NOTE The SRS includes the following components: SRS air bag control unit, SRS warning light, front impact sensors, air bag module, clock spring, and interconnecting wiring. Other SRS-related components (that may have to be removed/installed in connection with SRS service or maintenance) are indicated in the table of contents by an asterisk (*). 54A-2 COMBINATION METER . 54A-28 REMOVAL AND INSTALLATION . 54A-73 SERVICE SPECIFICATIONS. 54A-28 INSPECTION . 54A-74 SPECIAL TOOLS. 54A-29 FOG LAMP . 54A-75 TROUBLESHOOTING. 54A-31 DIAGNOSIS FUNCTION . 54A-31 SERVICE SPECIFICATION . 54A-75 DIAGNOSIS CODE CHART . 54A-31 SPECIAL TOOL . 54A-75 DIAGNOSTIC TROUBLE CODE ON-VEHICLE SERVICE . 54A-75 PROCEDURES . 54A-32 FOG LAMP AIMING . 54A-75 BULB REPLACEMENT . 54A-77 TROUBLE SYMPTOM CHART . 54A-42 FOG LAMP . 54A-78 SYMPTOM PROCEDURES. 54A-43 REMOVAL AND INSTALLATION. 54A-78 INSPECTION . 54A-79 DATA LIST REFERENCE TABLE . 54A-59 SIDE TURN-SIGNAL LAMP. 54A-80 ACTUATOR TEST TABLE . 54A-62 SPECIAL TOOL . 54A-80 CHECK AT ECU TERMINALS . 54A-64 REMOVAL AND INSTALLATION . 54A-80 ON-VEHICLE SERVICE. 54A-65 CHECK THE SPEEDOMETER.. 54A-65 ROOM LAMP . 54A-80 TACHOMETER CHECK . 54A-65 FUEL TANK GAUGE UNIT CHECK . 54A-65 ON-VEHICLE SERVICE . 54A-80 REMOVAL AND INSTALLATION . 54A-67 REAR COMBINATION LAMP . 54A-81 DISASSEMBLY AND SPECIAL TOOL . 54A-81 REASSEMBLY. 54A-68 REMOVAL AND HEADLAMP . 54A-69 INSTALLATION . 54A-81 SERVICE SPECIFICATIONS. 54A-69 HIGH-MOUNTED STOP LAMP . 54A-83 ON-VEHICLE SERVICE. 54A-69 HEADLAMP AIMING . 54A-69 HEADLAMP INTENSITY SPECIAL TOOL . 54A-83 MEASUREMENT . 54A-71 BULB REPLACEMENT . 54A-71 REMOVAL AND INSTALLATION . 54A-83 Continued on next page 54A-3 LICENCE PLATE LAMP . 54A-85 TROUBLESHOOTING . 54A-91 TROUBLESHOOTING . 54A-91 TROUBLE SYMPTOM CHART . 54A-92 REMOVAL AND INSTALLATION . 54A-85 SYMPTOM PROCEDURES . 54A-93 HAZARD WARNING LAMP ON-VEHICLE SERVICE . 54A-116 SWITCH . 54A-86 PROCEDURE FOR INPUT OF SECURITY CODE FOR ANTI-THEFT SYSTEM. 54A-116 SPECIAL TOOL. 54A-86 SPEAKER TEST . 54A-117 REMOVAL AND RADIO AND CD PLAYER . 54A-119 INSTALLATION . 54A-86 REMOVAL AND INSTALLATION. 54A-119 INSPECTION . 54A-87 SPEAKER. 54A-120 HORN. 54A-87 REMOVAL AND INSTALLATION . 54A-120 INSPECTION . 54A-87 ROOF ANTENNA . 54A-121 CIGARETTE LIGHTER . 54A-88 REMOVAL AND INSPECTION . 54A-88 INSTALLATION . 54A-121 COLUMN SWITCH. 54A-89 DEFOGGER . 54A-122 SPECIAL TOOL. 54A-89 TROUBLESHOOTING . 54A-122 REMOVAL AND ON-VEHICLE SERVICE . 54A-122 INSTALLATION . 54A-89 PRINTED HEATER LINES CHECK . 54A-122 INSPECTION . 54A-90 DEFOGGER SWITCH . 54A-123 RADIO AND CD PLAYER . 54A-91 REMOVAL AND INSTALLATION . 54A-123 SPECIAL TOOLS. 54A-91 54A-4 CHASSIS ELECTRICAL BATTERY BATTERY SERVICE SPECIFICATIONS M1541000300339 Item Specification Specific gravity of the battery fluid 1.220 − 1.290 (20°C) ON-VEHICLE SERVICE 3. The specific gravity of the battery electrolyte changes according to the temperature, so the FLUID LEVEL AND SPECIFIC GRAVITY specific gravity when the electrolyte is at a CHECK temperature of 20°C can be calculated using the M1541000900159 following formula. Use the converted value to CAUTION judge whether the electrolyte is okay or not.
