Tempo & Topaz
- Ensure all bulbs and fuses are good before proceeding. Remove headlight switch. See HEADLIGHT SWITCH R & I . Test headlight switch positions for continuity. See Fig 1.
- Reconnect headlight switch. Using test light, backprobe connector between terminal B1 and body ground. If test light does not glow, repair open in Black/Orange wire from fusible link "A". See appropriate WIRING DIAGRAMS in this article.
- Using test light, backprobe connector between terminal B2 and body ground. If test light does not glow, repair open in Tan/White wire from fuse block.
- Using jumper wire, connect terminals B1 and "H". If headlights do not operate, check for the following and repair as required:
- Open in Red/Yellow wiring to dimmer switch
- Faulty dimmer switch
- Open in high beam Light Green/Black wiring to both headlights
- Open in low beam Red/Black wiring to both headlights
- Open in ground circuit to headlights
- Using jumper wire, connect terminals B2 and "R". If rear lights and parking lights do not come on, repair open in Brown wiring. If no problem exists in those circuits, repair ground circuit to rear lights. See WIRING DIAGRAMS .NOTE: Circuit "R" also energizes shift indicator dimmer relay located to right of steering column, near warning chime module.
- Using test light, backprobe connector between IGN (ignition) terminal and body ground. Set ignition switch to ACC or RUN position. If test light does not glow, repair open in Yellow/Black wire from fuse No.11.
- Using jumper wire, connect terminals B2 and DN. This circuit is only for LCD lights and electronic radio, no other panel lights should be on. If radio and LCD lights are not on, repair open in Orange/Black wire. Also ensure grounds to LCD lights and electronic radio are good. See appropriate WIRING DIAGRAMS in this article.
- Using jumper wire, connect terminals B2 and "I". If instrument panel lights do not come on, repair open in Light Blue/Red wire to fuse No. 13, and to instrument panel lighting and radio. Ensure individual light assemblies are securely grounded.
- Using test light, backprobe terminal D1 and body ground. This circuit is for dome light and all courtesy lights. If test light does not glow, repair Light Green/Yellow wire to fuse No. 8 and to courtesy lights.
- Using jumper wire, connect terminals D1 and D2. If dome light and both lower instrument panel courtesy lights do not come on, repair open in Black/Light Blue wire. Ensure individual light assemblies are securely grounded.
