414-03B-72 414-03B-72 High Voltage/Traction Battery — Nickel Metal Hydride DIAGNOSIS AND TESTING (Continued) Symptom Chart (Continued) Condition Possible Sources Action • DTC C1864 Battery Module • Battery module(s) installed Fault incorrectly (reverse cable polarity). • Incorrect battery module (12-volt) installed. • Battery control module (BCM). • DTC B2236 Weak or • Battery module(s). Defective Electric Vehicle Battery Module Fault • Battery Pack/Module • None. Verification Test Special Tool(s) Pinpoint Tests Traction Battery High-Voltage Service Cord 418-F218 Special Tool(s) Traction Battery Low-Voltage Service Cord 418-F219 104-Pin Breakout Box (BOB) 418-049 (014-00950) or Traction Battery High-Voltage Lockout and Diagnostic equivalent Tool 418-F207 BCM/TIM Breakout Box (BOB) Adapter Cable High-Voltage Insulated Safety Gloves 100-F036 or 418-F212 equivalent BCM/TIM Breakout Box (BOB) Overlay 418-F220 Face Shield 100-F035 or equivalent (Continued) PINPOINT TEST A: DTC P1755 POWER LIMIT SHUTDOWN FAULT TEST STEP ACTION TO TAKE A1 CHECK FOR OTHER TRACTION INVERTER MODULE (TIM) DIAGNOSTIC TROUBLE CODES (DTCs) NOTE: DTCs must be retrieved from the interface adapter assembly (IAA) Yes = module before retrieving DTCs from the TIM. If IAA module DTC C1774 Coolant Temperature Sensor Out of Range occurs, refer to Section 303-03 before proceeding. • Retrieve DTCs from the TIM. • Does DTC C1854 Motor Temperature Out of Range also occur? No = GO to A2. A2 CHECK BATTERY CONTROL MODULE (BCM) FOR DTCs • Retrieve DTCs from the BCM. Yes = • Do any BCM DTCs occur? No = GO to A3. A3 CHECK DIFFERENCE BETWEEN COOLANT TEMPERATURE AND MOTOR/TRANSAXLE TEMPERATURE • With key ON, monitor IAA module PID CLNTTMP and TIM PID Yes = REPLACE the MTRTMP. • Is the temperature difference between the CLNTTMP and No = MTRTEMP PIDs greater than 30 ° C (86 ° F)? PINPOINT TEST B: BATTERY PACK/MODULE(S) VOLTAGE OUT OF RANGE TEST STEP ACTION TO TAKE B1 CHECK FOR OTHER BATTERY CONTROL MODULE (BCM) DIAGNOSTIC TROUBLE CODES (DTCs) • Carry out the on-demand self-test for the BCM.
