high/erratic idle and/or the MIL light on. In some cases, vacuum leak noise may be heard as well. There may be poor contact or loss of contact at various main ground points or electrical connections. Power steering pressure switch may be shorted with debris. Inlet manifold gasket may be leaking. Broadcast code and calibration part number may need to be updated. To correct this condition, follow the procedures outlined in this bulletin to determine proper diagnosing, inspection and correction of ground contact points for proper electrical contact, power steering pressure switch cleaning or replacement and power steering system flush, replacement of inlet manifold gasket, and/or PCM reprogramming. SERVICE PROCEDURE Please refer to the appropriate workshop manual for the correct diagnosing procedure and/or follow the service procedures outlined in this bulletin for the vehicle being serviced. 1. Inspect main ground points (refer to SB99-04-S001 for more information). P6 ground point-body [on the passenger side of engine compartment, between the battery and cruise control actuator (if equipped)]. (Figure Fig. 1 ) P10 ground point-engine (at the alternator bracket). (Figure Fig. 2 ) The 1998, 1999 or 2000 Rodeo/Amigo Electrical Troubleshooting Manual can assist in locating the vehicle ground distribution (i.e., ground contact points). Perform a voltage drop test at the main ground points. If the voltage drop test fails, then inspect and clean both the bolt and

Some 2000-2009 Focus vehicles may exhibit an excessive engine vibration at idle, most noticeable when the transmission is engaged in reverse. This condition may be caused by small stones, road debris, ice or snow packed / lodged in the rear engine roll restrictor. ACTION: Inspect the rear engine roll restrictor for debris and install service shield if necessary. SERVICE PROCEDURE 1. 2. 3. 4. 5. Inspect the rear engine roll restrictor for debris. Remove any debris from rear engine roll restrictor. Remove the cross member-to-roll restrictor attachment bolt. Install service shield. (Figure 1) Install roll restrictor attachment bolt and torque to 35 lb-ft (47 N-m).

Subject: Models: Low Engine Coolant Level Indicator Always On (Diagnose Low Coolant Level System Operation/Check Sensor for Oil Contamination) 2000-2002 Buick Century, Regal 2000-2001 Chevrolet Lumina 2000-2002 Chevrolet Impala, Monte Carlo 2000-2002 Pontiac Grand Prix 2000-2002 Oldsmobile Intrigue Condition Some customers may comment that the low engine coolant level indicator is always illuminated. Cause The cause of this condition may be due to engine oil contaminating the coolant. Possible sources of oil contamination are internal engine leaks, improper service procedures, or the addition of some types of anti-leak additives to the cooling system. Once in the coolant, the oil leaves deposits on the level sensor creating an insulating film. This film results in a false activation of the coolant level indicator. Correction Diagnose low coolant level system operation and check the sensor for oil contamination using the procedure listed below. Important: No coolant supplements should be used in GM cooling systems, other than what is approved and recommended by GM. The use of “aftermarket” over-the-counter sealing and cooling supplements may affect the operation of the low coolant level sensor. Discoloration of the coolant recovery bottle is normal and does not necessarily indicate that coolant contamination is present. Flush cooling system only when instructed by this bulletin. 1. Verify that the coolant is at proper level in the radiator and the coolant recovery bottle. If the coolant is low, add proper amount of 50/50 water and DEX-COOL® mixture. If the low coolant light operates properly, diagnose the cooling system for loss of coolant as outlined in SI. DO NOT proceed further with this bulletin. 2. Remove the low coolant level sensor. Refer to Coolant Level Module Replacement in the Engine Cooling sub-section. 3. With the key on, the engine off and the coolant level sensor disconnected from the vehicle wiring harness, observe the low coolant light: • Light is on — Chassis wiring or instrument cluster concern. Follow the appropriate diagnostic information in SI. • Light is out — Proceed to Step 4.

PROBLEM The IMA system indicator comes on and IMA DTC 77 (P1447) (battery module deterioration) or DTC 78 (P1449) (battery module deterioration) is set. CORRECTIVE ACTION Replace the battery module. If needed, replace the motor control module (MCM), the battery condition monitor (BCM), or both. INSPECTION PROCEDURE 1. Turn the ignition switch to LOCK (0). 2. Remove the cargo floor mat (see page 20-44 of the 2000–04 Insight Service Manual). (In ISIS, use the keyword FLOOR MAT, and select Interior Trim Removal/Installation – Cargo Area from the list.) 3. Remove the battery module switch cover (two bolts), then remove the locking cover from the switch. 4. Flip the battery module switch to OFF. Reinstall the locking cover. 5. Wait at least 5 minutes to let the capacitors in the system discharge. 6. Remove the right trunk shelf support (five clips and two bolts). 7. Remove the six mid-frame cover bolts. Remove the intelligent power unit (IPU) lid (17 bolts). 8. Measure the voltage at the junction board terminals. There should be 30 V or less. If you read more than 30 V, there is a problem in the circuit; do the DTC troubleshooting first.
