to verify repair. If system operates normally, repair is complete. If system does not operate normally, return to step 2.

INSTRUMENT PANEL CLUSTER SYSTEM DIAGNOSTIC SYSTEM CHECK

NOTE: Use this check as starting point for any instrument panel cluster system complaint.

1. Connect scan tool to Data Link Connector (DLC). If scan tool powers up, go to next step. If scan tool does not power up, go to SCAN TOOL DOES NOT POWER UP under SYSTEM TESTS in BODY CONTROL MODULES - IMPALA & MONTE CARLO article.

2. Turn ignition switch to RUN position. Using scan tool, attempt to establish communications with following modules:

Body Control Module (BCM)
Powertrain Control Module (PCM)
Electronic Brake Control Module (EBCM)
Inflatable Restraint & Sensing Diagnostic Module (SDM)

If communication is established with all modules, go to next step. If communication cannot be established any module, go to SCAN TOOL DOES NOT COMMUNICATE WITH CLASS 2 DEVICE under SYSTEM TESTS in BODY CONTROL MODULES - IMPALA & MONTE CARLO article.

3. Select scan tool display DTCs function for following control modules:

Body Control Module (BCM)
Powertrain Control Module (PCM)
Electronic Brake Control Module (EBCM)
Instrument Panel Cluster (IPC)
Inflatable Restraint Sensing & Diagnostic Module (SDM)

If scan tool displays any DTCs, go to next step. If scan tool does not display any DTCs, perform appropriate procedure.

4. Using scan tool, retrieve DTCs. If DTCs U1000-U1305 are not present, go to next step. If DTCs U1000-U1305 are present, go to SCAN TOOL DOES NOT COMMUNICATE WITH CLASS 2 DEVICE under SYSTEM TESTS in
BODY CONTROL MODULES - IMPALA & MONTE CARLO article.

5. Check for DTCs B1000, B1007, B1009, B1339, B1349 or B1440. If DTCs are not present, go to next step. If any DTC is present, perform appropriate test. See DIAGNOSTIC TROUBLE CODE DEFINITIONS under SELF-DIAGNOSTICS in BODY CONTROL MODULES - IMPALA & MONTE CARLO article.

6. Check for DTCs B1482, B1483, B1507, B1508, P0560 or P0620. If DTCs are not present, test is complete. If any DTC is present, go to DIAGNOSTIC TROUBLE CODE DEFINITIONS.
