414-03B-76 414-03B-76 High Voltage/Traction Battery — Nickel Metal Hydride DIAGNOSIS AND TESTING (Continued) PINPOINT TEST B: BATTERY PACK/MODULE(S) VOLTAGE OUT OF RANGE TEST STEP ACTION TO TAKE — 24, 25: between circuit 3096 (W) on in-line C1748F (label M) and battery module 24 (+) post — 25: between circuit 3097 (R/LG) on in-line C1747F (label N) and battery module 25 (+) post • Is the resistance between 28,000 and 34,000 ohms? B6 CHECK OPEN CIRCUIT VOLTAGE OF BATTERY MODULE • Measure the voltage of the battery module(s) in question. Yes = GO to B7. • Is the voltage less than 10.5 volts? No = Battery module OK. B7 INPUT BATTERY MODULE DATA • Remove the traction battery (if necessary) and connect Traction Battery Yes = REPLACE the battery High-Voltage Lockout and Diagnostic Tool to the traction battery module(s) in question. high-voltage two-pin C3994M. • Connect Traction Battery High-Voltage Service Cord to traction battery No = ENTER the indicated data. support tray in-line C1935F and in-line C1935M. REPLACE the battery module(s) in question. WARNING: The traction battery contains high-voltage components and wiring. High-voltage insulated safety gloves and face shield must be worn when carrying out the following steps. Failure to follow this warning may result in severe personal injury or death. • Connect Traction Battery Low-Voltage Service Cord to traction battery support tray in-line C1939F and in-line C1939M. • With key ON, monitor BCM PIDs BAT MC, CHG CYC, and LOWVOLT and enter the values on the Dealer Battery Return Form that is packaged with the new battery module. • Fill out all the required data on the Dealer Battery Return Form and return the form with the damaged battery module. • Is the correct data entered on the Dealer Battery Return Form? B8 CHECK TRACTION BATTERY POSITIVE (+) SENSE LINE CIRCUIT 3214 (LB) BETWEEN BCM AND IN-LINE C1747M FOR OPEN • Remove the traction battery and connect Traction Battery High-Voltage Yes = GO to B9. Lockout and Diagnostic Tool to the traction battery high-voltage two-pin C3994M. • Connect Traction Battery High-Voltage Service Cord to traction battery No = REPLACE high-voltage support tray in-line C1935F and in-line C1935M. harness (10B694). WARNING: The traction battery contains high-voltage components and wiring. High-voltage insulated safety gloves and face shield must be worn when carrying out the following steps. Failure to follow this warning may result in severe personal injury or death. • Connect Traction Battery Low-Voltage Service Cord to traction battery support tray in-line C1939F and in-line C1939M. • With key OFF, disconnect BCM high-voltage C1866. • With key OFF, disconnect in-line C1747 (label N) and measure the resistance of the LB wire between pin 30 on BCM high-voltage C1866 and in-line C1747M. • Is the resistance less than 5 ohms? B9 CHECK TRACTION BATTERY POSITIVE (+) SENSE LINE CIRCUIT BETWEEN IN-LINE C1747F AND BATTERY MODULE 25 FOR OPEN • With key OFF, measure the resistance between the LB wire on in-line C1747F and battery module 25 positive (+) post.
