|
NOTE: DTC U3500:17, B1317, B1318, B2486, B1676, U3003:16 or U3003:17 can be set if the vehicle has been recently jump started, the battery has been recently charged or the battery has been discharged. The battery may become discharged due to excessive load(s) on the charging system from aftermarket accessories or if the battery has been left unattended with the accessories on. NOTE: Do not allow the engine speed to increase above 2,000 rpm while performing this step or the generator may self-excite and result in default charging system output voltage. If engine speed goes above 2,000 rpm, shut the vehicle OFF and restart the engine before performing this step.
Are the voltages between 13 and 15.2 volts?
