CUSTOMER CONCERN The high-voltage battery warning is illuminated and the energy-management module stores fault 8526361 / B1802 F1 [008]. CAUSE The high-voltage battery was confirmed failed, triggering the battery warning and stored energy-management fault. CORRECTION Remove and replace the failed high-voltage battery assembly, clear fault 8526361 / B1802 F1 [008], and verify the high-voltage warning remains off and the hybrid system operates normally.

CUSTOMER CONCERN After a driver-side wheel impact and suspension repairs, DTCs C1231, C1A47, and C1626 remain stored for the steering-angle system. CAUSE The steering-angle sensor was confirmed faulty after the collision damage. CORRECTION Remove and replace the failed steering-angle sensor, clear DTCs C1231, C1A47, and C1626, and verify steering-angle data and system operation.

CUSTOMER CONCERN A hybrid-system malfunction warning is displayed and DTCs C1241 and P1CCC96 are stored. CAUSE The DC/DC converter had an internal failure even though the 12-volt charging voltage measured 14.5 volts in READY mode. CORRECTION Remove and replace the failed DC/DC converter/inverter assembly, clear DTCs C1241 and P1CCC96, and verify 12-volt charging operation.

CUSTOMER CONCERN The malfunction indicator lamp is on with DTCs P0031, P0037, P0102, and P0403; the affected sensors and actuators receive only about 8.4 to 8.5 volts even though the EFI No. 2 fuse has 11.7 volts. CAUSE Terminal 4 was loose in connector DA2 at the engine-compartment fuse box, causing excessive voltage loss in the shared EFI No. 2 power circuit. CORRECTION Repair and tighten terminal 4 in connector DA2, clear DTCs P0031, P0037, P0102, and P0403, and verify bat

CUSTOMER CONCERN The engine will not respond normally and DTC P2118 is stored even though the ETCS fuse and throttle-body connector terminals appear serviceable. CAUSE The gray power-supply wire to terminal 3 of ECM connector A57 was corroded inside its insulation near the harness loom, leaving the ECM terminal without battery voltage. CORRECTION Repair the open gray power-supply wire to terminal 3 of ECM connector A57, clear DTC P2118, and verify the engine starts and runs n

CUSTOMER CONCERN The brake pedal is hard and DTCs C1253 and C1256 are stored after body repairs. CAUSE Rodent damage opened the brake-booster pump wiring at its connector, interrupting power to the ABS hydraulic modulator/pump assembly. CORRECTION Repair the rodent-damaged brake-booster pump wiring at the connector, clear DTCs C1253 and C1256, and verify normal brake operation.

CUSTOMER CONCERN After engine-harness replacement, the skid-control ECU stores DTCs C1252, C1253, C1256, and C1345. CAUSE The skid-control ECU with actuator failed after the brake-booster pump power, ground, and direct-operation checks. CORRECTION Remove and replace the failed skid-control ECU with actuator.

CUSTOMER CONCERN DTCs P0A39, P0A4C, and P0A4D are stored for the generator temperature and resolver circuits. CAUSE The hybrid-transmission wiring on top of the transaxle was damaged, opening or shorting the generator resolver circuit. CORRECTION Repair the damaged hybrid-transmission wiring on top of the transaxle.

CUSTOMER CONCERN The engine overheats and stores DTC P261B; the electric water pump reports approximately 6,000 rpm when commanded to 3,000 rpm. CAUSE The engine-coolant pump impeller loosened on its shaft, allowing the motor to overspeed without moving coolant correctly. CORRECTION Remove and replace the failed engine-coolant water pump.

CUSTOMER CONCERN The brake master-cylinder assembly is leaking. CAUSE The brake master-cylinder assembly had an external hydraulic leak. CORRECTION Remove and replace the leaking brake master cylinder, bleed the brake system, and perform the required stroke-sensor zero-point relearn.
